The document discusses Internet Key Exchange (IKE), which establishes secure communication channels within a network by facilitating the exchange of cryptographic keys and negotiation of security parameters. IKE is an integral part of security policies and ensures confidentiality, integrity, and authenticity of data transmissions. It has two phases - Phase 1 establishes an initial secure channel and authenticates peers, while Phase 2 further refines security parameters and establishes encryption keys. Phase 1 can operate in two modes: Main Mode provides stronger identity protection through encrypted negotiation, while Aggressive Mode has a faster setup but less secure identity handling.
Design methodology for ip secured tunel based embedded platform for aaa serverijmnct
Authentication, Authorization, and Accounting (AAA) Server application provides users AAA services for
network devices and mobile software applications. In authentication process if a user is requesting services
with IP security highly customized hardware platform server with IP security protocol is required to handle
validity of user for the network services. Development and testing of IPSec platform is a great challenge
and this platform provides various IP security services for traffic at IP layer in both IPv4 and IPv6.It also
provides encryption and decryptions of the payload of IP packets between communicating servers.
Authentication process is accomplished via the presentation of an identity and credentials. This paper
describes the methodology to develop and evaluate the embedded IP security platform for AAA server for
IP sec network users. IPSec network users need to authenticate themselves to the AAA server application
when they want to communicate with it. AAA Server application uses RADIUS/DIAMETER protocol and
Extensible Authentication Protocol (EAP) to provide user AAA services. Finally results shows embedded IP
security platform for AAA server is developed and tested successfully for IPSec network users.
Internet Key Exchange (IKE) is a standard protocol that sets up a secure and authenticated communication channel between two parties using a virtual private network (VPN). There are two versions, IKEv1 defined in RFC 2409 and IKEv2 defined in RFC 7296. IKE uses X.509 certificates for authentication and Diffie-Hellman key exchange to establish a shared secret session. It works as part of the IPsec protocol suite to provide security for IP packets and secure VPNs. IKE sets up secure communications channels in two phases - phase 1 establishes an authenticated connection using preshared keys or certificates for secure phase 2 communications using Diffie-Hellman key exchange. Potential challenges include vulnerabilities in IKEv1 and requiring additional configurations
IPSec VPN provides secure communication over insecure networks using encryption, integrity checks, authentication, and anti-replay features. It uses IKE to establish security associations between peers, exchanging proposals and keys. IKE then uses ESP or AH to encrypt packets and verify integrity using hashes or signatures to prevent tampering. Digital certificates or pre-shared keys authenticate the origins of data through public key infrastructure or shared secrets.

A NEW COMMUNICATION PLATFORM FOR DATA TRANSMISSION IN VIRTUAL PRIVATE NETWORKijmnct
Nowadays security is an evident matter in designing networks and much research has been done in this
field. The main purpose of the research is to provide an appropriate instruction for data transmission in a
reliable platform. One of the instructions of transferring information is to use public networks like internet.
The main purpose of the present paper is to introduce that enables the users to enter to a new security level.
In this paper, VPN as one of the different instructions for establishing the security proposed to be
examined. In this type, tunneling method of internet protocol security (IPsec) is used. Furthermore, the
advanced method of scanning fingerprint is applied to establish authentication and Diffie-Hellman
algorithm for coding and decoding data, of course with conversion in this algorithm.
Internet Protocol Security (IP Security) is a security protocol that serves to secure information in the event of an exchange on the internet. It happens if there is a connection between private IP and public IP. This protocol will exchange packets on the IP layer safely. It provides two types of encryption options, transport, and tunnel. Transport mode will encrypt the data section without changing the packet header. The algorithm used to encrypt data is a symmetric cryptography algorithm. This protocol authenticates and encrypts every packet from a data transmission session. Also, it can generate keys between the sender and the recipient at the first time it is activated and can negotiate the cryptographic keys that will be used during the session. IP Security is an end-to-end cryptosystem that works at the internet layer of the Internet Protocol Suite. The protocol serves to protect the data flow in host-to-host, network-to-network, and network-to-host as well.

IMPLEMENT A NOVEL SYMMETRIC BLOCK CIPHER ALGORITHMijcisjournal
Cryptography technology is a security technique used to change plain text to another shape of data or to symbols, which is known as the cipher text. Cryptography aims to keep the data secure during its journey through public networks. Currently, there are many proposed algorithms that provide this service especially for sensitive data or very important conversations either through mobile or video conferences. In this paper, an inventive security symmetric algorithm is implemented and evaluated, and its performance is compared to the AES. The algorithm has four different rounds for each quarter of the key container table, and each of them serves to shift the table. The algorithm uses the XOR operation, which, being lightweight and cheap, is very appropriate for use with Real Time Applications. The result shows that the suggested algorithm spends less time than AES although it has 16 rounds and the numbers used to mix up the table are big.

SURVEY AND TAXONOMY OF KEY MANAGEMENT PROTOCOLS FOR WIRED AND WIRELESS NETWORKSIJNSA Journal
The purpose of this paper is to survey the key management protocols for wired and wireless networks and study their security aspects in terms of key generation, agreement and distribution. The central research challenge is exhaustive survey of secure and efficient key management protocols. In this survey, it is shown that all these protocols could be placed under one of two key management protocol categories: (i)
peer to peer communication and (ii) group communication. This can also be analyzed that peer to peer key management can be classified as: (i) symmetric key, (ii) asymmetric key and (iii) hybrid key management protocols and group communication can further be classified as: (i) Diffie-Hellman based (ii)Hybrid key management. We can say that our theoretical and execution analysis of protocols emphasise various observations that can motivate researchers in key management issues of networks.
IPSec is a protocol suite that provides security for IP communications by authenticating and encrypting each IP packet. It was created because the original IP protocol lacked security features to prevent spoofing, replay attacks, and ensure confidentiality. IPSec includes protocols like AH, ESP and IKE to provide authentication, integrity, confidentiality, and secure key establishment between network devices. It operates in either transport or tunnel mode and can be configured using IPSec policies to determine when and how to apply security to network traffic.
Wireless Network Security Architecture with Blowfish Encryption ModelIOSR Journals
Abstract: In this research paper ,we developed a model for a large network, wireless nodes are interconnected and each can be considered as a node processor that offer services to other node processors connected to a specific network. A very high proportion of the nodes that offer services need to carry out an authentication process so as to make an access request to the node offering the service. In this context, an integrated reconfigurable network security architecture moved to the application layer has become the need of the day for secure wireless data sharing. The security schemes of the seven layer OSI architecture need to be placed intrinsically in the wireless node itself and should be capable of supporting the MAC layer, IP address based layer and the routing protocols of the network layer. This work focuses on the use of emulator and embedded hardware architectures for wireless network security. In this work, the individual nodes can have a unique security signature pattern maintained by respective wireless nodes using an encryption algorithm and this is made dynamic.

Providing security in group communication is more essential in this new network environment. Authentication and Confidentiality are the major concerns in secure group
communication. Our proposed approach uses an authenticated group key transfer protocol that relies on trusted key generation center (KGC). KGC computes group pair for each
individual and transport the pair of values to all group members in a secured manner. Password based authentication mechanism is used to avoid the illegal member access in a
group Also, the proposed approach facilitates efficient key computation technique such that only authorized group members will be able to computer and retrieve the secret key and unauthorized members cannot retrieve the key. The proposed algorithm is more efficient and relies on NP class. In addition, the distribution of key is also safe and secure. Moreover, the pair generated for the computation of key is also very strong since the cryptographic techniques are used which provides efficient computation.

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
This talk will cover ScyllaDB Architecture from the cluster-level view and zoom in on data distribution and internal node architecture. In the process, we will learn the secret sauce used to get ScyllaDB's high availability and superior performance. We will also touch on the upcoming changes to ScyllaDB architecture, moving to strongly consistent metadata and tablets.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Introduction:
Internet Key Exchange (IKE) is a protocol used in the IPsec (Internet Protocol Security) suite
to establish a secure and authenticated communication channel between two devices.
Overview of IPsec:
IPsec, or Internet Protocol Security, is a comprehensive suite of protocols and standards
designed to secure Internet Protocol (IP) communications.
The IP protocol itself doesn't have any security features at all.
IPSec is a framework that helps us to protect IP traffic on the network layer.
FIG 1 : IKE BLOCK
FIG2 : IPSEC BLOCK
5. 4
Key Aspects of IPsec are as follows
1. Security Services:
Confidentiality: IPsec can encrypt the data payload of IP packets, ensuring
that the information is not readable by unauthorized entities.
Integrity: IPsec uses cryptographic mechanisms to ensure the integrity of the
transmitted data, detecting and preventing tampering.
Authentication: IPsec provides methods for authenticating the identities of
communicating parties, ensuring that the data is exchanged between trusted
entities.
Replay Protection: IPsec guards against replay attacks by incorporating
mechanisms to detect and discard duplicated or delayed packets.
2. Security Protocols:
Authentication Header (AH): AH provides authentication and integrity
protection for the entire IP packet, including both the header and the payload.
Encapsulating Security Payload (ESP): ESP primarily provides
confidentiality for the payload of the IP packet, but it can also include optional
authentication and integrity protection.
3. Key Management:
IPsec relies on cryptographic keys for securing communications. Key
management protocols, such as the Internet Key Exchange (IKE), are used to
negotiate and exchange these keys securely.
4. Modes of Operation:
Transport Mode: In transport mode, only the payload (data) of the IP packet
is encrypted and/or authenticated. The original IP header remains intact.
Tunnel Mode: In tunnel mode, the entire original IP packet (including the
header) is encapsulated within a new IP packet. This is often used in VPNs to
protect entire communication streams between networks.
6. 5
Internet Key Exchange
Before we can protect any IP packets, we need two IPSec entity that build the IPSec
tunnel
To establish an IPSec tunnel, we use a protocol called IKE (Internet Key Exchange).
There are two phases
IKE phase 1: Mutual authentication and session keys
IKE phase 2: Use results of phase 1 to create multiple associations between the same entities
IKE PHASE-1:
Internet Key Exchange (IKE) Phase 1 is the initial stage of the IKE protocol used in the IPsec
(Internet Protocol Security) suite to establish a secure and authenticated communication
channel between two devices
During Phase 1, the devices negotiate and establish a secure preliminary connection,
including the exchange of keying material and the establishment of a secure channel for
further negotiations in Phase 2.
The key components and steps involved in IKE Phase 1:
1. Initiation of IKE Session:
The IKE Phase 1 process begins with the initiation of an IKE session by one
of the communicating devices. This device is typically referred to as the
initiator.
2. Proposal and Selection of Security Parameters:
The initiator proposes a set of security parameters, including encryption
algorithms, integrity algorithms, and a method for authentication (such as pre-
shared keys or digital certificates).
FIG 3 :IKE PHASE-
7. 6
3. Responder's Response:
The responder, which is the other device in the communication, evaluates the
proposals received from the initiator and selects the appropriate security
parameters based on its own policies and capabilities.
4. Diffie-Hellman Key Exchange:
The devices perform a Diffie-Hellman key exchange to establish a shared
secret. This shared secret is used to derive the symmetric keys that will be
used for securing further communications.
5. Authentication:
The devices authenticate each other using the agreed-upon authentication
method. This can involve the exchange of digital certificates, pre-shared keys,
or other methods, depending on the chosen authentication mechanism.
6. Creation of IKE Phase 1 SA (Security Association):
Once the Diffie-Hellman exchange and authentication are successful, the
devices create an IKE Phase 1 SA. This SA contains the negotiated security
parameters, the shared secret, and other relevant information needed for secure
communication.
7. Establishment of Secure Channel:
With the IKE Phase 1 SA established, the devices have a secure channel
through which they can conduct further negotiations, including the
establishment of additional SAs for data encryption and integrity protection in
IKE Phase 2.
IKE Phase 1 lays the groundwork for a secure and authenticated communication session.
Once Phase 1 is completed, the devices proceed to IKE Phase 2 to further refine the security
parameters and establish the specific parameters for data encryption and protection.
Two peers negotiate about the oncryption, authentication, hashing and other protocols that
they want to use and some other parameters that are required.
In this phase, an ISAKMP (Internet Security Association and Key Management
Protocol) session is established.
This is also called the ISAKMP tunnel or IKE phase 1 tunnel.
The collection of parameters that the two devices will use is called a SA (Security
Association).
Steps in Phase 1
The main purpose of IKE phase 1 is to establish a secure tunnel that we can use for IKE
phase 2.
8. 7
We can break down phase 1 in three simple steps:
Step 1: Negotiation : The two peers will negotiate about the following items:
Hashing (MD5, SHA)
Authentication (Pre-shared keys, DSS, etc)
DH (Diffie Hellman) parameters
Lifetim
Encryption (DES, 3DES, IDEA)
Step 2: DH Key Exchange: Both entities use the DH group that they negotiated to exchange
keying material. The end result will be that both peers will have a shared key.
Step 3: Authentication: The two peers will authenticate each other using the authentication
method that they agreed upon on in the negotiation. The end result is a IKE phase 1 tunnel
(ISAKMP tunnel) which is bidirectional.
Modes of Phase 1
The three steps above can be completed using two different modes:
Main mode
Aggressive mode
Main Mode:
IKE Phase 1 Main Mode is one of the two modes used for negotiating the initial connection
and establishing the first set of Security Associations (SAs) in the Internet Key Exchange
(IKE) protocol within the context of IPsec (Internet Protocol Security). Main Mode is
characterized by a more robust and secure negotiation process, making it suitable for
scenarios where a higher level of security is required.
Main Mode is considered more secure than the alternative IKE Phase 1 Aggressive Mode
because it provides additional protection for the identities of the communicating peers. This is
achieved by encrypting and authenticating the identities within the negotiation process,
enhancing the overall security of the initial connection.
9. 8
the key features of IKE Phase 1 Main Mode:
1. Six-Message Exchange:
Main Mode consists of a six-message exchange between the initiator and
responder. These messages are used for negotiating keying material and
establishing the initial Security Association.
2. Identity Protection:
Main Mode provides protection for the identities of the communicating peers
during the negotiation process. This is achieved through the use of encryption
and integrity protection for certain parts of the IKE messages.
3. Key Exchange and Authentication:
Main Mode includes the exchange of Diffie-Hellman public keys for secure
key exchange. It also incorporates authentication methods, such as digital
FIG 4:MAIN MODE
10. 9
signatures or shared secret keys, to ensure the identities of the communicating
parties.
4. Protection Against Eavesdropping:
Main Mode is designed to resist eavesdropping attacks by protecting the
exchanged information, including the identities and keying material, with
encryption and integrity checks.
5. Negotiation of Security Parameters:
During Main Mode, the negotiating parties propose and agree upon security
parameters, such as encryption algorithms, integrity algorithms, and
authentication methods. The negotiation process aims to establish a common
set of parameters that both parties can use for secure communication.
6. Creation of IKE Phase 1 SA:
Upon successful completion of the Main Mode negotiation, an IKE Phase 1
Security Association (SA) is established. This SA contains the agreed-upon
security parameters, the Diffie-Hellman shared secret, and other information
necessary for secure communication.
Aggressive mode:
IKE Phase 1 Aggressive Mode is another method used for negotiating the initial connection
and establishing the first set of Security Associations (SAs) in the Internet Key Exchange
(IKE) protocol within the context of IPsec (Internet Protocol Security).
11. 10
The key features of IKE Phase 1 Aggressive Mode:
1. Three-Message Exchange:
Aggressive Mode uses a three-message exchange between the initiator and
responder. This streamlined process allows for a faster setup compared to the
six-message exchange of Main Mode.
2. Simplified and Faster Negotiation:
Aggressive Mode simplifies the negotiation process by combining the first two
messages of Main Mode into a single message, reducing the number of round-
trip communications required to establish the initial connection. This leads to
quicker setup times.
3. Less Identity Protection:
Unlike Main Mode, Aggressive Mode provides less protection for the identities
of the communicating peers during the negotiation process. The identities are
exchanged in the clear, making them potentially vulnerable to eavesdropping.
4. Key Exchange and Authentication:
Aggressive Mode includes the exchange of Diffie-Hellman public keys for key
exchange. It also incorporates authentication methods, such as digital signatures
or shared secret keys, to ensure the identities of the communicating parties.
5. Efficiency vs. Security Trade-off:
Aggressive Mode is often chosen in situations where the efficiency of the setup
process is prioritized over certain aspects of identity protection. It is suitable for
scenarios where the communicating parties are not as concerned about the
potential exposure of their identities during the negotiation.
6. Creation of IKE Phase 1 SA:
Similar to Main Mode, upon successful completion of the Aggressive Mode
negotiation, an IKE Phase 1 Security Association (SA) is established. This SA
contains the agreed-upon security parameters, the Diffie-Hellman shared secret,
and other information necessary for secure communication.
12. 11
IKE PHASE 2:
IKE Phase 2, also known as the Quick Mode, follows the completion of IKE Phase 1 (either
Main Mode or Aggressive Mode) and is the second stage of the Internet Key Exchange (IKE)
protocol within the IPsec (Internet Protocol Security) suite. In Phase 2, the primary focus is
on negotiating the parameters for data encryption and integrity protection, establishing the
specific Security Associations (SAs) that will be used for securing the actual data traffic
between two device.
1. Negotiation of IPsec SAs:
IKE Phase 2 negotiates the parameters for the IPsec Security Associations that
will be applied to the actual data traffic. These parameters include the
encryption algorithm, integrity algorithm, and the duration for which the keys
should be valid.
2. Selection of IPsec Transform Sets:
Transform sets specify the algorithms and settings for encryption,
authentication, and other security features. During Phase 2, the negotiating
parties agree on a common set of transform sets that will be used to protect the
data.
3. Perfect Forward Secrecy (PFS):
PFS is an optional feature in IKE Phase 2 that ensures even higher security. If
PFS is enabled, new Diffie-Hellman keys are exchanged for each Phase 2
negotiation, providing forward secrecy and enhancing the security of the
communication.
4. Creation of IPsec SAs:
Upon successful negotiation, IKE Phase 2 establishes the IPsec SAs. These
SAs contain the agreed-upon parameters for securing the data, including the
keys derived from the Phase 1 negotiation.
5. Renegotiation and Rekeying:
IPsec SAs have a limited lifetime to enhance security. IKE Phase 2 provides
the mechanism for renegotiating and rekeying SAs to ensure that the security
13. 12
parameters are regularly updated and to prevent potential vulnerabilities
associated with long-term key usage.
6. Data Protection:
Once IKE Phase 2 is complete, the established IPsec SAs are used to protect
the actual data traffic between the devices. This includes encrypting the
payload of IP packets and ensuring the integrity of the transmitted data.
IKE Phase 2 builds upon the foundation established in Phase 1 and focuses on securing the
data communication between the devices. The negotiation of IPsec SAs and the establishment
of transform sets during this phase play a crucial role in defining how the actual data will be
protected as it traverses the network.

3. Interoperability Challenges: Despite being standardized, interoperability issues may
arise, especially when dealing with devices from different vendors.
4. Resource Intensive: The cryptographic operations involved in IKE can be resource-
intensive, impacting the performance of devices, particularly those with limited
processing power.
5. Potential for Brute Force Attacks: Weak pre-shared keys or passwords may be
susceptible to brute force attacks, compromising the security of the system.
6. Quantum Computing Concerns: The emergence of powerful quantum computers
could potentially undermine the security of cryptographic algorithms used in IKE,
posing a long-term security concern.
