Combined technologies create a virtualized security gateway with real-time processing even for small packets associated with IP voice applications.
The future of wireless is ultra-broadband packet throughput, with 4G/LTE speeds hitting 25 Mbps to 50 Mbps¹ and 5G technologies targeting even faster speeds. But the IP mobile networks that are serving up this throughput have new security risks for MNOs that can negatively impact their infrastructure, operations, customer services, and data.
Utilizing security gateways (SeGW) in every base station and small cell is the proven way to secure the network against hackers. But legacy gateways don’t offer the performance or flexibility to scale for cost-effective deployment at a macrocell or at a small cell. Casa Systems worked with Intel and Intel® Network Builders ecosystem members Advantech and Wind River to build a complete virtual SeGW system with the performance and flexibility for these edge locations—even for demanding IP voice applications that transmit floods of small packets that typically have overwhelmed legacy gateways.
This document discusses using distributed firewalls to secure local area networks (LANs). It outlines security issues in LANs like eavesdropping and denial of service attacks. Distributed firewall architectures like Network Edge Security, Automatic Distributed Firewall, and Stateful Clustered Security Gateway are described and compared. The Stateful Clustered Security Gateway distributed firewall is highlighted, which uses multiple firewall nodes working in parallel to filter traffic while providing benefits like fine-grained security, low network load, and fast policy updates.
In Wireless Sensor Networks (WSN), the wireless connections are prone to different type
of attacks. Therefore, security of the data that transfer over the wireless network is a measure
concern in WSN. Due to the limitation of nodes’ energy, efficient energy utilization is also an
important factor. Hence to provide security along with efficient energy utilization of sensor
nodes, Secure and Energy Efficient Hierarchical and Dynamic Elliptic Curve Cryptosystem
(HiDE) scheme is proposed. It includes a hierarchical cluster-based architecture consisting of a
several Area Clusters and a Backbone Network. To provide security Elliptic Curve Cryptography
(ECC) is used. For energy efficient data transmission, Low Energy Adaptive Clustering
Hierarchy (LEACH) is used to select the Cluster Head dynamically. Each Cluster Head collects
the data from their own cluster and transmit to the Destination through the Gateway (GW) in the
Backbone Network. However, limited by the coverage of Gateway, Source Gateway may not be
directly linked with the Destination Gateway in a single hop, so needs to hop through other
Gateways to reach the Destination. Data encryption using Elliptic Curve Cryptography provides
high security with small key size than the existing RSA. Key management includes key
computation, key exchanges, data encryption and decryption. Cluster-based cryptographic
mechanism provides efficient energy utilization of sensor nodes along with security and lower
message overhead. Thus, Hierarchical and Dynamic Elliptic Curve Cryptosystem can protect the
confidentiality of sensitive data with low computation complexity, and also keep the
performance of the network in Wireless Sensor Network.
This document introduces TinySec, a link layer security architecture designed for wireless sensor networks. TinySec aims to provide security such as message authentication and encryption with minimal overhead of bandwidth, latency, and energy consumption. The document discusses the design goals and challenges of sensor network security given constraints of memory, processing power, bandwidth and energy of sensor nodes. It argues that link layer security is better suited than end-to-end security for sensor networks where data aggregation is common. TinySec implements message authentication codes and encryption entirely in software to add security with less than 10% overhead.
A-SURVEY SECURITY PROTOCOL FOR WIRELESS SENSOR NETWORKEditor IJMTER
Nowadays, Wireless Sensor Networks are emerging because of the technological
developments in Wireless Communication. Wireless Sensor Networks are deployed mostly in open
and unguarded environment. The key features of Wireless Sensor Networks are low power, lowmemory, low-energy scaled nodes. Security is a fundamental requirement for Wireless Sensor
Network. Security is the main concern for everything whether it is for wired based network or
wireless based network. Security in Wireless Sensor Network plays an important role in node
communication. For Wireless Sensor Network so many security protocol available but some have

Wireless Sensor Network.
IRJET- - Implementation of a Secured Approach using Dynamic Key Managemen...IRJET Journal
This document proposes a secure authentication approach for wireless sensor networks using dynamic key management and zero knowledge protocols. It begins with background on wireless sensor networks and security issues. It then describes related work on key predistribution and dynamic key management schemes. A proposed algorithm is described that uses a rekeying mechanism, zero knowledge authentication without directly transmitting secret keys, and dynamic keys that change for each authentication. Simulation results on networks of up to 25 nodes show the approach is efficient and can authenticate nodes while preventing attacks like cloning.
AN ANTI-CLONE ATTACK KEY MANAGEMENT SCHEME FOR WIRELESS SENSOR NETWORKScsandit
Wireless Sensor Networks (WSNs) are subject to various kinds of attacks such as replaying of
messages, battery exhausting, and nodes compromising. While most of these attacks can be
dealt with through cryptographic security protocols provided by key management schemes,
there are always a few that manage to really cause problems. One such attack that is most
common and significant in WSNs is cloning attack. In clone attack, the intruder tries to capture
and compromise some nodes and inject them into several locations throughout the network in
order to conduct other types of attacks. Moreover, if this attack is not detected early, then these
replicated injected nodes will consume a large amount of the network resources. In this paper,
we analyze several key management schemes that can be used for checking integrity and
preventing cloning attacks. After analyzing the problems associated with these schemes, we
propose a model that allows us to distinguish between legitimate nodes and cloned nodes in
such sensor networks.
The document discusses security vulnerabilities and requirements in sensor networks. It outlines various security attacks that can occur at different network layers. Key management is identified as an important mechanism for security. Public key cryptography algorithms like Elliptic Curve Cryptography (ECC) are optimized solutions for sensor networks due to their lower computational overhead compared to algorithms like RSA. The document also reviews different key management protocols and concludes by recommending ECC for its ability to provide robust security while reducing storage and communication costs in resource-constrained sensor networks.
This document describes TinyECC, a configurable library for elliptic curve cryptography (ECC) operations in wireless sensor networks.

Certain Investigations on Security Issues in Smart Grid over Wireless Communi...IJTET Journal
Smart Grid (SG) communication has recently received significant attentions to facilitate intelligent and distributed electric power transmission systems. The advent of the smart grid promises to user in an era that will bring intelligence, efficiency, and optimality to the power grid. Most of these challenges will occur as an Internet-like communications network is super imposed on top of the current power grid using wireless mesh network technologies with the 802.15.4, 802.11 and WiMAX Standards. Each of these will expose the power grid to security threats. Wireless communication offers the benefits of low cost, rapid deployment, shared communication medium, and mobility. It causes many security and privacy challenges. The concept of dynamic secret is applied to design an encryption scheme for smart grid in wireless communication. Between two parties of communication, the previous packets are coded as retransmission sequence, where retransmitted packet is marked as ―1‖ and the other is marked as ―0‖.During the communication, the retransmission sequence is generated at both sides to update the dynamic encryption key. Any missing or misjudging sequence would prevent the adversary from achieving key. A Smart Grid platform is built, employing the ZigBee protocol for wireless communication. The Simulation results show that the retransmission and packet loss in ZigBee communication are inevitable and unpredictable and it is impossible of the adversary to track the updating of dynamic encryption key. Even though the DES scheme can protect the encryption key from attackers, the hackers can obtain the keys some time, due to the block size 64 bits used by DES that makes the adversary (hacker) to hack the data. It introduces vulnerabilities and liner crypt analysis; this can be achieved by using AES scheme. The AES uses 128 bits block size for a single encryption key a data of 256 billion gigabytes can be transmitted thus its provide much more safety to user from hacker and it reduces the end to end delay and increases packet transmission rate.
The document summarizes vulnerabilities in the WEP and WPA2 wireless security protocols. It provides an overview of how each protocol works, algorithms used, and known weaknesses. Procedures are described for cracking WEP and WPA2 networks using the Aircrack-ng software suite by capturing packets to obtain keys. Both WEP and WPA2 were shown to be vulnerable to attack, with WEP cracking taking 15-20 minutes and WPA2 cracking using a dictionary attack on captured handshake data.
Random key material distribution in wireless sensor networksVarsha Anandani
The document discusses random key material distribution for securing wireless sensor networks. It first provides background on wireless sensor networks and their design challenges. It then discusses security issues like authentication and key agreement. It describes threats like node duplication and wormhole attacks. The document proposes distributing a random subset of keys from a large pool to each sensor node so they can find common keys to securely communicate and form a connected network, without a central trusted authority. However, compromising enough nodes could allow reconstructing the full key pool.
CERTIFICATELESS SCHEME BASED NTRU CRYPTOSYSTEM FOR AD-HOC UWB-IR NETWORKijwmn
From the radar and military research world’s, the Ultra-WideBand Impulse Radio (UWB-IR) was
adopted in the telecommunications world in the 1990’. Currently, the UWB-IR technology is an
interesting candidate for close range Wireless Sensors Networks (WSNs). It is particularly attractive
for industrial sensor networks due to its resilience to multipath interference, simple transceiver
circuitry, accurate ranging ability, and low transmission power. In order to secure data and communications
in the Ad-Hoc UWB-IR networks, UWB-IR requires suitable encryption protocols. In
this paper, we review and summarize the IEEE 802.15.4 security sub-layer protocol of UWB-IR
based Symmetric Key Cryptography scheme. Then, we highlight the different vulnerabilities and
weaknesses present in this type of scheme. Finally, we prove, after a deep examination of multiple
Public Key Cryptography (PKC) schemes, that the certificateless one is the most suitable for Ad-Hoc
UWB-IR networks characterized by nodes mobility. Indeed, we have also evaluated and analyzed the
different public key cryptosystems (PKCS) and concluded that NTRU is the most optimum public
key cryptosystem to be used with the certificateless scheme in order to secure data and communications
in Ad-Hoc UWB-IR Networks. This is due to the fact that it is the fastest PKCS to provide
different security levels at a high speed with very constrained resources.

A Survey Paper On Data Confidentiatity And Security in Cloud Computing Using ...IJSRD
Now days rapidly increased use of cloud computing in the many organization and IT industries and provides latest software solution with minimum cost. So the cloud computing give us number of benefits with minimum cost and of data accessibility through Internet. The ensuring security risks of the cloud computing is the main factor in the cloud computing environment, The evolving essence is Cloud computing, that is beneficial in cost effective parts, such as capability inflexible computing, decreasing the time period to market and insufficient computing power. By using the complete ability of cloud computing, data are transmitted, processed and stored on the outside cloud service providers. The fact is that, the owner of the data is feeling extremely unconfident to locate their data outer to their own control. Security and Confidentiality of data stored in the cloud are key setbacks in the area of Cloud Computing. Security and Confidentiality are the key issues for cloud storage. This paper proposes a KIST encryption algorithm to concentrate on the security and Confidentiality issues in cloud storage and also compressed cipher text data in order to protect the data stored in the cloud.
1. Wireless sensor networks consist of spatially distributed sensor nodes that can sense their environment, process data, and communicate wirelessly. They are useful for monitoring remote structures and environmental changes.
2. In a cluster-based wireless sensor network, sensor nodes are organized into clusters with a cluster head that collects data from nodes in its cluster and sends it to the base station. Identity-based cryptography is used where a node's public key is derived from its identity information like its ID number.
3. An identity-based online/offline digital signature scheme separates the signature generation process into an offline stage and online stage. The offline stage is pre-computed and the online stage combines it with the message for the final signature
This document summarizes a seminar on secure and efficient data transmission for cluster-based wireless sensor networks. It introduces wireless sensor networks and describes their centralized and hierarchical network architectures. It reviews previous work on the LEACH clustering protocol and its pros and cons. It then proposes two new secure transmission protocols called SET-IBS and SET-IBOOS that use identity-based signatures and offline/online signatures respectively to authenticate data transmitted between sensor nodes and cluster heads. The document analyzes the performance and security of the proposed protocols and discusses their applications and potential for future work.
The document describes a security protocol called SPINS (Security Protocols for Sensor Networks) that is optimized for resource-constrained wireless sensor networks. SPINS consists of two security building blocks: SNEP and TESLA. SNEP provides data confidentiality, authentication, integrity and freshness with low overhead. TESLA provides authenticated broadcast, which is challenging for sensor networks. The protocols were implemented on prototype sensor nodes and shown to perform well within the limited capabilities of the hardware.
As sensor networks edge closer towards wide-spread placement, security issues become a central concern. So far, much research has concentrated on making sensor networks feasible and useful, and has not focused on security.
We present a set of security building blocks optimized for resource constrained environments and wireless communication. SPINS has two secure building blocks: SNEP and TESLA. SNEP provides the following important baseline security primitives: Data confidentiality, two-party data authentication, and data freshness. A particularly hard problem is to provide effective broadcast authentication, which is an important mechanism for sensor networks. TESLA is a new protocol which provides authenticated broadcast for severely resource-constrained surroundings. We realized the above protocols, and show that they are practical straighly on minimal hardware: the performance of the protocol suite easily matches the data rate of our network. Additionally, we prove that the suite can be used for building higher level protocols
Hierarchical Key Agreement Protocol for Wireless Sensor Networksidescitation
This document proposes a hierarchical key agreement protocol for wireless sensor networks that uses both symmetric and asymmetric cryptographic techniques. Specifically, it uses probabilistic key pre-distribution for sensor nodes within clusters to establish secure communication with low computational overhead. It uses identity-based asymmetric key distribution between cluster heads and the base station to achieve secure communication with low communication overhead. The goal is to balance security, resilience, and resource overhead of the key management protocol for the constrained sensor nodes. It provides mathematical background on bilinear pairings and elliptic curves needed to implement the identity-based cryptographic techniques.

With the advent of Wireless Sensor Networks (WSN) and its immense popularity in a wide range of applications, security has been a major concern for these resource-constraint systems. Alongside security, WSNs are currently being integrated with existing technologies such as the Internet, satellite, Wi-Max, WiFi, etc. in order to transmit data over long distances and hand-over network load to more powerful devices. With the focus currently being on the integration of WSNs with existing technologies, security becomes a major concern. The main security requirement for WSN-integrated networks is providing end-to-end security along with the implementation of in-processing techniques of data aggregation. This can be achieved with the implementation of Homomorphic encryption schemes which prove to be computationally inexpensive since they have considerable overheads. This paper addresses the ID-issue of the commonly used Castelluccia Mykletun Tsudik (CMT) [12] homomorphic scheme by proposing an ID slotting mechanism which carries information pertaining to the security keys responsible for the encryption of individual sensor data. The proposed scheme proves to be 93.5% lighter in terms of induced overheads and 11.86% more energy efficient along with providing efficient WSN scalability compared to the existing scheme. The paper provides analytical results comparing the proposed scheme with the existing scheme thus justifying that the modification to the existing scheme can prove highly efficient for resourceconstrained WSNs.

Providing user security guarantees in public infrastructure cloudsKamal Spring
The infrastructure cloud (IaaS) service model offers improved resource flexibility and availability, where tenants – insulated from the minutiae of hardware maintenance – rent computing resources to deploy and operate complex systems. Large-scale services running on IaaS platforms demonstrate the viability of this model; nevertheless, many organizations operating on sensitive data avoid migrating operations to IaaS platforms due to security concerns. In this paper, we describe a framework for data and operation security in IaaS, consisting of protocols for a trusted launch of virtual machines and domain-based storage protection. We continue with an extensive theoretical analysis with proofs about protocol resistance against attacks in the defined threat model. The protocols allow trust to be established by remotely attesting host platform configuration prior to launching guest virtual machines and ensure confidentiality of data in remote storage, with encryption keys maintained outside of the IaaS domain. Presented experimental results demonstrate the validity and efficiency of the proposed protocols. The framework prototype was implemented on a test bed operating a public electronic health record system, showing that the proposed protocols can be integrated into existing cloud environments.
This document proposes using certificate authorities and elliptic curve cryptography to improve security in Zigbee wireless sensor networks.

Finally, it recommends an innovative hybrid solution combining certificate authorities and ECC to further reduce vulnerabilities when nodes enter or exit large-scale IoT networks.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Secure and Efficient Data Transmission for Cluster-based Wireless
Sensor Networks
ABSTRACT
Secure data transmission is a critical issue for wireless sensor networks (WSNs).Clustering is an
effective and practical way to enhance the system performance of WSNs. In this paper, we study a secure data
transmission for cluster-based WSNs (CWSNs), where the clusters are formed dynamically and periodically.
We propose two Secure and Efficient data Transmission (SET) protocols for CWSNs, called SET-IBS and SET-IBOOS,
by using the Identity-Based digital Signature (IBS) scheme and the Identity-Based Online/Offline
digital Signature (IBOOS) scheme, respectively. In SET-IBS, security relies on the hardness of the Diffie-
Hellman problem in the pairing domain. SET-IBOOS further reduces the computational overhead for protocol
security, which is crucial for WSNs, while its security relies on the hardness of the discrete logarithm problem.
We show the feasibility of the SET-IBS and SET-IBOOS protocols with respect to the security requirements
and security analysis against various attacks. The calculations and simulations are provided to ] illustrate the
efficiency of the proposed protocols. The results show that, the proposed protocols have better performance
than the existing secure protocols for CWSNs, in terms of security overhead and energy consumption.
Existing System
In this Existing System of wireless sensor network comprised of spatially distributed devices using
wireless sensor nodes to monitor physical or environmental conditions, such as sound, temperature, and motion.
2. The individual nodes are capable of sensing their environments, processing the information data locally, and
sending data to one or more collection points in a WSN.
Efficient data transmission is one of the most important issues for WSNs. Meanwhile, many WSNs are
deployed in harsh, neglected and often adversarial physical environments for certain applications, such as
military domains and sensing tasks with trustless surroundings
Proposed System
In this Proposed System, Secure and efficient data transmission is thus especially necessary and is
demanded in many such practical WSNs. So, we propose two Secure and Efficient data Transmission (SET)
protocols for CWSNs, called SET-IBS and SET-IBOOS, by using the Identity-Based digital Signature (IBS)
scheme and the Identity-Based Online/O ffline digital Signature (IBOOS) scheme, respectively.
It has been proposed in order to reduce the computation and storage costs to authenticate the encrypted
sensed data, by applying digital signatures to message packets, which are efficient in communication and
applying the key management for security.
In the proposed protocols pairing parameters are distributed and preloaded in all sensor nodes by the BS
initially.

f. Attack resilience
Modules Description
3. SET Protocol
In this module, Secure and Efficient data Transmission (SET) protocol for CWSNs. The SET-IBOOS
protocol is designed with the same purpose and scenarios for CWSNs with higher efficiency. The proposed
SET-IBOOS operates similarly to the previous SETIBS, which has a protocol initialization prior to the network
deployment and operates in rounds during communication. We first introduce the protocol initialization, then
describe the key management of the protocol by using the IBOOS scheme, and the protocol operations
afterwards.
Key management for security
In this module, security is based on the DLP in the multiplicative group. The corresponding private
pairing parameters are preloaded in the sensor nodes during the protocol initialization. The IBOOS scheme in
the proposed SET-IBOOS consists of following four operations, extraction, offline signing, online signing and
verifications.
Key management
In this Module, the key cryptographies used in the protocol to achieve secure data transmission, which
consist of symmetric and asymmetric key based security. • Neighborhood authentication
In this module, used for secure access and data transmission to nearby sensor nodes, by authenticating
with each other. Here, “limited” means the probability of neighborhood authentication, where only the nodes
with the shared pairwise key can authenticate each other.
Storage cost
In this module, represents the requirement of the security keys stored in sensor node’s memory.
Network scalability
In this module, indicates whether a security protocol is able to scale without compromising the security
requirements. Here, “comparative low” means that, compared with SET-IBS and SET-IBOOS, in the secure
data transmission with a symmetric key management, the larger network scale increases, the more orphan nodes
appear in the network.
Communication overhead
In this module, the security overhead in the data packets during communication. • Computational
overhead
In this module, the energy cost and computation efficiency on the generation and verifications of the
certificates or signatures for security.
4. Attack resilience
In this module, the types of attacks that security protocol can protect against.
