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.

Review on AES Algorithm Based Secure Data Transmission for Wireless Sensor Ne...EECJOURNAL
Due to vast development of information technology the need of the protection of data also increases for that purpose encryption is done. The security requirements include four major aspect data confidentiality, data integrity, data authentication and data freshness. WSNs have produced enormous enthusiasm among analysts these years in view of their potential utilization in a wide assortment of uses. Sensor hubs are cheap compact gadgets with restricted handling force and vitality assets. Sensor hubs can be utilized to gather data from the earth, locally process this information and transmit the detected information back to the client. For securing that data from attack many algorithms came in existence for cryptography purpose. Be that as it may, the outstanding amongst other existing symmetric security calculation to give information security utilized these days is Advanced encryption standard (AES).
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.
Virtual security gateways at network edge are key to protecting ultra broadba...Paul Stevens
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.
Protecting location privacy in sensor networks against a global eavesdropperJPINFOTECH JAYAPRAKASH
The document proposes two techniques - periodic collection and source simulation - to prevent leakage of location information in sensor networks from a global eavesdropper. Periodic collection provides high location privacy while source simulation provides tradeoffs between privacy, communication cost, and latency. The techniques are efficient and effective at providing source and sink location privacy compared to existing methods that only defend against local adversaries.
This document summarizes security schemes for wireless sensor networks, including TinySec, IEEE 802.15.4, and others. It discusses the challenges of WSNs like power constraints and limited resources. It also outlines common security threats to WSNs such as denial of service attacks, attacks on information in transit, Sybil attacks, black hole/sinkhole attacks, and hello flood attacks. The document evaluates the feasibility of applying basic security schemes like cryptography and steganography to WSNs given their unique constraints and requirements.

This document discusses network security and cryptography. It begins by defining network security and explaining the key areas of secrecy, authentication, non-repudiation, and integrity control. It then discusses what cryptography is, explaining that it uses mathematics to encrypt and decrypt data to provide security. The document provides an overview of symmetric and asymmetric key encryption techniques as well as hash functions. It also discusses some existing network security systems and their use of symmetric encryption with periodic key distribution and refresh.
Even in difficult places to reach, the new networking technique allows the easy deployment of sensor networks although these wireless sensor networks confront a lot of constraints. The major constraint is related to the quality of information sent by the network. The wireless sensor networks use different methods to achieve data to the base station. Data aggregation is an important one, used by these wireless sensor networks. But this aggregated data can be subject to several types of attacks and provides security is necessary to resist against malicious attacks, secure communication between severely resource constrained sensor nodes while maintaining the flexibility of the topology changes. Recently, several secure data aggregation schemes have been proposed for wireless sensor networks, it provides better security compared with traditional aggregation. In this paper, we try to focus on giving a brief statement of the various approaches used for the purpose of secure data aggregation in wireless sensor networks.

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.

The document examines challenges for unattended wireless sensor networks that operate without a continuous sink presence, and discusses potential solutions like data protection through encryption and authentication. It concludes that new security challenges arise from features like intermittent connectivity, and that infrastructure-independent and new cryptographic techniques are needed to address issues in emerging wireless 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.

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 describes TrustedDB, a database system that uses trusted hardware to enable private queries on outsourced data. TrustedDB allows clients to execute SQL queries while preserving privacy and regulatory compliance by leveraging tamper-proof trusted hardware for sensitive query processing stages. This removes limitations of software-only encryption approaches. The system partitions queries into public and private components, executing the latter on secure hardware for better performance and lower costs than solely cryptographic approaches. Evaluation shows TrustedDB can support full-fledged databases on trusted hardware more cost-effectively than existing techniques.

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.
This document proposes a secure communication framework for embedded networking. The framework aims to be platform neutral and hardware independent. It incorporates a secured database containing all possible system events. Embedded systems can authenticate and access this database. The framework also protects the communication channel by encrypting transmissions, secure handshaking, and using self-adaptive frame structures. It references event indexes from the database rather than transmitting actual information. The database is dynamically recreated on each power-on to change event indexes and improve security. The framework is designed to be easily implemented using proven security technologies while providing modest protection for embedded network devices.
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 research paper that designed and implemented a Quality of Security Service (QoSS)-compliant Advanced Encryption Standard (AES) processor for use in multimedia applications. The processor uses a reconfigurable architecture that can provide up to 12 different AES cipher schemes with reasonable hardware costs. It allows users to specify security requirements through a security vector. Evaluation showed the QoSS-AES processor can provide high security for multimedia communications like MPEG video with low latency. Implementation on FPGAs demonstrated competitive speed, area and power performance compared to other FPGA-based AES designs.
Analyzing and Securing Data Transmission in Wireless Sensor Networks through ...ijtsrd
Wireless Sensor Networks are gaining popularity in various fields and areas. But these nodes are vulnerable as they are open networks and easily accessible. The major challenge is to have a secure data transmission between the nodes. To establish a secure transmission, we require a security scheme like a cryptographic algorithm, but this also requires a secure key distribution between nodes. The WSN’s have constraints like limited area, power and memory which restrict all the categories of cryptographic algorithm. Depending upon the criteria’s and constraints, cryptographic algorithm like Elliptic Curve Cryptography ECC is best suitable for WSN’s environment. ECC has a smaller key size, high security and less computation time which makes the node an efficient crypto system. In order to protect the security of data, we propose a novel secure transmission strategy based on Cryptography. In this design, we acquire sensitive information securely so as to make use of the advantage of encryption. Our approach deal with the weakness of limitation in sensor node resources and the security threats, it is suitable for stream data in sensor nodes. The simulation experiments also demonstrate that this approach is effective in transmitting sensitive data covertly with the characteristics of lower energy consumptions and invisibility. This paper describes the implementation of ECC cryptosystem for WSN for secure key and data transmission between the nodes.

Iaetsd secure data dissemination based onIaetsd Iaetsd
This document proposes a secure data dissemination protocol called Se-Drip for wireless sensor networks. Se-Drip uses a Merkle hash tree to securely disseminate data from a base station to sensor nodes in the network. The protocol has three phases: 1) initialization where the base station generates keys and loads them on nodes, 2) packet preprocessing where the base station constructs data packets and their authentication paths in a Merkle hash tree, and 3) packet verification where nodes verify received packets against the hash tree to authenticate the data. Se-Drip aims to securely disseminate data while being lightweight, robust to packet loss, and resistant to denial-of-service attacks.

AN ENERGY-EFFICIENT AND SCALABLE SLOTBASED PRIVACY HOMOMORPHIC ENCRYPTION SCH...ijassn
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.

This document describes a proposed system for enabling effective yet privacy-preserving fuzzy keyword search in cloud computing. It formalizes the problem of fuzzy keyword search over encrypted cloud data for the first time. The system uses edit distance to quantify keyword similarity and develops two techniques - wildcard-based and gram-based - to construct efficient fuzzy keyword sets. It then proposes a symbol-based trie-traverse searching scheme to match keywords and retrieve files. Security analysis shows the solution preserves privacy while allowing fuzzy searches.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

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.

2. 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.
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.

3. Modules Description
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
4. In this module, the energy cost and computation efficiency on the generation and verifications of the
certificates or signatures for security.
Attack resilience
In this module, the types of attacks that security protocol can protect against.
