Design and implementation of secure data aggregation in wireless sensor networks

International journal of latest trends in engineering and technology, 2016

These networks are used in both military and civilian applications. Limited use of the battery power is the key challenge in all types of remote sensing applications. In most of the real time applications, sensor nodes are deployed in the open and remote environments. While data aggregation can assure energy conservation, authenticity and integrity are not guaranteed. As such, wireless sensor networks are highly vulnerable to security threats; methods are needed for assuring the secure transmission with minimal energy requirements. Numerous cryptographic algorithms are proposed by several researchers to control malicious behavior in the wireless medium. But each algorithm needs the complex hardware resources to execute it. Because of the limited resources in sensor devices, it is impossible to use conventional cryptographic algorithms to ensure security. Key management and cryptographic algorithms lead to high computation cost in the individual sensors. Key exchange and new key generation lead to communication overhead, and hence it increases energy consumption in the overall network.

Client-Side Encryption in Cloud Storage Using Lagrange Interpolation and Pairing Based Cryptography

Security and the privacy are the main concern to establish the trust cloud service; a solution is needed to achieve confidentiality and integrity of the user data. Many modern cryptographic techniques are available to protect the user’s data in the cloud storage. In this research, we proposed an asymmetric cryptographic technique for securing the data which encrypts the original message before placing it in the cloud storage. The proposed algorithm is providing the following securities: security in transit and security at rest. Our proposed protocol equipped with the security parameters like confidentiality, authentication.

An Extended Identity Based Authenticated Asymmetric Group Key Agreement Protocol

[26] proposed a new asymmetric group key agreement protocol allowing a set of users to negotiate a common encryption key accessible by any user, and each user holds her respective decryption key. This enables the confidential message communication among group users, and grants any outsider to send message to the group. In this paper, an authenticated asymmetric group key agreement protocol is proposed, which offers security against active as well as passive attacks. Proposed protocol uses broadcast encryption mechanism without relying on the trusted dealer to distribute the secret key. An identity based feature is included in the protocol to provide authentication.

Current Trends in Group Key Management

Various network applications require sending data onto one or many members, maintaining security ... more Various network applications require sending data onto one or many members, maintaining security in the large groups is one of the major obstacles for controlling access. Unfortunately, IP multicast is not providing any security over the group communication. Group key management is a fundamental mechanism for secured multicast. This paper presents relevant group key management protocols. Then, we compared them against some pertinent performance criteria. Finally, we discuss the new research directions in group key management. Keywords-Multicast; group key management; security member driven; time driven. I. INTRODUCTION With rapid growth in the internet, people using the group communication in applications such as paying TV, transmission of video and audio, updating software, military applications, video games etc. In recent decades, the focus is mainly on the security issues involved in the group communication. When the group uses the unicast communication, one sender is sending the data stream onto one group member. In multicasting, the group member is sending the data onto other group members. Security is main focused area in group communication. Group key management is the fundamental mechanism provides the security in group communication. In this, security is achieved by sharing a common key among the group members. The message packets, those are going to transmit should be encrypted with the shared key. Group key management is mainly focusing on the key generation and distribution of key among the group members. All the group members should participate in the secure distribution, creation and revocation of the keys [1]. The communication session in group key management is managed by two entities: Group Controller (GC), responsible for key generation, distribution and rekeying for membership change and Key Server (KS), responsible for maintaining the keys and distributing the keys.

In this paper we examined two things vitality and security.1) a energyefficient technique with excess traffic (EEHRT) in the zone-based directing for Wireless Sensor systems. In this procedure, multihop directing is performed dependent on the rest of the vitality of the hubs. A short time later, it performs position-based directing without the requirement for the hubs to know their individual position. The fundamental goal of this paper is to deal with the repetitive parcels produced in zone-based steering utilizing short signal messages. Hubs of lower zones course the information of the higher zone to base station (BS) with a base number of bounces and use just those hubs on the way which are vitality productive and found nearer to BS. Also, the source hub is recognized b...

Secure Message Transmission using Lagrange Polynomial Interpolation and Huffman Coding

International Journal of Computer Applications, 2012

The message is viewed as a polynomial of degree n where n is kept secret and transmitted to the receiver's side using the concept of a digital envelope. As any nth degree polynomial is uniquely determined by n+1 points, n +1 points are communicated to the other side, where the polynomial and hence the message is reconstructed. Padding of length m is added to the message to overcome the message length issue. Although any coding scheme may be used, in this paper Huffman coding is used for converting the plaintext into binary form. Finally, the proposed algorithm is compared with the performance of RSA algorithm and found to be efficient.
