Research ArticleOpen accessEvery word in the titleMESSAGE AUTHENTICATION CODE BASED SECURE GROUP KEY MANAGEMENT PROTOCOL FOR MOBILE AD HOC NETWORKST. Peer Meera Labbai, V. RajamaniA mobile ad hoc network is a group of nodes which are communicating with each other with the use of radio frequencies. When there is high movement of mobile nodes, the nodes find difficult to reach other nodes. If the data are exchanged between nodes when there is high mobility, the data may be lost in transit. Therefore the security … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,732 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAN EFFICIENT AUTONOMOUS KEY MANAGEMENT WITH REDUCED COMMUNICATION/COMPUTATION COSTS IN MOBILE AD HOC NETWORKM. Devi, S. Chenthur PandianA primary concern in Mobile Ad Hoc Networks (MANETs) is security. Secret sharing is an effective way to distribute a secret among n parties, where each party holds one piece of the secret. A number of key management schemes have been proposed for MANETs. However the secret sharing to control key hierarchy needs larger message transmission costs in many techniques. … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,783 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOverview on Key Distribution Primitives in Wireless Sensor NetworkM. Raghini, N. Uma Maheswari, R. VenkateshOwing to the security requirements of wireless sensor network, the background of Wireless Sensor Network (WSN) is to be analyzed with different threats and attack models. Physical compromising of sensor nodes by an adversary is an emerging problem in sensor network and accordingly, it is necessary to provide an environment with efficient key management techniques due to resource constraints on … …Journal of Computer Science, Vol. 9, Issue 5 · 17 May 2013 · 6,183 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Enhanced and Cost Effective Group Key Management Scheme for Multicast NetworkSaravana Kumar Muthusamy, Purusothaman Thiyagarajan, Lavanya SelvarajKey management plays a vital role in the data communications. The proposed scheme is a key management scheme that provides more efficient and secure methods for key generation and utilization. Enhanced and cost effective key management scheme achieves a secure communication between the members within the group-based network. In this scheme, the group key is generated only once which is … …Journal of Computer Science, Vol. 9, Issue 4 · 10 May 2013 · 6,395 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRouting Based Data Security in Mobile Ad Hoc Network Using Group Key ManagementE. Mohanraj, K. DuraiswamyProblem statement: A mobile ad-hoc network (MANET) is a self-organizing system of mobile devices followed an infrastructure less framework associated by wireless links. In MANET, there is a possibility of packet data to get lost or hacked by an attacker. So, to improve a secure communication over MANET from attackers, several techniques have been developed. The previous work developed to … …Journal of Computer Science, Vol. 8, Issue 10 · 29 Aug 2012 · 6,700 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEfficient Star Topology based Multicast Key Management AlgorithmK. Saravanan, T. PurusothamanProblem statement: Secure group communication is very important for many applications such as internet pay sites. It provides efficient delivery of identical data to only the customers in the group. In large and dynamic multicast groups, the group keys of members have to be changed frequently whenever the member leaves or joins. A common method is to apply a symmetric … …Journal of Computer Science, Vol. 8, Issue 6 · 22 Mar 2012 · 7,350 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSecure Packet Encryption and Key Exchange System in Mobile Ad hoc NerworkSudhakar Sengan, S. Chenthur PandianProblem statement: Mobile Ad-hoc Network is infrastructureless network supported by no fixed trusted infrastructure. The packets had a chance to drop or hacked by eavesdropper during transmission. So, encryption method is required for sending and receiving packet in secret manner. Approach: In this approach, the block and key size had been increased by 256 bits. When compared to Rijndael algorithm, … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,391 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComputation of Private Key Based on Divide-By-Prime for Luc CryptosystemsZulkarnain Md Ali, Nawara Makhzoum Alhassan MakhzoumProblem statement: One of the public key cryptosystem is Luc cryptosystems. This system used Lucas Function for encryption and decryption process. Lucas Function is a special form of second-order linear recurrence relation. An encyption process is used to encrypt an original message to ciphertext by using public key. A decryption process is the process to decrypt a ciphertext into original … …Journal of Computer Science, Vol. 8, Issue 4 · 1 Feb 2012 · 7,069 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDistribution Key in Eight Bit's Color Image AlgorithmHamdi A. Al-Omari, Malek M. Al-Nawashi, Mohammed J. BawanehProblem statement: The networked multimedia systems have glorified the necessity for image copyright protection. To solve such problem an invisible structure called watermarking is added to an 8-bits color image in aim to mark it. The structure can be added by selecting bits under certain conditions; a few pixels of correspondence between the image and the ASSCI code. Approach: In … …Journal of Computer Science, Vol. 8, Issue 1 · 25 Oct 2011 · 6,995 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Effective Contributory Re-Keying Approach to Compute Conference KeyD. Thilagavathy, M. RajaramProblem statement: With the explosive growth of and internet and web applications many emerging group-oriented distributed applications such as tele/video-conferencing, multiplayer games are based on group communication model that need security services such as privacy and data integrity Hence a secure distributed group key agreement is required to establish and authenticate a common group key for secure and private communication. … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,646 accessesView PDFCite
