Thwarting Sybil Attack using ElGamal Algorithm
نویسندگان
چکیده
MANET is an independent and infrastructureless network comprising of self configurable mobile nodes connected via wireless links. MANET is susceptible to various attacks because of some loopholes present in MANET like dynamic topology, zero central administration, limited physical security etc. MANET is prone to numerous malicious attacks one such attack among them is SYBIL ATTACK. In Sybil attack multiple identities are presented by a single physical node. This attack has serious impact on network functionality. In this paper principle focus is on preventing Sybil attacks using ElGamal algorithm. The concept of ElGamal algorithm has been used in this paper so as to deal with Sybil attacks.

متن کاملThwarting Attackers in the Wireless Networks without Trusted Authorities
Due to the broadcast nature of the wireless medium, wireless networks are especially vulnerable to Sybil attacks, where a malicious node illegitimately claims a large number of identities and thus depletes system resources. A wireless sensor network consists of many sensor nodes which are deployed to monitor physical or environmental conditions and to pass the collected data to a base station. ...
متن کاملSignal and Time Based Fuzzy Cluster Scheme to Detect Sybil Attack in VANET
Security is an important issue in the VANET environment and the Sybil attack affects it the most. In Sybil attack a node illegally claims itself as a legitimate node using multiple identities. This paper systematically analyses about Sybil attack and its effect in the VANET. We establish a Signal and Time clustering (STC) algorithm to detect the Sybil attack in VANET. The scheme provides a low ...
