A Secure Group Communication and Rekeying using Rabin’s Squaring Trapdoor Function in Multicasting
In today‟s world of internet, secure communication among group of members has become vital, where multicasting plays an important role. In secure multicasting, security and scalability are the two important checks. Sometimes there is tradeoff between security and scalability. In order to transmit the data in a secure and scalable way, a suitable key management protocol should be implemented whi...
متن کاملReducing Overhead on Double Rekeying in Secure Group Communication
Nowadays networks require flexible dynamic group communication with the internet. When we develop these systems on multicast communication framework, various types of security threat occurs .As a result construction of secure group communication that protects users from intrusion and eavesdropping are very important. In this paper, we propose an efficient key distribution method for a secure gr...
متن کاملScalable balanced batch rekeying for secure group communication
Secure group communication is important for applications such as pay-per-view. Other authors have proposed the key tree approach to distribute a shared group key in a way such that the rekeying cost scales linearly with the logarithm of the group size for a join or depart request. The efficiency of the key tree approach depends critically on whether the key tree remains balanced. Periodic rebal...
متن کاملA Feebly Secure Trapdoor Function
In 1992, A. Hiltgen [1] provided the first constructions of provably (slightly) secure cryptographic primitives, namely feebly one-way functions. These functions are provably harder to invert than to compute, but the complexity (viewed as circuit complexity over circuits with arbitrary binary gates) is amplified by a constant factor only (with the factor approaching 2). In traditional cryptogra...
متن کاملSecure Group Communication with Self-healing and Rekeying in Wireless Sensor Networks
We have developed a self-healing key distribution scheme for secure multicast group communications for wireless sensor network environment. We present a strategy for securely distributing rekeying messages and specify techniques for joining and leaving a group. Access control in multicast system is usually achieved by encrypting the content using an encryption key, known as the group key (sessi...
