Dynamic Group Communication Security

چکیده
I f multicast communication appears as the most eficient way to send data to a group of participants, it presents also more vulnerabilities to attacks and requires services such as authentication, integrity and confidentiality to transport data securely. In this papel; we present the protocol Baal’ as a scalable solution to group key inanagement problems and show how Baal resolves the user’s revocation problem. This protocol is based on decentralized group key management with only one key shared among group members. We use then Network Simulatol; ns-2, in order to evaluate the pe~ormance of our protocol in the case of group initialization, and compare it with SKDC approaches.

متن کاملSecure Group Key Management for Dynamic Sensor Networks
Problem statement: Key management is an important cryptographic technique for providing security in a dynamic environment of sensor networks. To provide a secure communication among a group of sensor nodes keys should established in an efficient manner. We introduced an efficient and dynamic key management system for dynamic sensor networks. Approach: We pre deployed some of the keying material...
متن کاملConstant Round Dynamic Group Key Agreement
We present a fully symmetric constant round authenticated group key agreement protocol in dynamic scenario. Our proposed scheme achieves forward secrecy and is provably secure under DDH assumption in the security model of Bresson et al. providing, we feel, better security guarantee than previously published results. The protocol is efficient in terms of both communication and computation power.
