Group Key Management in Wireless Networks Using Session Keys

Abstract

Recent developments in the field of wireless networks have led to the phase where it has now become important to offer the members connected in a wireless network with a secure and efficient group key management system for accessing numerous services. A secure group key agreement protocol designed for multicast communications using short life span session keys [5] is proposed in this paper. Our proposed work guarantees key and data authenticity among the group members, and data confidentiality of group messages in addition to the properties of forward and backward secrecy. The group key is collaboratively established by combining the keys of all authenticated members, which helps in maintaining the communication and computation transparency among the group members.
