Secure Sharing Based on Group Key Transfer Protocol for Group Communications

چکیده
Key transfer protocols needs key generation center (KGC) to select and transport session keys to all communication entities secretly, that are mutually trusted. Often, during registration each entity shares a session keys that are encrypted under another secret key by the KGC. In this paper based on secret sharing scheme, we propose an authenticated key transfer protocol that once KGC can broadcast information of group key to all group members. Therefore only group members can recover the group key. The group key cannot recover by the unauthorized users. The confidentiality of this transformation is information theoretically secure. We also provide authentication for group key transportation.

Secure Key Transfer Protocol Based on Secret Sharing for Group Communications
Group key establishment is an important mechanism to construct a common session key for group communications. Conventional group key establishment protocols use an on-line trusted key generation center (KGC) to transfer the group key for each participant in each session. However, this approach requires that a trusted server be set up, and it incurs communication overhead costs. In this article,...
متن کاملOn the Security of an Authenticated Group Key Transfer Protocol Based on Secret Sharing
Group key transfer protocols allow multiple parties to share a common secret key. They rely on a mutually trusted key generation center (KGC) that selects the key and securely distributes it to the authorized participants. Recently, Sun et al. proposed an authenticated group key transfer protocol based on secret sharing that they claim to be secure. We show that this is false: the protocol is s...
متن کاملA novel Group Key Transfer Protocol
Group key transfer protocols depend on a mutually trusted key generation center (KGC) to transport the group key to all group members secretly. This approach requires that a trusted sever be set up, and it incurs communication overhead costs. In addition, the existing group key transfer protocols based on secret sharing all use threshold schemes that need to compute a -degree interpolating poly...
متن کاملProvably secure and efficient identity-based key agreement protocol for independent PKGs using ECC
Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...
متن کاملComputation-efficient key establishment in wireless group communications
Efficient key establishment is an important problem for secure group communications. The communication and storage complexity of group key establishment problem has been studied extensively. In this paper, we propose a new group key establishment protocol whose computation complexity is significantly reduced. Instead of using classic secret sharing, the protocol only employs a linear secret sha...
