摘要：Key issuing scheme focuses on the confidentiality maintained in using the secret key for communication in p2p networks. Identity based cryptography (IBC) was introduced into peer-to-peer (P2P) networks recently for identity verification and authentication purposes. However, current IBC-based solutions were not addressing the problem of secure private key issuing. In this paper we propose a novel secure key issuing scheme for P2P networks using IBC. We present an IBC infrastructure setup phase, a peer registration solution using Shamir’s (k, n) secret sharing scheme, and a secure key issuing scheme, which adopts key generate centre (KGC) and key privacy authorities (KPAs) to issue private keys to peers securely. This enables the IBC systems to be more acceptable and applicable in real-world P2P networks.
