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, the authors propose a novel secure key issuing scheme for P2P networks using IBC. They 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.
