Implementing a Secure Key Issuing Scheme for Communication in P2P Networks

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.
