摘要：
Identity-based cryptography (IBC) is considered as a promising mechanism in the Internet of Things andad-hocnetworks, providing lightweight authentication and powerful access control. However, it suffers from two inherent problems, i.e. key escrow and the requirement of a secure channel, which are not always good properties in many realistic scenarios. Thus, an efficient key issuing protocol in a distributed setting without the assumption of the secure channel is needed. In this study, the authors give special attention to the IBC standardised inIEEE P1363and design a multi-party setup and key issuing protocol for it. Their protocol is proven to be malicious secure by simulation under weaker assumptions. Contrast to prior works that rely on a trusted party for key distribution or the strong assumption of a secure channel, they provide the first practical solution for the distributed architectures.
