- Abstract
Identity‐based cryptography (IBC) is considered as a promising mechanism in the Internet of Things and ad‐hoc networks, 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 in IEEE P1363 and 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.
