Non-interactive two-channel message authentication based on hybrid-collision resistant hash functions
Atefeh Mashatan, Douglas R. Stinson · IET Information Security · 2007
The problem of non-interactive message authentication using an insecure broadband channel and an authenticated narrow-band channel is considered. This problem has been considered in the context of ad hoc networks, where it is assumed that there is neither a secret key shared among the two parties nor a public-key infrastructure in place. A formal framework for protocols of this type is presented, along with a new protocol which is as efficient as the best previous protocols. The security of the proposed protocol is based on a new property of hash functions called ‘hybrid-collision resistance’.
