A Principle for Cryptographic Protocols Beyond Security, Less Parameters

Zhengjun Cao


Almost cryptographic protocols are presented with security arguments. None of them, however, did explain why a protocol should like this, not like that. The reason is that there are short of any principles for designing and analyzing cryptographic protocols. In this paper, we put forth such a principle beyond security, called Less Parameters, which says that the involved parameters should be reduced as less as possible. Actually, the principle ensures a protocol better cost. In different scenarios, the principle is not easy to grasp. Intuitively, we advise to introduce public parameters as less as possible. In the light of the principle, we investigate some signatures. We believe the techniques developed in this paper will be helpful to better some cryptographic protocols.
