A Principle for Cryptographic Protocols Beyond Security, Less Parameters
Zhengjun Cao
Abstract: 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.
