A New Digital Signature Scheme

摘要

A new digital signature scheme based on EIGamal signature scheme and DSA is proposed. Some of the attacks against EIGamal scheme are discussed and how these attacks can be avoided in our scheme is also given. The proposed scheme is much more secure than EIGamal scheme. In the proposed scheme signatures are much shorter than in EIGamal scheme. This results in reduction in network load and hence reduction in communication cost.
