A Forward Security Digital Signature Scheme

Abstract

Abstract: A new forward security digital signature scheme is presented based on ElGamal digital signature, and it can efficiently resist forge attack. The new scheme only increases a little computation comparing with ElGamal scheme, so it is a very useful digital signature scheme.

摘要： 在ElGamal数字签名的基础上构造了一种具有前向安全的数字签名方案，它能有效地抵抗伪造攻击。该方案与ElGamal签名相比只增加极小的计算量，因而是一种有效实用的签名方案。
