本文描述了一种适用于移动互连网的数字签名方案。这种方案基于分布式计算体系,在签名者(或验证签名者)私有密钥和与通信对端共享的密钥不扩散的前提下实现签名方案。该方案解决了在只有弱计算能力的移动通信终端进行复杂签名和验证签名计算的问题。 This article describes a digital signature scheme for the mobile Internet. This approach is based on a distributed computing system that implements a signature scheme without the proliferation of the signer’s (or verifier’s signer’s) private key and the key shared with the correspondent’s peer. The solution solves the problem of complex signature and verification signature computation in mobile communication terminals with weak computing ability.
