摘要： 时间戳能为电子文件或电子交易提供准确的时间证明。该文在时间戳相对认证和时间戳绝对认证2种机制的基础上，提出一种新型的基于椭圆曲线盲签名的安全数字时间戳方案，该方案能有效解决前向时间伪造，防止签名者和TSS合谋作假所引起的后向时间伪造。

Abstract: Time-stamping provides accurate time for E-document or E-transaction to prove. This paper analyzes the present scheme based on relative temporal authentication and absolute temporal authentication. A new scheme for secure digital time-stamping is proposed based on Elliptic Curve Cryptography(ECC) blind signature, which can effectively prevent the forward forgery, and prevent the backword forgery which is caused by signaturer and TSS ploting.

Key words: time-stamping, Elliptic Curve Cryptography(ECC), blind signature, time-stamping service
