结合批签名中统一签名的思想,分别提出基于承诺方案和基于RSA这2类可截取签名的改进方案。改进方案中对部分消息进行统一处理,提高了签名和验证效率。在随机预言模型下,证明所提改进方案在适应性选择消息攻击下具有不可伪造性和隐私性。
Motivated by the idea of batch signatures
two variants of content extraction signature schemes based on commit vector and RSA respectively were presented.In the proposed schemes
the efficiency of signing and verification were improved by unifying certain message.The analysis show that the proposed schemes are existentially unforgeable under chosen message attacks in the random oracle model.
