Abstract: With proxy multisignature, many original signers can delegate their signing power to a proxy signer in such a way that the proxy signer can sign any message on behalf of them. In blind signature, the signer cannot make a linkage between the blind signature and the identity of the requester. Therefore, they are easily applied in electronic commerce. Based on Schnorr signature scheme, a new proxy blind multisignature scheme was proposed. One proxy signer can generate a proxy blind multisignature on behalf of many original signers. This scheme satisfies the security properties of both the blind signature scheme and the proxy multisignature scheme. It has advantages such as low computation load, high efficiency and security, and that the length of signature does not increase when the new original signers join in.
Key words: proxy signature, blind signature, proxy blind signature, proxy blind multi-signature
摘要: 代理多重签名,即一个代理签名人可以同时代表多个原始签名人的利益在一个文件上签名;而盲签名方案,具有消息的内容对签名者是不可见的特性,且签名被接收者泄露后,签名者不能追踪签名。 代理多重签名和盲签名在电子商务和电子现金系统中有着广泛的应用。结合两种方案的特点,基于Schnorr签名体制,给出了一种新的代理多重盲签名方案,即一个代理签名人能够代表多个原始签名人进行代理盲签名。该方案具有计算量小、效率高和安全性强等优点,且签名长度不随原始签名人的增加而增长。
