摘要： 提出了一个基于自认证密码系统的短指定验证者签名方案。与其他指定验证者签名方案相比，该方案具有自认证密码系统的优点，既不需要证书对公钥显式认证，又避免了密钥托管问题。签名长度比较短，特别适用于带宽受限的场合。

Abstract: This paper proposes a short designated verifier signature scheme based on self-certified cryptosystem. Compared with other designated verifier signature schemes, this one takes the advantage of self-certified cryptosystem, without explicit authentication to public key by certificate and the key escrow problem. Since the signature’s size is short, it is particularly useful in circumstance where bandwidth is limited.

Key words: digital signature, elliptic curve, self-certified cryptosystem, designated verifier signature
