中文摘要：
为了避免基于身份密码系统中的秘钥托管问题，同时不需要证书进行公钥的认证，出现了无证书密码系统。该文基于双线性对提出一个新的无证书签名方案。方案中签名算法简单的不需要任何对的计算，验证算法仅仅需要三个对的计算，并且不需要使用特殊的哈希函数。与已知所有的方案相比，所提的方案在计算代价上更加有效。
英文摘要：
Due to eliminating the inherent key escrow in identity-based cryptosystem and yet not needing certificates to guarantee the authenticity of public keys, the concept of certificateless public key cryptosystem is introduced. In this paper, a new certificateless signature scheme based on bilinear pairings is present. The signing algorithm of the proposed scheme is very simple and does not require any pairing computation, and the verification algorithm only needs three pairings computation. Furthermore, the scheme does not need special hash function. Our proposed scheme is more efficient than all knowing schemes in terms of computation overhead.
