中文摘要：

针对身份基加密方案效率和安全性不高的问题,利用＂双胞胎＂技术,提出了一个加密时只需使用一次配对的新方案.研究结果表明,该方案可以在随机预言模型下紧规约到标准难题,是具有适应性选择密文安全的身份基加密方案.

英文摘要：

This paper presented an efficient and secure identity-based encryption scheme.Compared to the previous scheme,it has the advantage of security or efficiency.This new scheme can achieve adaptive CCA2-security under BDH assumption with tight reduction.The construction was made by use of the ＂Twin Diffie-Hellman＂ technique proposed by Cash et al,only requiring one pairing computation during the encryption procedure.
