摘　　要：属性加密技术的核心是通过定义基于属性的访问策略,实现该策略对加解密的控制。本文提出了基于密文分离的属性加密方案,通过引入密文服务中心,对密文进行分离,提高了加密效率,并对该方案进行了安全性分析。通过分析可知,该方案提高了密文通信的安全性、机密性、完整性。The core of encryption technology is to realize the control of encryption and decryption by defining the attribute-based access strategy. This paper puts forward an encryption scheme based on ciphertext separation,where a ciphertext service center is introduced to separate the ciphertext,thus to improve the efficiency of encryption. Also,security analysis of the scheme is presented here,and the result shows that the scheme has improved the security confidentiality and integrity of ciphertext communication.
