| 摘 要： | 分析了密钥交换协议的特点,提出了一种基于属性的密钥交换协议,能够更灵活地控制不同用户参与密钥交换的权限,该协议基于Sahai-Waters ABE体制,只需要一轮消息通信。研究了密钥交换协议的安全需求,应用＂敌手-挑战者＂游戏,提出了基于属性密钥交换协议的语义安全性定义,进一步在标准模型中证明了协议的安全性。

| Abstract: | With the extension of identity-based cryptography,the attribute-based encryption haas been used to control different authorities of decrypting a cipher-text among different users in a more flexible manner.Thus attribute-based encryption has become a hot research topic nowadays.With the development of attribute-based encryption,the attribute-based key exchange has also become a point which attracts a great deal of attention.The distinctive features of key exchange protocols are analyzed.An attribute-based ke... |
