摘　　要：针对当前信息栅格服务托管模式存在的安全性问题,提出了基于密文的可信托管服务框架。该框架通过使用挑战-应答协议,建立信息使用者和信息拥有者(提供者)之间信息传递的可信通道,使信息在整个传输过程中以密文形式存在,确保了信息的可信性。实现该框架需使用的关键技术包括无可信第三方参与的密钥分配机制和加密数据查询方法。A new credible trusted service framework based on ciphertext inquiry is proposed to deal with the problem of security in the mode of information grid service. Using the challenge-response protocol, it is possible to establish a credible channel of information transmission between users and providers. Thus, information can be transferred in cipher code. The key technical problems needed to be solved by this framework include the cipher key distribution mechanism in which the incredible third party participates and the way of inquiring encrypted information.
