中文摘要：
该文在不经意传输和隐藏证书的基础上提出了隐藏认证的不经意传输,利用双线性对构造了一个具体方案.解决了对于不经意传输的基于标准属性证书的访问控制可能暴露接收者的某些敏感信息问题.该方案有如下特点：只有持有特定属性证书的接收者才能打开其所选择的消息,而接收者不需要向发送者提供任何证书.发送者不能确定接收者是否能够打开消息也不能确定接收者打开的是哪些消息.利用随机问答器模型,在BDH假设及CT-CDH假设下证明了该方案的安全性.
英文摘要：
Hidden authentication oblivious transfer based on k-out-of-n oblivious transfer and hidden credentials is proposed which solved the problem that standard certificated-based access control to oblivious transfer may exposure some sensitive information of the receiver. The scheme proposed has the property that only the receiver who has the required attribute credentials can open the message it chooses and the receiver need not provide to the sender any credentials. The sender can not decide whether the receiver can open the messages or not and the sender can not know which messages that the receiver acquires also. The security in the random oracle model is proved under the BDH assumption and the CT-CDH assumption.
