| 摘 要： | 提出一个认证密钥交换协议AKE-1。与已有的协议相比，AKE-1效率较高。基于随机预言假设和CDH假设，该协议被证明在eCK07模型下是安全的。AKE-1使用的技术是Cash, Kiltz和Shoup最近提出的陷门测试。基于AKE-1给出一轮的变体(满足只有一个实体在线)和三轮的变体(提供密钥确认属性)以满足不同的应用。

| Abstract: | This paper presents an Authenticated Key Exchange(AKE) protocol, named AKE-1. Compared with previous protocols, the proposal is more efficient and proven to be safe in newly enhanced Canetti-Krawczyk(eCK07) model under the random oracle assumption and the Computational Diffie-Hellman(CDH) assumption. It uses a technique named trapdoor test, recently proposed by Cash, Kiltz and Shoup. In addition, it presents a one-pass variant (for only one entity on line) and three-pass variant (providing key confirmation) of AKE-1 for different applications. |
