摘要：

PKI用证书管理公钥。无线网络设备的能量、计算能力和存储容量有限，限制了带证书的数字签名的应用。针对上述问题，利用布鲁姆过滤器技术，结合公钥密码体制，提出一种不带数字证书的、适用于无线移动场景的双向认证密钥协商方案，并对其进行性能分析和安全性分析。结果证明，该方案结合计数型布鲁姆过滤器技术，更容易实现用户与接入点的动态管理。

Abstract: PKI uses certificate to manage public key. The application of digital signature carrying certificate is restricted for the limited computing power and memory capacity of wireless terminal device. Aiming at this problem, this paper uses Bloom filter and combines with public key cryptography, proposes a scheme of mutual authentication and key exchange for WAP which is suitable for the environment of wireless, and makes an analysis of the performance and safety about the proposed scheme. Results prove that this scheme can make use of counting Bloom filter to implement the dynamic management of users and user points.

Key words: Bloom filter, public key, mutual authentication
