摘要: 针对现有无线医疗传感器网络环境下身份认证协议在登录和密码更新阶段效率低下的问题,提出了一种基于椭圆曲线加密的身份认证协议.该协议可快速检测不正确的输入,将Hash函数与椭圆曲线加密算法相结合,使登录和密码更新阶段更有效.通过形式化分析工具BAN逻辑和仿真实验对该协议进行安全及性能分析,发现其可以抵御常见的攻击,如仿冒、重放、在线或离线密码猜测等,同时在性能上也符合无线医疗传感器网络的应用需求.

Abstract: Due to the inefficiency of the existing identity authentication protocol during the login and password update phase in the existing wireless medical sensor network environment, an elliptic curve cryptosystem based authentication protocol suing smart card was presented. The proposed protocol can quickly detect incorrect inputs. The proposed protocol combines the Hash function with the elliptic curve encryption algorithm, which makes its login and password update phases more efficient. Finally, using the BAN logic analysis, it is given that the proposed scheme is more secure than other protocols. The proposed protocol's computing performance and communication costs is also superior to other related authentication protocols.
