摘要
提出一种将椭圆曲线密码系统身份认证协议应用GSM网络上进行身份认证的控制方法.采用CA证书机制,应用离线获取证书,在线相互认证提高GSM网络系统安全性.应用无求逆数字签名方案实现CA认证,简化了计算复杂度,并通过通讯双方数字签名实现不可抵赖性,最后给出了协议安全分析.提出的认证协议具有保密性高及传输参数少的优点,较容易在无线移动通讯系统软硬件中实现.
Identity authentication in GSM network environment is proposed by using identity authentication protocol based on elliptic curve cryptosysterm. Applying CA mechanism, obtaining the certification offline, the security of the GSM network system is enhunced by authenticating each other online. The CA mechanism is executed by using the no-inverse digital signature scheme, and the complexity of computing is reduced. The mutual signatures of communication realize the nonrepudiation. The security analysis of the protocol is given. The advantages of this protocol are higher security, less parameters of transmission and easier to realize by the hardware of mobile wireless communication system.
