基于AKA的轻量级天地一体化网络终端接入认证方案

LIGHTWEIGHT SPACE-GROUND INTEGRATED NETWORK TERMINAL ACCESSAUTHENTICATION SCHEME BASED ON AKA

针对认证与密钥协商(AKA)协议接入认证方案中存在随机数明文传输、接入点存储成本过高和认证所需的比特通信量大等问题,提出一种轻量级的AKA协议加密接入认证方案。该方案用轻量级的密码算法ZUC加密需要传输的信息,调整信息传输的次序,引入哈希链技术,提高接入认证安全性的同时,减少了通信次数和存储负担,能够更好地适用于计算能力、存储空间、电功率等属性受限、信道带宽受限的天地一体化网络环境。

In the view of the problems of plain text transmission of random numbers,high storage cost of access points and large amount of bit communication required for authentication in authentication and key agreement(AKA)protocol access authentication scheme,a lightweight AKA protocol encryption access authentication scheme is proposed.The scheme used a lightweight cryptographic algorithm ZUC to encrypt the information needed to be transmitted,adjusted the order of transmission,and introduced Hash chain technology,which improved the security of access authentication and reduced the communication times and storage burden.The scheme could be better applied to the space-ground integrated network environment with limited computing capacity,storage space,power and channel bandwidth.
