【摘要】 针对第三代移动通信系统(3G)中采用的认证与密钥协商(AKA)协议存在安全漏洞和密钥管理困难等问题,采用基于椭圆曲线密码(ECC)和公钥体制协商会话密钥、对称加密算法加密消息的方法,提出了一种应用于3G业务中的改进协议。该协议不仅有效克服了AKA协议中存在的各种缺陷,避免了复杂的密钥管理难题,而且相比其他协议更简单容易,具有实际应用性。更多还原

【Abstract】 To overcome the shortages of security flaws and secret key management in the Authentication and Key Agreement(AKA) protocol for the third mobile communication system,an improved protocol was proposed.It employed Elliptic Curve Cryptography(ECC) and public key to harmonize session key and symmetric encipherment algorithm to encrypt messages.The protocol not only overcomes the existed deficiencies in the AKA including how to manage secret key,but is more applicable than the others for its simple operation and easy to use.更多还原
