【摘要】 为了增强EPS NAS层密钥推衍算法的灵活性和安全性,提出了一种解决方法,在EPS NAS层安全的鉴权过程中,增加UE对推衍算法的支持能力,在UE与HSS中增加推衍算法列表。该方法使得在认证过程中HSS能够根据需要选择不同的算法推衍密钥。更多还原

【Abstract】 To enhance the flexibility and security of the EPS(Evolved Packet System) NAS(Non-access Stratum) key drive algorithm,a method is proposed.During the EPS NAS authentication,UE′s capability of supporting the key drive algorithm is added,and the key drive algorithm lists are added in UE and HSS.This method makes HSS choose a key drive algorithm based on its requirement during the authentication.更多还原
