摘要

5G协议的安全性相比4G有了较大的提升，其中鉴权算法也做了许多改进，然而5G USIM卡中的加密算法依旧受到侧信道分析技术的威胁.文章研究了5G AKA鉴权协议的流程和架构，分析了该协议在密钥生成阶段的脆弱性，针对商用5G USIM卡实施了相关性功耗分析，恢复出秘密参数，并据此实现了对5G USIM卡的复制、入网和鉴权测试，验证了其对侧信道分析技术的脆弱性.

Abstract

Compared with 4G

the security of 5G protocol has been greatly improved

and the authentication algorithms has also made many improvements. However

the encryption algorithms in 5G USIM card are still threatened by the side channel attack. The process and architecture of 5G AKA authentication protocol are studied

and the vulnerability of the protocol in the key generation phase is analyzed. The correlation power analysis is carried out for commercial 5G USIM cards

and the secret parameters are recovered. Based on this

the replication

network entry and authentication tests of 5G USIM cards are implemented

and the vulnerability of the anti-side channel analysis technology is verified.
