针对基于CAVE算法认证协议的侧信道分析方法
摘要：
一种针对基于CAVE算法认证协议的侧信道分析方法，通过采集cdmaOne的认证协议在移动设备上运行时产生的包含CAVE算法执行信息的功耗曲线，从功耗曲线中解析出CAVE算法执行参数，从而恢复出cdmaOne的认证协议所使用的密钥。本发明利用简单功耗分析和相关性功耗分析作为基础攻击工具，根据CAVE算法结构，构造综合攻击方法，通过该方法恢复cdmaOne认证协议中使用的密钥A-key。本方法适用于任何使用基于CAVE算法认证协议的密码系统。
摘要（英）：

The invention discloses a side channel analysis method based on a CAVE algorithm authentication protocol. A power consumption curve containing CAVE algorithm execution information generated when a cdmaOne authentication protocol runs on mobile equipment is collected, CAVE algorithm execution parameters are analyzed from the power consumption curve, and therefore a secret key used by the cdmaOne authentication protocol is recovered. Simple power consumption analysis and correlation power consumption analysis are used as basic attack tools, a comprehensive attack method is constructed accordingto a CAVE algorithm structure, and a secret key A-Key used in a cdmaOne authentication protocol is recovered through the method. The method is suitable for any password system using a CAVE-algorithm-based authentication protocol.
