Google DeepMind 推出 AlphaProof Code，深度验证 Signal 协议代码
原标题：Introducing AlphaProof Code: a breakthrough in verifying complex software at depth
AI 摘要
Google DeepMind 发布 AlphaProof Code，一个多 LLM 智能体框架，用于对复杂软件进行深度形式化验证。研究人员用该框架对 Signal 加密协议的实际代码进行数学证明，验证了消息在设备临时被攻破前后仍受保护等关键安全属性，耗时仅四周，而传统专家团队通常需要数年。这是 AI 首次以如此深度形式化验证广泛部署的加密协议，也是该协议实现首次被任何方法形式化验证；团队还通过重新引入两个已修复的真实漏洞，确认系统能识别不安全代码。
