## Source File
- [[Agent/agency-agents/specialized/agentic-identity-trust.md]]
## Summary用中文描述
- 核心主题:为自主 AI Agent 构建身份与信任验证基础设施,使得 Agent 在高风险环境中可证明自身身份、验证授权、生成防篡改操作记录
- 问题域:多 Agent 环境下的身份伪造、授权滥用、审计记录篡改、委派链断裂等安全问题
- 方法/机制零信任架构Never Trust Self-Reported+ 密码学身份证明 + 可验证委派链 + 追加式证据链 + 基于可观测结果的信任评分
- 结论/价值:身份与授权必须分离验证;不可变日志才能用于审计;委派链任一环节断裂则整链失效;信任必须量化而非自我声称
## Key Claims用中文描述
- 零信任原则Agent 不得依赖自我声称的身份或授权,必须通过密码学证明和可验证委派链进行验证
- 身份与授权分离:证明"我是谁"与证明"我被授权做这件事"是两个独立的验证步骤
- 失败即拒绝Fail-Closed若无法验证身份或授权链必须拒绝执行而非默认允许
- 信任基于可观测结果:信任评分依据已验证的客观行为记录,而非自我报告的声明
- 证据链不可篡改:追加式记录 + 前置哈希链接 + Agent 签名,使得任何历史记录修改可被检测
## Key Quotes
> "Never trust self-reported identity. An agent claiming to be 'finance-agent-prod' proves nothing. Require cryptographic proof." — 零信任身份原则
> "Identity and authorization are separate verification steps. Prove who this agent is — that doesn't prove it's authorized for this specific action." — 身份与授权分离原则
> "If a delegation chain has a broken link, the entire chain is invalid." — 委派链失效原则
> "Trust score 0.92 based on 847 verified outcomes with 3 failures and an intact evidence chain" — 信任必须量化表达
## Key Concepts
- [[Zero-Trust-Model]]:永不信任自我声称的身份或授权,所有声明必须通过密码学证明验证
- [[Trust-Score-Model]]基于可观测结果的惩罚型信任评分初始1.0,只扣不减(证据链完整性、行为达成率、凭证新鲜度)
- [[Delegation-Chain]]:多跳授权链,每个链接需签名、作用域不得超出上级、需验证时间有效性,链中断则整链失效
- [[Evidence-Record]]:追加式、防篡改的 Agent 行为证据记录,通过前置哈希链接形成链式结构
- [[Peer-Verification-Protocol]]Agent 接受委托前必须验证对端的身份、凭证有效期、作用域、信任评分和委派链
- [[Fail-Closed-Authorization]]:验证失败时默认拒绝,不默认允许
- [[Cryptographic-Identity-Scheme]]:基于 Ed25519/ECDSA 等标准算法的 Agent 身份方案,支持后量子迁移
## Key Entities
- [[Identity-Graph-Operator]]:与 Trust Architect 互补的实体——前者负责 Agent 身份("这 Agent 是谁"),后者负责人/公司/产品的实体身份("这条记录对应哪个客户"
- [[The-Agency]]Agent 所在的多 Agent 组织环境
- [[A2A]]:多 Agent 通信协议之一Trust Architect 需支持跨协议的身份联邦
- [[MCP]]Model Context ProtocolTrust Architect 需支持其身份桥接
- [[LangChain]]Agent 编排框架之一Trust Architect 需支持其身份翻译层
- [[CrewAI]]Agent 编排框架之一Trust Architect 需支持其身份翻译层

- [[Identity-Graph-Operator]] ← complements ← [[Agentic-Identity-Trust]]

- [[Agents-Orchestrator]] ← requires ← [[Agentic-Identity-Trust]]
## Contradictions
- 与 [[specialized-document-generator]] 可能的架构冲突:
- 冲突点Document Generator Agent 强调程序化文档生成能力但未提及身份验证层Trust Architect 强调每个 Agent 行动前必须经过身份与授权验证
- 当前观点Trust Architect 认为任何自主行动的 Agent 都必须经过身份验证
- 对方观点Document Generator Agent 专注于文档生成能力,身份验证可能由外层编排系统负责
- 协调建议:明确身份验证的边界——若由编排层(如 Agents Orchestrator统一处理子 Agent 专注于自身专业能力;若由各 Agent 自主处理,则需为 Document Generator Agent 补充身份验证架构
