认证工作流:保护代理AI的系统方法

Authenticated Workflows: A Systems Approach to Protecting Agentic AI

Mohan Rajagopalan, Vinay Rao

AI总结:

本文提出认证工作流,通过密码学和运行时策略结合,实现企业代理AI的确定性安全,有效防护多种安全风险。

摘要:

代理AI系统自动化企业工作流,但现有防御措施——护栏、语义过滤器——是概率性的,经常被绕过。我们引入了认证工作流,这是首个完整的信任层,用于企业代理AI。安全归结为保护四个基本边界:提示、工具、数据和上下文。我们在每个边界跨越时强制执行意图(操作符合组织政策)和完整性(操作具有密码学认证),结合密码学消除攻击类别与运行时策略执行。这提供了确定性的安全——操作要么携带有效的密码学证明,要么被拒绝。我们引入了MAPL,一种针对AI的策略语言,动态表达代理约束,随着代理演变和调用上下文变化而扩展,通过分层组合与密码学认证的工作流依赖关系,将政策规模从O(log M + N)与O(M x N)规则相比。我们通过整合九个领先框架(MCP、A2A、OpenAI、Claude、LangChain、CrewAI、AutoGen、LlamaIndex、Haystack)的通用安全运行时,通过薄适配器实现实用性,无需任何协议修改。形式证明确立了完整性和正确性。实证验证显示,在174个测试用例中实现了100%召回率,零误报,保护了OWASP Top 10风险中的9个,完全缓解了两个高影响生产CVE。

英文摘要:

Agentic AI systems automate enterprise workflows but existing defenses--guardrails, semantic filters--are probabilistic and routinely bypassed. We introduce authenticated workflows, the first complete trust layer for enterprise agentic AI. Security reduces to protecting four fundamental boundaries: prompts, tools, data, and context. We enforce intent (operations satisfy organizational policies) and integrity (operations are cryptographically authentic) at every boundary crossing, combining cryptographic elimination of attack classes with runtime policy enforcement. This delivers deterministic security--operations either carry valid cryptographic proof or are rejected. We introduce MAPL, an AI-native policy language that expresses agentic constraints dynamically as agents evolve and invocation context changes, scaling as O(log M + N) policies versus O(M x N) rules through hierarchical composition with cryptographic attestations for workflow dependencies. We prove practicality through a universal security runtime integrating nine leading frameworks (MCP, A2A, OpenAI, Claude, LangChain, CrewAI, AutoGen, LlamaIndex, Haystack) through thin adapters requiring zero protocol modifications. Formal proofs establish completeness and soundness. Empirical validation shows 100% recall with zero false positives across 174 test cases, protection against 9 of 10 OWASP Top 10 risks, and complete mitigation of two high impact production CVEs.
