针对智能体互联网中注册、身份信任与能力发现缺失的问题，提出分层分布式信任发现架构，实现可扩展注册与解析，实验验证其低延迟和高吞吐性能。
AI 中文摘要
智能体互联网有望使大量自主智能体能够在异构平台之间相互发现、验证和协作。然而，当前的智能体协议主要解决工具调用和智能体间通信问题，而可扩展的智能体注册、可信身份识别和面向能力的发现在很大程度上仍未解决。为解决这一问题，本文提出了一种面向智能体互联网的可扩展信任发现架构。该架构采用分层分布式设计，由三层组成：Agent Root（智能体根节点）负责可信注册表治理，Agent Registry（智能体注册表）负责智能体注册和元数据发布，Agent Resolver（智能体解析器）负责分布式能力发现和信任感知解析。该架构进一步引入了一种基于注册表后缀锚定的复合身份方案，将智能体原生标识符与可信注册表后缀绑定，以生成全局可发现的身份。它还结合了双证书和多级认证机制，以增强智能体之间的身份信任。我们实现了一个原型，并通过大规模智能体注册和解析实验对其进行了评估。该原型实现了平均58毫秒的注册延迟和平均25毫秒的发现延迟，并支持每秒超过19,000个注册请求和每秒超过29,000个智能体发现请求。这些结果证明了所提出架构的可行性，为智能体互联网中可扩展且身份可信的智能体生态系统提供了一种实用方法。
英文摘要
The Internet of Agents is expected to enable large numbers of autonomous agents to discover, verify, and collaborate with each other across heterogeneous platforms. However, current agent protocols mainly address tool invocation and inter-agent communication, leaving scalable agent registration, trustworthy identification, and capability-oriented discovery largely unresolved. To address this, this paper proposes a scalable trust discovery architecture for the Internet of Agents. The proposed architecture adopts a hierarchical and distributed design consisting of three layers: Agent Root for trusted registry governance, Agent Registry for agent registration and metadata publication, and Agent Resolver for distributed capability discovery and trust-aware resolution. The architecture further introduces a registry-suffix-anchored composite identity scheme, which binds an agent native identifier to a trusted registry suffix to generate a globally discoverable identity. It also incorporates a dual-certificate and multi-level authentication mechanism to strengthen identity trust among agents. We implement a prototype and evaluate it through large-scale agent registration and resolution experiments. The prototype achieves an average registration latency of 58ms and an average discovery latency of 25ms, and it supports more than 19,000 registration requests per second and more than 29,000 agent discovery requests per second. These results demonstrate the feasibility of the proposed architecture, providing a practical approach toward scalable and identity-trusted agent ecosystems in the Internet of Agents.
