AI 中文摘要
隐形互联网项目（I2P）是一个支持安全和对抗性通信的去中心化对等网络，对网络安全和国家安全有重大影响。其全球拓扑结构由数千个独立的对等点选择决策产生，形成了一个以中心节点为主导的复杂结构，难以被外部观察。先前基于协议文档的模型无法捕捉真实行为。我们通过从生产代码中推导并在一个由六个路由器组成的地理分布测试平台上进行了三十天验证的扩展数学模型（EMM）来弥合这一差距。结果显示了有限的路由器可见性（约25%的节点）、相对论性层级分配、对快速层级隧道的强烈偏好以及高容量层级探索性隧道的过度代表。该模型准确预测了出现的拓扑不对称性，并定义了破坏隐私所需的对抗资源，为网络威慑和安全的去中心化网络设计提供了原则基础。
英文摘要
The Invisible Internet Project (I2P) is a decentralized, peer-to-peer network underpinning secure and adversarial communications with major implications for cybersecurity and national security. Its global topology emerges from thousands of independent peer-selection decisions, producing a hub-dominated, complex structure that resists external observation. Prior models based on protocol documentation failed to capture real-world behavior. We close this gap with an Extended Mathematical Model (EMM) derived from production code and validated on a six-router, geographically distributed testbed over thirty days. Results reveal limited router visibility (~25% of nodes), relativistic tier allocations, strong Fast-tier tunnel preference, and overrepresented High Capacity-tier exploratory tunnels. The model accurately predicts emergent topological asymmetries and defines the adversarial resources required to compromise privacy, providing a principled foundation for cyber deterrence and secure decentralized network design.
