设计全球身份验证基础架构

Designing a Global Authentication Infrastructure

Stephanos Matsumoto, Raphael M. Reischuk, Pawel Szalachowski, Tiffany Hyun-Jin Kim, Adrian Perrig

摘要:

我们解决的问题,扩展认证的命名,路由和最终实体认证的全球环境中,认证策略和用户的信任根集有很大的不同。当前的名称(DNSSEC)、路由(BGPSEC)和终端实体证书(TLS)认证机制不支持认证策略的共存,在受到威胁时会影响整个互联网,无法有效更新信任根信息,并且无法为用户提供灵活的信任决策能力。我们提出了一个可扩展的身份验证基础设施的下一代信任(SAINT),互联网划分成具有共同的,本地的信任根组,并隔离的影响妥协的信任根。SAINT要求具有直接路由连接的组相互交叉签名以进行身份验证,从而允许不同的身份验证策略,同时保持所有实体的全局可验证性。SAINT使信任根管理成为网络架构的核心部分,使信任根在几秒钟内更新,并允许用户做出灵活的信任决策。SAINT的运行不会带来显著的性能损失,并且可以与现有基础设施一起部署。

英文摘要:

We address the problem of scaling authentication for naming, routing, and end-entity certification to a global environment in which authentication policies and users' sets of trust roots vary widely. The current mechanisms for authenticating names (DNSSEC), routes (BGPSEC), and end-entity certificates (TLS) do not support a coexistence of authentication policies, affect the entire Internet when compromised, cannot update trust root information efficiently, and do not provide users with the ability to make flexible trust decisions. We propose a Scalable Authentication Infrastructure for Next-generation Trust (SAINT), which partitions the Internet into groups with common, local trust roots, and isolates the effects of a compromised trust root. SAINT requires groups with direct routing connections to cross-sign each other for authentication purposes, allowing diverse authentication policies while keeping all entities globally verifiable. SAINT makes trust root management a central part of the network architecture, enabling trust root updates within seconds and allowing users to make flexible trust decisions. SAINT operates without a significant performance penalty and can be deployed alongside existing infrastructures.
