FIA: Collaborative Research: A Content and Service Friendly Architecture with Intrinsic Security and Explicit Trust

今天的互联网承受着巨大的压力：使用模式日益多样化，对可信通信的迫切需求，以及越来越多的利益相关者必须协调才能提供互联网服务。该项目正在开发可表达的互联网体系结构(XIA)，这是一种潜在的新网络体系结构，基于几个关键原则。首先，XIA代表一个单一的网络，该网络为不同主体之间的通信提供内在支持，包括主机、内容、服务和未知的未来实体。对于每种类型的主体，夏都定义了一个窄腰，它规定了用于通信的API和网络通信机制。其次，夏依赖于内在安全的基础上，其中使用夏的各种自我认证标识符来保证通信的完整性和真实性。第三，XIA实现了灵活的上下文相关机制，用于在通信主体之间建立信任，弥合了人类和本质上安全的标识符之间的差距。最后，认识到互联网在我们社会中的核心作用，经济、政策和可用性方面的考虑在夏的设计中发挥了重要作用。该项目包括评估和改进网络与用户之间的接口的用户实验，以及分析技术设计决策与经济激励和公共政策之间关系的研究。该项目的结果将是关于潜在的未来网络体系结构的知识，该体系结构本质上是可信的，支持网络使用模型和网络技术的长期发展，并为网络参与者之间的交互提供明确的接口。该架构还将为包括用户、运营商和内容所有者在内的各种利益相关者提供更好的可见性和控制力。

Today's Internet is under enormous pressure: there is a growing diversity of use models, an urgent need for trustworthy communication, and a growing set of stakeholders who must coordinate to provide Internet services.The project is developing the eXpressive Internet Architecture (XIA), a potential new network architecture that is built around several key principles. First, XIA represents a single network that offers inherent support for communication between diverse principals including hosts, content, services, and unknown future entities. For each type of principal, XIA defines a narrow waist that dictates the API for communication and the network communication mechanisms. Second, XIA rests upon a foundation of intrinsic security in which the integrity and authenticity of communication is guaranteed using XIA's various self-certifying identifiers. Third, XIA enables flexible context-dependent mechanisms for establishing trust between the communicating principals, bridging the gap between human and intrinsically secure identifiers. Finally, recognizing the Internet's central role in our society, economic, policy, and usability considerations play a major role in XIA's design. The project includes user experiments to evaluate and refine the interface between the network and users, and studies that analyze the relationship between technical design decisions, and economic incentives and public policy.The outcome of the project will be knowledge about a potential future network architecture that is inherently trustworthy, supports long-term evolution of network use models and network technology, and provides explicit interfaces for interaction between network actors. The architecture will also enable greater visibility and control for various stakeholders, including users, ISPs, and content owners.
