A New API in Support of NDN Trust Schema

The decade-long experiences from developing applications over Named Data Networking (NDN) have taught us the importance of well-designed libraries that offer support to application developers to support data security. NDN trust schema provides a critical component in the NDN security support, however its implementation and support only started receiving significant attention in recent years. This paper first provides a summary of the existing API support for trust schema, then takes a step forward by developing a new trust schema API, named Envelope. Envelope addresses the application requirements by offering comprehensive trust schema functionalities, an easy-to-write schema language, and an extensible design. To demonstrate the usefulness of Envelope , we develop a blog application which uses Envelope to secure its data. Our results show that Envelope provides effective trust schema support for applications with acceptable overhead.
