Software development in distributed computation is complicated by the extra overhead of communication between connected, dispersed hosts in dynamically changing, multiple administrative domains. Many disparate technologies exist for trust management, authentication, secure communication channels, and service discovery, but composing all of these elements into a single system can outweigh principal development efforts. The NYU Disco Switchboard consolidates these connectivity issues into a single convenient, extensible architecture, providing an abstraction for managing secure, host-pair communication with connection monitoring facilities. Switchboard extends the secure authenticated communication channel abstraction provided by standard interfaces such as SSLTLS with mechanisms to support trust management, key sharing, service discovery, and connection liveness and monitoring. We present an extensible architecture which is particularly useful in dynamically changing, distributed coalition environments. Applications that utilize Switchboard benefit from the availability of authentication, trust management, cryptography, and discovery, while retaining the simplicity of a common interface.
