Secure Overlay Services (SOS)

Abstract : The goal of the Secure Overlay Services (SOS) project is to develop an infrastructure upon the existing, insecure Internet that allows an organization to install entities inside the network. An example of an entity is a military database that maintains timely or confidential information (e.g., intelligence). The SOS allows authorized users located anywhere in the Internet to communicate with the entity, and prevents unauthorized users from communicating with the entity. Furthermore, the SOS prevents unauthorized users from denying authorized users access to the entity.
