Towards ubiquitous cooperative security

As computer and information systems are now more ubiquitous than humans, so too are the computer-to- computer threats to security and sabotage as compared to purely human-to-human. In everyday life we rely and maintain strong relationships in order to have better guarantees about personal security, as well as to be informed about potentially bad choices for relationships. This paper proposes some logical reasoning, architecture and protocols for providing similar cooperative security infrastructure for ubiquitous computer and information systems.
