Abstract
A system and method for securing information associates a party with a node that communicates messages over one or more channels based on a channel access privilege. One or more authorities sign a cryptographic authorization permit (CAP) to authorize the channel access privilege, which can be a write privilege or a read privilege. In one embodiment, the authorization for the channel access privilege is based on a public key issued by an authority and the CAP comprises a cryptographic certificate digitally signed by the authority.
