Abstract

A method and apparatus for ensuring the security of messages communicated on a network. The system employs different levels of security to ensure that communication integrity is not breached. A user must first enter a valid password to clear the access control subsystem. The sending user must also possess valid cryptographic information and belong to a particular organization and/or be located at a particular device in order to encrypt a plain text message that is to be transmitted over the network. The device and organization information, along with receiving user information specified by the sending user, will then be grouped into a header which will be appended to the outgoing encrypted message. In order to receive a transmitted message, a receiving user must be the particular receiving user and be part of the particular group specified by the sending user, and must be attempting to receive the communication at the device specified in the message header. If these conditions are satisfied, cryptographic information must be entered into the system in order to decrypt the message, resulting in the original plain text message.
