ENHANCED MESSAGE SECURITY

摘要

A secure messaging system and method. The method can include the steps of receiving an encrypted message, the message having been encrypted using a token of a corresponding pervasive device; wirelessly verifying the presence of the pervasive device; and, if the presence can be verified, decrypting the message using the token. The verification step can include the steps of establishing a wireless link with the pervasive device; and, querying the pervasive device over the wireless link. In particular, the establishing step can include the step of establishing a Bluetooth link with the pervasive device. Furthermore, the querying step can include the step of requesting geographic coordinates which locate the pervasive device.
