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.
