Abstract: A secure messaging system and method includes 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. 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.

Abstract: A method of detecting hazardous conditions within an underground environment can include obtaining acceleration information at a plurality of communication nodes distributed throughout the underground environment and propagating the acceleration information among selected ones of the plurality of communication nodes to an analysis node. An indication of a hazardous condition within the underground environment can be identified from the acceleration information collected over a period of time. If an indicator is identified, a notification of the hazardous condition can be provided.
