Abstract:
1. An apparatus comprising: a wireless transceiver to communicatively couple to personal area networks (PANs); a storage device, coupled to the wireless transceiver, to store a digital certificate that uniquely identifies a user; an authentication module, coupled to the wireless transceiver, to automatically log the user on to a first device within a first PAN using the digital certificate in response to the wireless transceiver communicatively coupling to the first PAN, and to automatically log the user on to a second device within a second PAN using the digital certificate in response to the wireless transceiver communicatively coupling to the second PAN; and an encryption module, coupled to the wireless transceiver, to provide an encryption service for the first device after the user is logged on to the first device, wherein providing the encryption service comprises receiving an encryption request from the first device, the encryption request comprising a message to be encrypted, encrypting the message using a private key associated with the user, and causing the wireless transceiver to send the encrypted message to the first device, wherein the first device transmits the encrypted message to a remote recipient without decrypting the encrypted message.
