Abstract:
1. A wireless sensor network system, adapted for a medication information security environment, the wireless sensor network system comprising: a first sensor node, sending a request for registration and a user identification to a central node; the central node, generating and storing a first set of random number and a second set of random number when receiving the request for registration and the user identification, and sending the first set of random number and the second set of random number to the first sensor node and a second sensor node respectively, wherein the first sensor node encodes a password and a message for generating a cover-coded password and a first cover-coded message by using the Padgen function operation with the first set of random number and the second set of random number; wherein the first cover-coded message comprising a first least-bit cover-coded message and a first most-bit cover-coded message; and the first sensor node sending the cover-coded password and the first cover-coded message to the central node; wherein the central node using a cyclic redundancy check code for verifying whether the cover-coded password and the user identification matched to a stored data, when is matched the central node decoding the cover-coded password and the first cover-coded message using the first set of random number and the second set of random number, encoding the first message for generating a second cover-coded message using the first set of random number and the second set of random number; wherein the second cover-coded message comprising a second least-bit cover-coded password to the second sensor node; wherein the second sensor node verifying the cover-coded password and the user identification for matching, decoding the cover-coded password and the second cover-coded message using a Padgen operation with the first set of random number and the second set of random number.
