WIRELESS SENSOR NETWORK AND CENTRAL NODE DEVICE THEREOF

摘要

The invention is directed to a wireless sensor network system. The wireless sensor network system is adapted for a medication information security environment, and the wireless sensor network system comprising a first sensor node, a second sensor node and a central node. The first sensor node sends a request for registration and a user identification. The central node generates and stores a first set of random number and a second set of random number when receiving the request for registration and the user identification. The central node sends the first set of random number and the second set of random number to the first sensor node and the second sensor node respectively.

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; a second sensor node; and a 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 the second sensor node respectively, wherein a password and a message are encoded and decoded by using a Padgen function operation with the first set of random number and the second set of random number for generating a cover-coded password and a first cover-coded message transmitted between the first sensor node and the central node, or generating the cover-coded password a second cover-coded message transmitted between the second sensor node and the central node.
