Secure communication of static information by electronic means
Abstract
A method and apparatus (10) for the secure transmission of static data (16) from a tag (11) to a remote reader (12). Each time the static data (16) is to be transmitted to the reader (12), the 10 bits of static data (16) are combined with 54 bits of binary data (21), which constantly change from one transmission to the next, into a 64-bit number (22). This number is then encrypted and transmitted to the remote reader (12) where it is decrypted (26) to produce the same 64 bit number that was encrypted in the tag (11). With a continual change in the value of the 64 bit number (22) in the tag, the encrypted numbers transmitted to the reader (12) will appear to be dynamic in character rather than being static.
