  • Secret key programming technique for transponders using encryption
    Patent number: 7327216
    Abstract: A secret key is programmed into a key transponder from a base station wherein the key transponder stores a fixed ID, a first default key segment stored in a first memory page, and a second default key segment stored in a second memory page. The secret key comprises a first new secret key segment to be stored in the first memory page of the key transponder and a second new secret key segment to be stored in the second memory page of the key transponder. A mutual authentication process is initially conducted using the default key. Write commands are sent to the key transponder in transferring each key segment. Write acknowledgement signals and confirmatory reading back of the data are employed for ensuring proper storage of the secret key. Recovery from the most probable types of errors enables successful programming of key transponders in an efficient manner with a low loss rate.

  • System and method for tire pressure monitoring
    Publication number: 20080018448
    Abstract: A system for monitoring at least one parameter of vehicle tire includes a receiver and a transmitter. The transmitter corresponds to the tire and has a programmable memory storing a code and one of a set of locally unique identifiers. The transmitter generates an encrypted portion of a transmitted signal based on the locally unique identifier and the code. The transmitter generates a data portion of the transmitted signal based on sensing at least one parameter of the tire. The receiver stores a set of locally unique identifiers and the code. The receiver receives the transmitted signal. The encrypted portion is decrypted using at least one of the code and the locally unique identifiers to produce a decrypted portion. A check is made to determine if the decrypted portion matches one of the code and the locally unique identifiers and, if so, the data portion is processed.
