Title: On-vehicle receiver and wireless system for vehicle
Inventor: KANDA KOJI
IPC: H04W4/04
Filed: 2001-10-01
Abstract: PROBLEM TO BE SOLVED: To reduce a processing load attended with deciphering of enciphered data in an on-vehicle receiver for receiving/deciphering the enciphered data for using them for controlling on-vehicle equipment. SOLUTION: Inside a RAM, a buffer area is secured for storing enciphered data and deciphered data thereof as a set. When the enciphered data are received, it is decided whether the received enciphered data are stored on the buffer or not and when such data are not stored (S120: NO), these data are deciphered. Then, these deciphered data are validated (S130) and these deciphered data are stored on the buffer together with the enciphered data (S150). When the received enciphered data are stored on the buffer (S120: YES), on the other hand, in place of deciphering of these enciphered data, the deciphered data stored in the buffer are validated (S160). Namely, as long as received enciphered data are matched with the enciphered data stored on the buffer, deciphering is not performed, so that the processing burden of a CPU for performing deciphering can be reduced.
