Abstract: PROBLEM TO BE SOLVED: To provide a shared key exchanging system with which a shared key can be exchanged safely without requiring previous cryptographic key generation/exchange for certification between respective pieces of communication equipment. SOLUTION: Two pieces of communication equipment for performing cryptographic communication encipher a disclosed numerical value generated by their own disclosed numerical coefficient means 22 through an enciphering means 23 while using the disclosed key of a managing center and transmit it to the managing center. The managing center deciphers this numerical value while using its own secret key and after two disclosed numerical values of two pieces of communication equipment are provided, the deciphered disclosed numerical value and a prescribed function enciphered while using its own secret key are transmitted to two pieces of communication equipment for performing cryptographic communication.  Every communication equipment performs certification by deciphering the received value through a deciphering means 24 while using the disclosed key of the managing center, provides a deciphered value, calculates a function (g) from that deciphered value and its own disclosed numerical value and further calculates the shared key through a shared key calculating means 26 while using a random number.

Abstract: PURPOSE:To reduce the load on an interruption routine and improve the detection precision by deciding whether or not each data stored in a specific storage area is unprocessed new data and processing only the new data. CONSTITUTION:The interruption routine reads in the detection data GYRTD of a gyro sensor 10, converted by an A/D converting circuit 10 into a 10-bit digital signal, at specific intervals of time and stores those detection data GYRTD in a storage area wherein a 16-bit signal can be stored.
