摘要： PROBLEM TO BE SOLVED: To provide a data conversion apparatus and method capable of reducing the amount of information required for data converting using an AES cryptography, and to provide a communication system. SOLUTION: In the apparatus, 8-bit partial data a i, j-ci of conversion object data being in the same column by applying ShiftRows are converted into 32-bit intermediate data h (j) i by using a lookup table T i corresponding to the partial data and expressed by any two of the three SubBytes conversions s(x), 2s(x), 3s(x). By taking the exclusive OR of the intermediate data h (j) i bit by bit, after-conversion data d j obtained by applying each conversion-SubBytes, ShiftRows, and MixColumns in the AES cryptography- to the conversion object data a i, j are found collectively.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle theft tracing system, a vehicle theft monitoring device, and a vehicle theft tracing method capable of securing a high security against vehicle theft. SOLUTION: Each vehicle 2 is furnished with an alarm function device 5 and a radio communication device 10. The alarm function device 5 judges whether a deed for vehicle theft is being conducted on the basis of the sensing signals given by a group 8 of sensors, and if yes in judgement, the device 5 emits an alarm through a horn 9 and transmits a theft notification signal Sa. The radio communication 10 can exchange radio LAN communications with the alarm function device 5, and when receiving the theft notification signal Sa from the device 5, transmits a theft notification signal Sb in response to Sa. Even if the burglar has removed the alarm function device 5, the radio communication device 10 left in the vehicle 2 puts the vehicle 2 in the condition that the signal Sb is transmitted from the vehicle 2.

摘要： PROBLEM TO BE SOLVED: To provide a side channel evaluation device and a side channel evaluation method which can shorten the time of resistance evaluation for unauthorized decryption of an encryption device.SOLUTION: In the selection function database 9 of a side channel evaluation device 1, a plurality of selection functions used for calculation of fragility evaluation are registered. The selection function in the selection function database 9 is a selection function with a partial key k less than 16 bites, out of all selection functions AES-128 that must be confirmed under conditions that the implementation information is unavailable. A selection function with a partial key k of less than 16 bites becomes a use function because a selection function with a partial key k of more than 16 bites has high resistance against attack, because full number search of encryption key is an efficient attack method, and evaluation by a selection function with less than 16 bites is adequate or enough.
