    摘要: A random number generator comprising a plurality of pseudo random number generating units that can respectively output random numbers in specified pseudo random number systems, an output random number generating unit that generates output random numbers based on outputs from a plurality of pseudo random number generating units, a physical random number generator that generates physical random numbers, and a switching unit for switching between the necessity and the non-necessity of updating output values from pseudo random number generating units based on physical random numbers generated by the physical random number generator. Based on which pseudo random number system an output random number is generated is randomly switched based on a physical random number, making it very difficult to predict a random number compared with a conventional one.

    摘要: A random number generation device comprises a pseudo random number generation section that is capable of outputting random numbers of a plurality of different pseudo random number sequences, a physical random number generation section for generating physical random numbers, and a switching section for switching the pseudo random number sequence of random numbers output by the pseudo random number generation section on the basis of the physical random numbers generated by the physical random number generation section, where the output of the pseudo random number generation section is used as output random numbers. Since the plurality of different pseudo random number sequences are switched and output according to the physical random numbers, predictability of the random numbers can be reduced in comparison to a conventional random number generation device that uses only pseudo random numbers. Furthermore, since the physical random numbers are not directly used as the output random numbers, any adverse effect on the predictability of the output random numbers is substantially reduced compared with a conventional device even if the physical random number generating means are somehow manipulated from the outside.

    摘要: A keyless entry system comprising a transmitter and a receiver. The transmitter increases a first number stored in the volatile memory according to rules, and transmits the first number by radio. The receiver receives the first number, and if the first number is greater than a second number stored in a memory, outputs a signal to indicate being authenticated as correct and updates the second number to the first number. Further, each time increase in the first number becomes a multiple of a predetermined number, the transmitter writes into a non-volatile memory a third number equal to the predetermined number plus the first number. When the first number in the volatile memory is erased due to the exchange, etc., of the battery, the transmitter reads out the third number from the non-volatile memory and writes the third number as the first number into the volatile memory.

    摘要: When transmitting encoded video data and audio data, a transmitter 201 also transmits a decoding method 107 generated by decoding-method generation means 203. In the case of a receiver 202, decoding control means 111 controls decoding means 208 in accordance with a received decoding method 113 and thereby, decodes video data and audio data 115. Thus, it is unnecessary for the receiver 202 to previously prepare all of a plurality of decoding methods and the transmitter 201 does not need to encode video data or audio data in accordance with the decoding method owned by the receiver 202.
