Abstract: Random number generating, encrypting, and decrypting apparatus, method thereof, program thereof, and recording medium thereof are provided. Random numbers for cryptographic applications are generated by a CA core. The CA core is composed of one-dimensional, two-state, and three-neighbor cell automaton. A total of three inputs for the own cell and both neighbor cells are input to each cell. Each cell performs a logical operation and outputs the result of the logical operation. Each cell contains a register. Each register captures the result of the logical operation in synchronization with a clock and stores the result. An output of a cell is fed back to the cell to perform an arithmetic calculation at the next time step. In this case, a rotation shift operation of which outputs of cells are shifted to the left and fed back to the cells is performed. To output random numbers having many bits, 40 bits of outputs of cells are selected.

Abstract: A part of data is extracted as an IV from cipher text at the previous time. An EX-OR gate ORes the IV and a common key and outputs a cipher key. Data to be transmitted are encrypted with the cipher key according to stream cipher. When ciphered data 15a are obtained at time tn?1, an IV extracted from the ciphered data 15a is supplied to an EX-OR gate 11b. The EX-OR gate 11b exclusively ORes the IV and a common key 12b and outputs a cipher key 13b. Since the cipher key 13b and transmission data are exclusively ORed, encryption is performed according to the stream cipher. As a result, ciphered data 15b at time tn is obtained. Next, with the IV extracted from the ciphered data 15b, encryption at time tn+1 is performed. Thereafter, at each time, a part of cipher text is used as an IV. The encrypting process is repeated.
