INFINITE ENCRYPTION/DECRYPTION DEVICE USING INFINITE RANDOM NUMBER GENERATION DEVICE AND INFINITE ENCRYPTION DEVICE

摘要

PROBLEM TO BE SOLVED: To generate an efficient pseudo-random number which can be used in a small-scale computer system and a mobile terminal since the necessity of sophisticated encryption and decryption which can easily be used for a memory disk is increasing, and to perform robust encryption and decryption for a memory disk by making a pseudo-random number generation device have n encryption keys and use a combination of the encryption keys so as to extract the maximum performance of the pseudo-random number.;SOLUTION: Since a random number sequence generated by a reproducible pseudo-random number has an N-1 cycle, a mechanism has been developed for using the generated random number sequence in this cycle without entering the next cycle. Moreover, the random number generation device includes a mechanism for extracting a random number sequence without overlap in the random number sequence N-1 generated by the pseudo-random number so as to maximize the disorder of the random number and extract the maximum performance of the random number generation device.;COPYRIGHT: (C)2010,JPO&INPIT
