In the encryption/decryption method, a random number sequence {r i} is generated on the basis of a given key system K and encryption is performed by an exclusive OR of the random number sequence {r i} with a plain text. Further, the key system K is automatically sequentially rewritten into a series of new key systems each tame when the number "c" of use times of the key system reaches a predetermined number "n" and encryption of plain texts thereafter is continued while generating random numbers using the series of the rewritten key systems. Likewise, in decryption as well, since decryption is performed using a key system automatically rewritten each time when the number "c" of use times reaches a predetermined number "n", a third party cannot reproduce the key system and therefore cannot decipher a cipher text.
