    • In the encryption/decryption method, a random number sequence {ri} is generated on the basis of a given multiple-affine key system K and encryption is performed by an exclusive OR of the random number sequence {ri} with a plain text. Further, the multiple-affine key system K is automatically sequentially rewritten into a series of new multiple-affine key systems each time when the number of use times of the multiple-affine key system reaches a predetermined number and encryption of plain texts thereafter is continued while generating random numbers using the series of the rewritten multiple-affine key systems. Likewise, in decryption as well, since decryption is performed using a multiple-affine key system automatically rewritten each time when the number of use times reaches a predetermined number, a third party cannot reproduce the multiple-affine key system and therefore cannot decipher a cipher text.
    • 在加密/解密方法中,基于给定的多遍密钥系统K生成随机数序列,并且通过随机数序列{ r }使用纯文本。 此外,多次仿射键系统K自动顺序地重写成一系列新的多重仿射键系统,每当多遍仿射键系统的使用次数达到预定数量时,其后的纯文本的加密继续 同时使用一系列重写的多重仿射键系统产生随机数。 同样地,在解密中也是如此,由于使用多次仿射密钥系统进行解密,所以在每次使用次数达到规定数量的情况下,自动重写的多重仿射密钥系统,第三方不能再现多重仿射密钥系统,因此不能解密密码 文本。
