USE OF 32-BIT RANDOM NUMBERS TO PRODUCE CIPHER KEY STREAM FOR 8-BIT DATA STREAM

摘要

A method of enciphering information comprises generating five index values by performing modulo division on a 32-bit binary input value, identifying five 8-bit output patterns based on the five index values, and enciphering or deciphering five bytes of text using the five 8-bit output patterns.

1. A method, comprising:
transforming a 32-bit random number into a plurality of indices; identifying a plurality of 8-bit binary cipher keys each comprising four ones and four zeros, based on the plurality of indices; and enciphering multiple 8-bit units of cleartext or deciphering multiple 8-bit units of ciphertext by modifying each unit according to a corresponding one of the cipher keys.
