SEQUENTIAL ENCRYPTION METHOD BASED ON MULTIPLE KEY STREAM PASSWORDS

摘要

Disclosed is a sequential encryption method based on multiple key stream passwords, comprising the following steps: acquiring plain text data, and storing the acquired plain text data in the form of a circular chain table; respectively storing a plurality of key sequences in the form of a circular chain table; performing a bit operation between the various key sequences respectively according to a specified starting bit, so as to generate a stream random sequence; and according to the stream random sequence, reconstructing the plain text data to generate encrypted cipher text data. The method involves simple encoding and decoding, and decipherment is very difficu the method is easy to realize by means of a computer, without the need for an auxiliary hardware device, and has a fast encoding and decoding speed; and the generated cipher text has excellent properties such as a strong diffusion property, and good anti-intercepting performance.
