A deterministic chaotic random number generation system, and a data encryption method and apparatus using the same

摘要

The present invention relates to a deterministic chaotic random number generation system and a method and apparatus for encrypting data using the same. The conventional methods are basically not security but computationally secure And it is very complicated and it is difficult to realize a high speed in terms of the speed of the encryption method. In order to overcome such disadvantages, the present invention recursively calculates a random number of chaos generated by initializing a random number and a random number, determines a run-time encryption key by key mapping from a state function generated for each recursive calculation, The present invention can determine the initial condition and the system configuration condition of the random number generator and decrypt the data only by knowing the correct password in order to decrypt the encrypted data, The present invention can be implemented at a high speed since the system is simple in structure and the amount of calculation is small by adding or subtracting a random number generated from a random number generator to a message.
