Abstract
The utility model relates to a random number sequence based on a fractional-order automatic-switchover chaotic system. The random number sequence comprises a fractional-order automatic-switchover chaotic system (1), an x-path random signal (2), a y-path random signal (3), a z-path random signal (4), voltage comparators (5), (6) and (7), an x-path random sequence (8), a y-path random sequence (9), and a z-path random sequence (10). The x-path random signal (2), the y-path random signal (3), and the z-path random signal (4) are generated by the fractional-order automatic-switchover chaotic system (1); and the x-path random sequence (8), the y-path random sequence (9) and the z-path random sequence (10) are generated by the x-path random signal (2), the y-path random signal (3) and the z-path random signal (4) through the three voltage comparators (5), (6) and (7). The random number sequence based on the fractional-order automatic-switchover chaotic system can be used for improving the security performance of communication systems in digital communication based on the fractional-order chaos.
Description
Technical field
The utility model relates to a kind of Serial No., particularly a kind of random digit sequence of fractional order automatically switched chaotic system.
Background technology
Along with the development of private communication technology, how to obtain randomness than higher Serial No., become major issue in the secure communication; Existing digital communication sequence; Like m sequence etc.,, and decoded by the interceptor easily because randomness is lower; Thereby cause the dangerous of communication, this is the weak point of prior art.
Summary of the invention
The utility model proposes the random digit sequence based on the fractional order automatically switched chaotic system, can effectively improve the performance at random of Serial No., thereby improves the difficulty that the interceptor decodes.
The technical scheme that the utility model adopts is: based on the random digit sequence of fractional order automatically switched chaotic system, be made up of fractional order automatically switched chaotic system (1), x road random signal (2), y road random signal (3), z road random signal (4), voltage comparator (5), voltage comparator (6), voltage comparator (7) and x road random sequence (8), y road random sequence (9), z road random sequence (10); The x, y, z three tunnel random signals (2), (3), (4) that are produced by fractional order automatically switched chaotic system (1) produce three tunnel random sequences (8), (9), (10) through three voltage comparators (5), (6), (7).
The beneficial effect of the utility model is: the security performance that is used for can improving based on the digital communication of chaos communication system.
Description of drawings
