The application research of TNC hyperchaos encryption in WLAN security

Against the existing security issues in WLAN, a modified hyper-chaotic sequence encryption algorithm for the security of WLAN was given.It proved to be effective to resistance the attack of exhaustive method; sub-Nyquist sampling interval was used to increase the key space and had proved that made the arithmetic has anti nonlinear reorganization attack capability; realized the algorithmpsilas encryption and decryption in the WLAN by the use of Matlab simulation platform got some satisfactory results and a testament to the arithmetic which is faster and easier implementation by software, had advantages of a large key space and so on.
