In order to ensure the security of the wireless network, Wi -Fi Alliance uses stream cipher algorithm RC4 to encrypt data in the security protocol WEP/WPA. RC4 is a fast algorithm but easy to break. To solve the problem, WPA2 is proposed which uses block cipher algorithm to improve the anti-crack ability of wireless system. AES is time consuming because of its complexity even though it is characterized by high security. To respect the safe and real-time requirements at the same time, we propose

... a new chaotic encryption algorithm CPRS based on Tent chaotic maps. Chaos is pseudo-random and sensitive to initial parameters which improves the safety of algorithm. Besides, Tent chaotic maps used in the crypto-system is a linear equation which reduces the time of encryption. Then, to quantify the rapidity and security level of the CPRS algorithm, we compare it with the AES algorithm.
