阐述了无线局域网中的有线等效加密(WEP,Wired Equivalent Privacy)和无线局域网安全存取(WPA,Wi-Fi Protected Access)两种主要的安全加密协议,研究了其加密算法的加密原理和加密流程,指出了加密机制的理论缺陷,并通过注入式抓包破解WEP加密仿真实验和字典暴力,破解WPA密匙仿真实验验证并对比了WEP和WPA加密算法的缺陷,仿真证明了WEP加密是不安全的加密方式,不再符合当前无线局域网的安全要求,因为WPA加密机制破解难度较大所以符合安全要求,但仍具风险并需要改进,最后提出了针对协议安全性的改进。
This paper describes two main security encryption protocols, WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access), studies the encryption principle and encryption Flow, pointed out the theoretical flaws of the encryption mechanism, and cracked the WEP encryption simulation experiment and the dictionary violence by injecting the capture packet, cracked the WPA key simulation experiment and verified the defects of the WEP and WPA encryption algorithms. The simulation proves that the WEP encryption is not The secure encryption method no longer meets the current WLAN security requirements. Because the WPA encryption mechanism is more difficult to crack, it meets the security requirements but is still in risk and needs improvement. Finally, the protocol security improvements are proposed.
