【摘要】：當前針對無線局域網進行的非法接入攻擊與竊聽攻擊十分嚴重,造成了非常嚴重的安全問題。為了解決目前無線局域網容易遭受攻擊者發(fā)起的非法接入攻擊和竊聽攻擊的問題,本文使用了近場通信技術對無線局域網的安全弱點進行加強,并采用了著色Petri網對無線局域網與近場通信進行了建模。通過解決在模型中暴露的問題,本文設計出了“通過NFC認證的WLAN接入協(xié)議”,并針對該協(xié)議的非法接入攻擊與竊聽攻擊進行了著色Petri網建模�！巴ㄟ^NFC認證的WLAN接入協(xié)議”采用Diffie-Hellman密鑰交換算法與第二代安全散列算法生成基于近場通信協(xié)議棧的安全隧道。防范非法接入方面采用公開密碼體制下的橢圓曲線數(shù)字簽名算法對接入者身份進行認證。防范竊聽方面采用隨機生成的預共享密鑰來配置無線局域網接入點保證用戶接入的一次一密性。著色Petri網模型的仿真驗證表明,通過NFC認證的WLAN接入協(xié)議對于無線局域網的非法接入攻擊與竊聽攻擊有著良好的抵抗效果。并且協(xié)議本身也可以抵抗針對近場通信的竊聽攻擊、數(shù)據篡改攻擊、重放攻擊和中間人攻擊。本文針對設計出的協(xié)議進行了協(xié)議需求分析與架構設計,并給出了一個計算機上的原型實現(xiàn)。原型實現(xiàn)的運行效果表明通過NFC認證的WLAN接入協(xié)議能夠足夠穩(wěn)健的運行并有著良好的應用前景,可以解決當前針對無線局域網的非法接入攻擊與竊聽攻擊。
[Abstract]:At present, the illegal access attack and eavesdropping attack against WLAN are very serious, which has caused very serious security problems. In order to solve the problem that WLAN is vulnerable to illegal access attack and eavesdropping attack launched by attacker, In this paper, we use near field communication technology to strengthen the security weakness of WLAN, and use colored Petri net to model WLAN and near field communication. In this paper, "WLAN access protocol authenticated by NFC" is designed, and the model of colored Petri net for illegal access attack and eavesdropping attack of this protocol is presented. Diffie-Hellman key exchange algorithm and Diffie-Hellman key exchange algorithm are used in WLAN access Protocol authenticated by NFC. The second generation secure hash algorithm is used to generate secure tunnel based on near field communication protocol stack. In the aspect of preventing illegal access, the elliptic curve digital signature algorithm based on public cryptosystem is used to authenticate the identity of the accessor and to guard against eavesdropping. A random preshared key is used to configure the WLAN access point to ensure the one-time density of the user access. The simulation results of the colored Petri net model show that, The WLAN access protocol authenticated by NFC has good resistance to illegal access attack and eavesdropping attack of WLAN, and the protocol itself can resist eavesdropping attack and data tampering attack against near field communication. Replay attack and man-in-the-middle attack. A prototype implementation on a computer is given. The result of the prototype implementation shows that the WLAN access protocol authenticated by NFC can run stably enough and has a good application prospect. It can solve the current illegal access attacks and eavesdropping attacks against WLAN.
