Secure True Random Number Generator in Wireless Network

During last decade, Wireless LAN (WLAN) has been very important and developed area of technology and science. Nowadays a level of security that can exceed the security of a WLAN is provided by using security protocols. Not only the security of WLAN can increase by cryptography algorithms their own, but also will be more powerful if True Random Numbers are being used in Cryptography algorithms. Today it is hardly possible to disregard the vital role of random numbers in Cryptography consequently security of wireless Networks in case of key exchange algorithms or nonce to convince the other part is trusted. The aim of thesis is generating secure true random numbers in context of Ad hoc WLAN. To this aim, Diffusion RNGLigth technique, which is modification of Scatter RNGLigth technique that produced true random numbers using sensory reading on Wireless Sensor Network (WSN) [1], is implemented. These modifications consist of adding and changing some parts of the secure frameworks and using AES and Triple-DES instead of DES in encryption/decryption and CMAC. In addition, produced random numbers using Diffusion RNGLigth are evaluated by NIST statistical test. The results show that p-values of Diffusion RNGLigth using AES 60% have improved in comparison with Diffusion RNGLigth using Triple-DES, also p-values of Diffusion RNGLigth using Triple-DES 60% have improved in comparison with Scatter RNGLigth.
