Wireless Data Communication: Security-Throughput Tradeoff

Modern wireless networks enable network operators to offer users a wider range of more advanced services by using high data transmission capabilities. Transmission over wireless networks are susceptible to both passive and active attacks by intruders since many applications do not encrypt the data they communicate over the network due to the fact that, encryption of data results in throughput loss, hence limited access to services by users.There is need to develop highly secured wireless communication systems without compromising the unlimited access to services by users. Hence any valuable research effort on wireless security should address the tradeoff between security and throughput.The new scheme presented in this book draws its motivation from the setbacks of existing wireless security schemes such as key management for large networks and processing time. The scheme is implemented using FPGA-based signal processing techniques in conjunction with RSA cryptography. It uses shorter keys but has security level higher than that of the traditional 1024-bit RSA. This work could serve as a platform for wireless communication system designers to develop modern high performance systems.
