These days, with the emergence of the concept of ubiquitous computing, sensor networks that collect, analyze and process all the information through the sensors have become of huge interest. However, sensor network technology fundamentally has wireless communication infrastructure as its foundation and thus has security weakness and limitations such as low(More)
There is encryption algorithms used in GSM. This is for to encrypt the information when transmit from mobile station to base station during communication. As stated that A5/1 is strong algorithm but it cryptanalysis by cryptanalysts. This paper modified concept to improve A5/1 encryption algorithm by consideration of feedback combining function of LFSRs(More)
