Dynamic Stream Ciphering Algorithm

TL;DR: A new technique base on dynamic stream cipher algorithm to generate stream cipher key base on the use set of LFSR with fix arrangement is implemented and Basic Efficient Criteria on Key Generator (KG) is implemented to test the result which is store in binary files.

Abstract: The main idea of any stream cipher algorithm is to generate stream cipher key base on the use set of LFSR with fix arrangement, all this LFSR are filling depending on the value of the basic key. In this paper we implement new technique base on dynamic stream cipher algorithm. In this algorithm we implemented dynamic stream cipher algorithm which base on idea of changing the structure of the LFSR with each change in BK and MK to get complex ciphering algorithm this is done by use a bank of LFSR store in file and we select random 10 register that is used in algorithm to generate the key. We implement Basic Efficient Criteria on Key Generator (KG) to test the result which is store in binary files. Three sample of key generation (KG) store in the binary file are test and all the sample is pass the test.
