Cryptanalysis of the Bluetooth Security Protocol Using Enhanced DNA Sticker Model

E0 is a robust stream cipher algorithm that is commonly used in Bluetooth security protocols. The algorithm works by using linear feedback shift registers to generate a stream of keys. These keys are then used to encrypt data. We can consider the method used to generate these keys to be based on propositional logic. The inputs for this logic are the outputs of the linear feedback shift registers, and the output is the binary sequence of the final key string. To construct a tube that collects the correct memory complexes, each step depends on a satisfying bit determined within the folds of the final key sequence, Zi. We have enhanced the sticker model to make it more effective in E0 cryptanalysis. This includes converting sequential search for all initial values of the shift registers into parallel search and changing the dependence of the decision on the logical variables of the regions individually. To launch an attack on E0 Algorithm, you would need to perform 237operations and know at most 200 key stream bits from the first frame of the output cipher text. Compared to earlier attacking algorithms, this is the best result achieved so far.
