Linear feedback shift register; Stream ciphers.Abstract
This paper proposes a method of the stream ciphers attack in which its keystream is generated by the linear feedback shift register based on a pair of known plaintext, ciphertext. Based on these studies, the authors will develop the stream cipher attacking theory with its key sequence generated by the multi-layer shift register in the next research. The research results can be applied to build stream ciphers that overcome the disadvantages that we have proposed in this paper in order to improve the safety and security of the current communication systems.
