Abstract

The Whole point of cryptography is to solve problems. It solves problems that involve secrecy, authentication ,integrity and dishonest people .A protocol Is a series of steps ,involving two or more parties designed to accomplish a task. A series of steps means that the protocol has a sequence, from start to finish. Analyzing stream ciphers is often easier than analyzing block ciphers. For example, one important metric used to analyze LFSR-based generators is linear complexity, or linear span. This is defined as the length, n, of the shortest LFSR that can mimic the generator output. Any sequence generated by a finite-state machine over a finite field has a finite linear complexity [1006]. Linear complexity is important because a simple algorithm, called the Berlekamp-Massey algorithm, can generate this LFSR after examining only 2n bits of the keystream [1005]. Once you’ve generated this LFSR, you’ve broken the stream cipher.
