of the most effective and conventional ways to protect multimedia information. One the widely known models for image encryption is Cellular Automata (CA). CA is a self-organized structure with a set of cells in which each cell is updated by certain rules that are dependent on a limited number of neighboring cells. The major disadvantages of cellular automata in cryptography include limited number of reversal rules and inability to produce long sequences of states

Contents We have seen an example of use of finite automata in describing the operation of a simplified version of vending machine. Many other systems operating in practice can also be modeled by finite automata such as control circuits of computers‚ computer network communication protocols‚ lexical analysers for compilers etc. Many of those systems fall into the class of systems called reactive system. A reactive system is a system that changes its actions‚ outputs and conditions/status in response

Languages‚ Grammars‚ and Automata Theory Discrete Mathematics Linda Chalk Colorado Technical University Professor Timothy Manzke December 17‚ 2010 Languages‚ grammars and automata theory are all related to computer applications. Grammar is the rule for language structure regardless of the meaning. For computer programming languages context free grammar (CFG) is commonly used. Formal language as opposed to natural language must be used with computer applications because natural language

Lecture Two Lexical Analysis 1 What is Lexical Analysis? Lexical Analyzer reads the source program character by character to produce tokens. Normally a lexical analyzer doesn’t return a list of tokens at one shot‚ it returns a token when the parser asks a token from it. source program lexical analyzer token parser get next token symbol table 2 The lexical analyzer deals with small-scale language constructs‚ such as names and numeric literals. The syntax analyzer deals
