A new class of models, formalisms and mechanisms has recently evolved for describing concurrent and distributed computations based on the concept of “coordination”. The purpos...
Abstract: Since von Neumann's seminal work around 1950, computer scientists and others have studied the algorithms needed to support self-replicating systems. Much of this wor...
Natural language processing has been in existence for more than fifty years. During this time, it has significantly contributed to the field of human-computer interaction in terms...
This paper describes the state of the art for cryptographic hash functions. Different definitions are compared, and the few theoretical results on hash functions are discussed. A...
This paper considers modern secret-key block ciphers. The theory behind the design and analysis of modern block ciphers is explained, and the most important known attacks are outli...
Abstract. In 1982, Bennett and Brassard suggested a new way to provide privacy in long distance communications with security based on the correctness of the basic principles of qua...
