dc.description.abstractOrdinary techniques of text compression provide some degree of privacy for messages being stored or transmitted. First, by recoding messages compression protects them from the casual observer. Second, by removing redundancy it denies a cryptanalyst the leverage of the normal statistical regularities in natural language. Third and most important, the best text compression systems use adaptive modeling so that they can take advantage of the characteristics of the text being transmitted. The model acts as a very large key, without which decryption is impossible. Adaptive modeling means that the key depends on the entire text which has been transmitted so far since the time the encoder/decoder system was initialized. This paper introduces the modern approach to text compression and describes a highly effective adaptive method, with particular emphasis on its potential for protecting messages from eavesdroppers. The technique is potentially fast and provides both encryption and data compression.eng
