Abstract
The Four Stage Encryption System introduced by Acharyulu and Appaji provides secrecy even when the attacker has some samples of plain texts and their corresponding cipher texts obtained with the same key, because the cipher text generated each time, for the same plain text with the same key, is different. In other words, the system is secure against adaptive chosen-plain text attack. Another interesting feature is that even the size of the cipher text, for given plain text under a given key, is unpredictable. In this paper the four stage encryption system is generalized as Generated Partitioned Output Crypto System and some variations that can be taken up are suggested. A pure mathematical system called Partitioned Output Crypto System is introduced as a further step of generalization in order to study the properties of the system. A correlation with the existing systems is taken up as a part of the study of the properties. It's observed that the system shares the properties of multifunction.
