A Secure Private Key Encryption Technique For Data Security in Modern Cryptosystem

The present paper provides a conceptual framework on the proposed private key encryption technique that can be used for data security in modern cryptosystem. This encryption technique uses the concept of arithmetic coding and can be used as an independent system as well as can be clubbed with any of the encryption system that works on floating point numbers. It provides you with a 256 character key (length of the key can be increased or decreased on the basic of the character set required) that can be used as a one time resident key or a key for every message depending on the level of security required. The proposed technique converts a word of text into a floating-point number that lie in between 0 and 1. This floating point no. is obtained on the basis of the probability of characters contained within the word of text and the one time key which has been provided .The security level can be further increased by generating different floating point number every time when a word repeat and increasing the length of the key.
