A novel package of key generation and integrity validation in symmetric key cryptography

In this paper we presents a new cryptography method on  symmetric key Cryptography along with that it will ensure the integrity of the data during the transmission. Here encryption and decryption operation is performed on   bit stream of data. It is suitable for any type of text files. This method of encryption is simple and powerful to secure data in network against passive attack like traffic analysis to provide data confidentiality. The Cryptography package deals with generating a simple encryption key by choosing a byte of data in the plaintext. By using that secure encryption key Plain text is converted to cipher text and in the destination Cipher text is converted to plain text by performing basic XOR and other operation. To ensure integrity of data available parity bit methods are applied.
