Combined Multi-encryption Techniques for Text Securing Using Block Cipher and Stream Cipher Crypto-systems

Abstract

Due to the growth of electronic intrusion techniques and personal data control, it is necessary for private or public organization to secures their data and prove their owner rights. Encryption techniques provide a useful mean to secure internet files exchange or numeric storage data. Old techniques present some disadvantages decreasing their robustness face to attacks. In this paper a new approach presenting a multi-encryption system for text and file text is presented. Dividing the file in different parts, each part is encrypted by a different algorithm to generate a poly-encrypted file.
