A Proposed Design of an Encryption Algorith Applied to Secure File Transfer over Computer Network

Abstract

Cryptography is ihe science and art of keeping data and messages Secure Encryption is the major component of any solution adopted to achieve security over communication and computer networks, since it guards against active and passive wiretapping. Also it can he used for digital signature to authenticate messages, files and data. In addition it is1 the only method of protecting stored information once the physical security is broken or logon authentication mechanisms are bypassed
