Will the Butterfly Cipher keep your Network Data secure? Developments in Computer Encryption

Introduction Encryption has been used as a method of protecting computer privacy since 1977. Secret communication plays an increasing role in organizations especially banking, industry, commerce, telecommunication etc. The basic idea of encryption is to modify the network traffic in such a way that its content can be reconstructed only by a legal recipient.
