Abstract
Now-a-days we are enveloped by technologies and data is an essential part of any technology. It is obvious that communication between different clients is an important aspect of any system. Thus data are sent in between different clients to accomplish communication. After a plaintext is encrypted and cipher text is found, the cipher text is made to transmit over an unsecure channel. Encryption techniques are basically divided into two types: Symmetric key encryption and Asymmetric Key encryption. Symmetric key encryption is usually preferred over asymmetric key due to its fastness, low complexity, lesser computational burden and use of one key for both encryption and decryption process. Previously different encryption algorithms were developed i.e. DES, 3DES, AES and RC2 as symmetric key and Diffie-Hellman and RSA as asymmetric key algorithms. In this paper we have developed an encryption algorithm “Dual CBC Encryption Algorithm (DCEA)” which uses a twice implementation of Cipher Block Chaining (CBC) once in practical order and other in reverse order of the outputted cipher text. The use of XOR operation eases the hardware implementation, consumption of lesser computational power, smaller complexity and easy encryption and decryption processes. The key used here could be of any length but it is preferred to select a key between 4 Bytes and 16 Bytes. On comparison of Avalanche Effect with the other basis Algorithms like Blowfish, 3DES, DES, RC2 and AES algorithm DCEA has a much better value. Moreover DCEA is trustworthy to several attacks like frequency analysis attack, cipher text only attacks, known plaintext attack and chosen plaintext attack. In addition to that the algorithm has better encryption time in comparison to DCA encryption algorithm. The experimental and analytical results described in further sections of this paper give stronger proof to DCEA’s strength.
