Encryption is of prime importance when confidential data is transmitted over the network. Varied encryption algorithms like AES, DES, RC4 and others are available for the same. The most widely accepted algorithm is AES algorithm. The authors have proposed a new algorithm based on the concept used by Rijmen and Daemen (Rijndael algorithm), the founders of AES algorithm. The proposed algorithm encrypts and decrypts two 128 bits data simultaneously i.e. 256 bits data, thus providing strong encryption accompanied with complex processing. The proposed Feistal algorithm uses various invertible, self-invertible, and non-invertible components of modern encryption ciphers and key generation same as that of AES.
