As the use of internet is becoming widely accepted these days, it is a trend of transmitting data over the network. International Data Encryption Algorithm (IDEA) is a symmetric key encryption technique and uses 128-bit key over 64-bit plain text with eight and a half round. To enhance the technology in IDEA, a new approach is introduced in which the authors will establish two different keys for encryption and decryption respectively which was single key in IDEA. This will introduce more security in IDEA by making it an asymmetric key encryption algorithm.
