As the transmission of data over internet is increasing; the protection issues of data are increasing as well. In order to protect the data and to secure it against intruders, there is a need of such systems which provide security to data. These techniques are known as cryptography or simply cipher. One of the ciphers is International Data Encryption Algorithm (IDEA). This cipher is symmetric in nature i.e. uses only one key both for encryption and decryption. IDEA uses 128-bit key to encrypt the 64-bit data using certain rounds of operation. In this case, eight and half rounds are used.
