The e-data usage is increasing day-by-day. Now-a-days, exchange of data over the internet is increased higher than before. Security is the main issue in communication over a network. Protection must be given against attackers. Solutions for network security comes with concepts like cryptography in which distribution of keys have been done. Cryptography plays a vital role in providing security. There are two types of cryptography mechanism: symmetric and asymmetric key. Symmetric key use single key for encryption and decryption whereas asymmetric key uses two keys one for encryption another for decryption.
