Implementation of Public Key Cryptographic System: RSA
In many business sectors secure and efficient data transfer is essential. To ensure the security to the applications of business, the business sectors use Public Key Cryptographic Systems (PKCS). An RSA system generally belongs to the category of PKCS. RSA encryption is one of the public-key methods that have been popular in last decade. In particular, the RSA algorithm is used in many applications. Although the security of RSA is beyond doubt, the evolution in computing power has caused a growth in the necessary key length. The performance characteristics of RSA are observed by implementing the algorithms for computation.
