Selective encryption is a technique which uses subset of bit stream rather than entire bit stream. It provides a number of advantages in secured communication process. In the selective encryption, only a random (r) of whole message/plain text is encrypted. It increases speed of encryption/decryption in case of any cryptography algorithm.

Its advantages are:

It reduces processing time and hence time complexity (thereby increasing speed of encryption). It provides a comprehensive system functionality to be applicable in high level security application domain. Selective encryption is the technique of encrypting some parts of a compressed data file while leaving other part of plain text unencrypted. As security is an increasing public concern these days, encryption is becoming popular for communication any type of sensitive information. An effective encryption scheme that saves the cost and time for data encrypting will be the need of the government, organizations, business companies or individuals.
