摘要：Omnipresence of security in every application in Internet application is a clear motivation to contribute in the field of Information Security. Security is one of the most challenging aspects in the internet and network applications. Encryption is a process which is used to secure the data and the Encryption algorithms play a crucial role in efficient information security systems. Full encryption techniques are slow. Selective encryption is a technique to save computational power, overhead, speed, time. This technique also provides quick security by only encrypting a selected portion of a bit stream. Selective encryption technique is one of the most promising solutions to increase the speed of encryption as compared to the full encryption. Selective encryption is helpful for the multimedia content like images, video content and audio content. So this document discussed about Selective encryption technique which is used to increase the speed of encryption as compared to the full encryption
