A RANDOMIZED SELECTIVE ENCRYPTION USING HASHING TECHNIQUE FOR SECURING VIDEO STREAMS
Journal Title: International Journal on Computer Science and Engineering - Year 2012, Vol 4, Issue 11
Abstract
Digital video transmissions are widely used in network nowadays. Hence, securing its contents and keeping privacy is vital. Several encryption algorithms have been proposed earlier to achieve secure video transmission. But altogether attaining efficiency, security and flexibility is a major challenge. To transmit a digital video, encryption is necessary to protect its contents from attacks. As the size of the videos are usually large their contents has to be compressed before transmission. Encryption is applied on the video content after compression. One of the encryption technique selective encryption is used for encrypting video. It encrypts only a subset of data. The selective encryption algorithm reduces the amount of the data to be encrypted and achieves a required level of security. In this paper we study the existing selective encryption algorithm and its classifications. The challenges in the selective encryption algorithms and some future directions are presented.
