A novel idea of video encryption using hybrid cryptographic techniques

The concept of video encryption is growing in popularity mainly because of the increasing use of communication techniques such as video conferencing for carrying out business meetings and presentations. The video data that travels to and fro between the sender and the receiver has to pass through the most unsecure medium of communication, the internet. The existing methods for providing security to the video data relies mainly on heavy signal processing algorithms which require a lot of bandwidth and takes a lot of time to carry out the encryption resulting in lags in communication. On the other hand, no single encryption algorithm is secure enough to provide a completely flawless and lossless result. Symmetric algorithms are faster but easier to break into, whereas asymmetric algorithms are more secure but take longer time. The novel idea proposed in this article makes use of the advantages of both the methods by presenting a hybrid technique of encryption, resulting in a much secure and faster alternative of video encryption.
