Experimental analysis of two encryption schemes for security of video streaming

Abstract

With an exponential growth of multimedia and high speed internet, many relevant services and software are available for common person. Out of which, one of the applications is that common man wants to send multimedia data on internet. H.264 codec is used to compress this data by the systems. But data on the internet can be hacked, pirated or tampered with. Hence some security is required for multimedia data. In this paper, two schemes are provided for securing the video streaming after compression. One is with the proposed algorithm and the other with the standard algorithm(AES). In the second scheme, FMO is applied to bitstream which adds error resilience to the data. Both the schemes are applied selectively to I frame only of AVC/SVC. Performance is evaluated by finding PSNR for quality measurement. Also overhead bit and encoding time are compared. Security is discussed for some attacks. After considering the results for PSNR and discussion for other parameters, it is concluded that the second encryption scheme is much better as compared to the firstone.
