Abstract
In this paper we present the advantages of the elliptic curve cryptography for the implementations of the electronic signature algorithms “elliptic curve digital signature algorithm, ECDSA”, compared with “the digital signature algorithm, DSA”, for the signing and authentication of H.264 compressed videos. Also, we compared the strength and add-time of these algorithms on a database containing several videos sequences.
Highlights
The media industry has witnessed a phenomenal and unprecedented explosion in the recent decade
We give the results of the comparison we do between DSA and ECDSA used for the signing of large number of H.264 video
Experimental results are given to demonstrate the benefit of using the ECDSA based on the elliptic curve cryptography
Summary
The media industry has witnessed a phenomenal and unprecedented explosion in the recent decade. The multimedia information including video data has some special characteristics like high capacity, redundancy and high correlation among pixels which leads us to choose the type of video encoding on which we will work. This brings us to use H.264 given the advantage that provides this type as size standpoint and video quality [3]. We compare the implementation of the most known two signature algorithms DSA, digital signature algorithm, and ECDSA, elliptic curve digital signature algorithm [4]-[5] As this type of data requires memory space, the process of electronic signature is not used directly on the video but rather on what we call the hash of this one.
