Secure and Guarantee QoS in a Video Sequence: A New Approach based on TLS Protocol to Secure Data and RTP to Ensure Real-time Exchanges
Authors: , ,
Abstract: The continued development of networks has significantly contributed to increasing the quantity of
information available to replace old intelligence-gathering methods faster and more efficiently. For this, it is
necessary to implement services that meet the consumers' requirements and measure precisely the factors that
can generate obstacles to any communication, among these causes we can cite strong security and high quality
of services. In this work, we implement a secure approach useful in continuous communications in a time axis
(video sequence, VOIP call...), the process consists in establishing a well-secured connection between two
interlocutors (the server that broadcasts the video sequence and a client) using an AES encryption key of size
256. A step of jitter check (latency variation) periodically is essential for the customer in order to make a
decision: If the jitter is within the standards (compared to the tolerable value), we continue to encrypt with the
AES256 key, if no, both ends must go through an automatic and uninterrupted fast renegotiation of the video to
switch to a small AES key (192,128) to reduce the bandwidth on the channel, this operation must be repeated
in an alternative way until the end of the communication.
