Security mechanism of video content integrated broadcast control platform under triple play

Abstract

According to the new format of triple play, video contents interact in the integrated broadcast control platform, there are security risks and participation dispute liability trace ability problem, we propose an integrated control platform security mechanism under triple play. The mechanism builds a bit commitment protocol through hash function, preventing the video tampering in public network transport, using exchanged ElGamal encryption mechanism to achieve a confidentiality comparison in the event of a dispute, to trace the responsible party. Theoretical analysis shows that this method has good security and feasibility, and can effectively solve the security of video content in integrated broadcast control environment.
