Lightweight Encryption Technique for Content Security in Open IPTV Environment

摘要

With the advent of open IPTV environment, a variety of IPTV devices have been developed. Open IPTV platform has a high degree of content utilization because it allows users to use various applications and services through diverse devices. Recently, many users watch IPTV using such mobile devices as smart-phone and tablet PC in the aforementioned open IPTV environment. On that account, it is required to develop a lightweight encryption technique in consideration of mobile devices when applying encryption/decryption for content protection. This thesis proposes the lightweight encryption/decryption technique that complemented the specific-hardware centric technique in the existing content distribution system. The performance evaluation confirmed that the proposed technique had a higher rate of encryption/decryption and also distributed contents more securely than the existing technique.
