IPTV Service Framework Based on Secure Authentication and Lightweight Content Encryption for Screen-Migration in Cloud Computing

Abstract EN

These days, the advancing of smart devices (e.g.

smart phones, tablets, PC, etc.) capabilities and the increase of internet bandwidth enables IPTV service provider to extend their services to smart mobile devices.

User can just receive their IPTV service using any smart devices by accessing the internet via wireless network from anywhere anytime in the world which is convenience for users.

However, wireless network communication has well a known critical security threats and vulnerabilities to user smart devices and IPTV service such as user identity theft, reply attack, MIM attack, and so forth.

A secure authentication for user devices and multimedia protection mechanism is necessary to protect both user devices and IPTV services.

As result, we proposed framework of IPTV service based on secure authentication mechanism and lightweight content encryption method for screen-migration in Cloud computing.

We used cryptographic nonce combined with user ID and password to authenticate user device in any mobile terminal they passes by.

In addition we used Lightweight content encryption to protect and reduce the content decode overload at mobile terminals.

Our proposed authentication mechanism reduces the computational processing by 30% comparing to other authentication mechanism and our lightweight content encryption reduces encryption delay to 0.259 second.
