An Improved Security Approach Based on Kerberos for M2M Open IPTV System

Abstract

Open IPTV has attracted considerable attention and is expected to bring great changes in the IPTV service area. However, because of its openness and IP network characteristics, security is one of the major issues hindering its commercialization. For IPTV, several security mechanisms for user authentication and content protection have been applied to make the service reliable. These traditional security mechanisms cannot be adopted in the IPTV area, because in the many-to-many environment the security and hence the system performance is influenced by numerous factors. In our work, we propose a mechanism for secure user authentication and key distribution based on Kerberos for open IPTV and for secure M2M three-screen service in home networks. Our proposal provides an efficient authentication process and secure transfer of contents among users, and it further decreases the authentication time compared with the other mechanisms.

Intrusion Detection Prevention Systems and Performance Analysis via Internet Protocol Television (IPTV) using Snort Rule

“…In its performance and security, it limits users' requirements for breaking into the network of IPTV. Doh, I. et al [9] proposed using Kerberos, which is a protocol that verifies accuracy between a client and server via an entrusted third party with access to the open network environment. The third party provides the secret key to all clients and verifies its authenticity.…”

“…The copyright protection system [7] prevents the broadcasting of content due to piracy as well as unauthorized data transfers with a one-time password to log into the system [8]. Even the use of Kerberos [9], a protocol used to verify accuracy between a client and server, is not enough for prevention and verification because the current patterns of attack and terrorism on the internet have different severity levels. Some attacks may steal information, but do not affect the overall system.…”

Authentication and Key Management Based on Kerberos for M2M Mobile Open IPTV Security

“…We proposed a user authentication and key establishment mechanism in our previous work (Doh et al, 2013b). In this subsection, the proposed security mechanisms based on Kerberos are briefly reviewed.…”

“…Our proposal combines an authentication mechanism operating in a distributed environment, Kerberos, and modified CAS for IPTV. In our previous work (Doh, Lim, Chae, & Chung, 2013b); we proposed a user authentication mechanism and key distribution system for basic open IPTV services. It involves communication for static IPTV devices in a single domain.…”

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

“…Their scheme aims to provide contents to subscribers according to subscriber attribute. In [19] the authors proposed secure authentication approach based on Kerberos for M2M Open IPTV system where they introduce key distribution based Kerberos. The authors claim that their proposal provides an efficient authentication process and secure content transfer among users as well as decreasing authentication time.…”
