OMA DRM-Based Key Management Protocol for IPTV

Abstract:

Nowadays, with the development of hardware platform, digital content can be presented in more varieties of forms. The authorized users not only watch the authorized TV programs, but also are willing to do it via mobile phones and I-pad. Although the contemporary OMA DRM system provides an approach named domains to adapt multi-screens and services about the authorization of offline digital content, standard PKI procedures used to authenticate the DRM Agent, with the calculation and power consumption relatively larger, are not beneficial for the mobile terminal. Meanwhile, as the public key distribution is complex and the authorization is difficult, it is also not helpful for applied environment of multi-screens. Based on the authentication of hardware devices, the uniqueness of hardware ID also cannot meet the actual demand of multi-screen user. In this paper, we will propose a new protocol of key distribution based on OMA DRM. The protocol meets the requirements of low power consumption and multiple-screen, while providing the feasible security.
