A DRM model based on proactive secret sharing scheme for P2P networks

The development of P2P technology has brought a significant revolution to Internet, which effectively improves data-sharing in networks. However, it also enables piracy products to spread quickly all over the networks. Therefore, it is urgent to design digital rights management (DRM) for P2P network. Recently, many DRM products for P2P have been investigated, but there are some disadvantages. A new DRM model based on proactive secret sharing scheme is proposed in this paper. This verifiable DRM model ensures the validation of sub-keys. The model enables the users to obtain the key effectively and utilize the advantage of P2P networks.

Research of scheduling strategy based on rendering pretreatment mechanism

The computing resource of animation-based rendering based on WAN are distributed, heterogeneous, dynamical, so resource management and scheduling are challenging task, the performance evaluation, performance analysis and performance prediction have become increasingly important. In this paper, rendering pretreatment mechanism is introduced at first, then based on a detailed analysis of computing NRD (Node Reliability Degree) and multi-granularity segmentation for task, the resource scheduling strategy based on prediction is proposed, which provides a distributed solution for resource scheduling in distributed rendering environment.

Investigations on smart card-based secure protocols for autenticated key establishment in Digital pay-TV systems

Interactive TV is a promising technique to realize individualized services besides traditional video broadcasting, such as VOD (Video on Demand), Email on DTV (Digital TV), E-banking. Utilizing return channel (like Internet, mobile communication), many new applications can be established, which promote the value-added services of DTV. For more profound applications, security mechanisms must be deployed to protect the profits of both the content providers and subscribers. This paper presents investigations on the smart card-based secure protocol for user-STB authentication and session key establishment in DTV system. The proposed secure protocol has features of bidirectional authentication, session key secrecy, session key confirmation, forward security, and efficient interval restart, etc. Therefore, the protocol is appropriate for use on secure conditional access and can be referenced easily in future CA systems for value-added applications.

Investigations on Simultaneously Secure IBE Scheme and Security Proofs under RO and Non-RO Model

This paper analyses security mechanism and authentication, key agreement protocol of 3G system amply, puts forward a amelioration scheme. This scheme assures security communications without credible VLR. This paper analyses ameliorative protocol and resolves the security communications problem between MS and HLR.
