A DRM Scheme Based on Oblivious Transfer Protocol;

Secure Multi-party Computation(SMC) about which people have got some research findings at home and abroad has been a research focus in international cryptographic community recently,and this paper proposes a new protocol for the inverse of n×n matrices by using Oblivious Transfer 1 out of p protocol in the secure two-party computation environment.

Universally composable oblivious transfer protocol based on VSPH;

Analysis of oblivious transfer;

With a first two round string oblivious transfer,the protocol can avoid performing a large mount of bit oblivious transfers.

How to register and use transmission protocol in WinSock;

According to the theoretical analysis and test results,data transmission protocol for application layer is developed based on time-window strategy.

From the view of data management,this paper analyzes the character of data for vending machine based on network and makes the transmission protocol of the front data.

It’s concept and principles are illustrated,main formats of streaming media and it’s transport protocols are also analyzed,providing a frame project of streaming media service platform is provided.
