Executing large-scale processes in a blockchain

Purpose The purpose of this paper is to examine the blockchain as a trusted computing platform. Understanding the strengths and limitations of this platform is essential to execute large-scale real-world applications in blockchains. Design/methodology/approach This paper proposes several modifications to conventional blockchain networks to improve the scale and scope of applications. Findings Simple modifications to cryptographic protocols for constructing blockchain ledgers, and digital signatures for authentication of transactions, are sufficient to realize a scalable blockchain platform. Originality/value The original contributions of this paper are concrete steps to overcome limitations of current blockchain networks.

The Study of Network Information System Security Strategy Based on Trusted Cloud Computing

This paper analyzed functions of the network information system based on trusted computing and trusted computing platform based on cloud computing. Raised the propose to expand the application of trusted computing technology to network information system, to meet the needs of cloud computing of trusted computing, trusted cloud computing, implement the trusted cloud computing. In our design, will take the Trusted Computing Platform (TCP) as the basis of cloud computing system, provide some important security functions to ensure the communication and data security.Finally put forward the implement methods.

The Implementation of Trusted Computing Based Network Trusted Management Information System

In this paper, the application of Trusted Computing Platform is discussed. It is pointed out that the purpose of network management information system by trusted Computing platform is to set up a trusted network system. Based on the analysis of the environment of the trusted network information management system, we employ a trusted computing model in the information system of graduate student at our university. The implementation of network trusted management information system indicates that this method will improve the security of information system.

A Layered Trusted Computing Platform Module with Unified Deployment on Server

This paper discusses the trusted computing model which is based on existing computer network. The present trusted computing platform has to make big changes on personal pc hardware system in order to realize the trusted computing platform module on pc mainboard or hardware. To solve this, here presents a layered trusted computing platform module, which replaces the original trusted computing platform module with implemented modules on server. The prototype model ensures the trust measurement being implemented on any logical layers of the trusted platform with making a complete trust chain from the beginning of the boot stage of the client operating system. By creating a trusted computer platform with all the computers in the system, real trustworthiness in the entire local area network can be realized.

Research of Secure Sharing of Electronic Medical Records in Internet

Regional sharing in electronic medical records (EMR) system are the main problems that the system must face in the development. This paper comprehensive analyzes the existing secure sharing program of EMR, and based on it this paper proposes the program that uses the Trusted Computing technology to ensure the secure sharing of EMR. For ordinary computer can not build trusted computing platform, the embedded trusted system based on the USB interface is used to build trusted computing platform, and based on it this paper proposes the EMR secure sharing scheme based on the embedded trusted system.
