The key technology of blockchain and its research in the field of information security

Abstract

with the rapid development of new technologies, such as the Internet of Things (IoT), big data and cloud computing and so on. The driving direction of science and technology is shifting to blockchain that is the underlying technology. China should take block chain as an important breakthrough of independent innovation of core technology. We should accelerate the innovation and development of block chain technology and industry. Combined with the key technology of block chain and frame model, this paper firstly analyzed the current information security situation. From two aspects of access control and data protection, author put forward to applications with block chain technology. And the framework model is form in the field of information security. It is helpful to develop direction of block chain.
