 Leek heart pain this year, block chain industry has lost $1 billion 900 million due to safety problems.


Yu Kequn, the director of the national information technology security research center, 8, said in 2018 that the development of block chain technology may be an important step for China to master the global scientific and technological competition, which is the key to the realization of the overtaking of the curve in China. He also said that security is the future life of the block chain. The block chain is still in the primary stage, and there are many challenges such as the security of the cryptographic algorithm. The risk is not only from the external entity, but also from the attack from the internal participants. How to build a security system around physics, data, application system, encryption and risk control is an important problem at present. As a new integrated application of distributed data storage, point to point transmission, consensus mechanism, encryption algorithm and other technologies, block chain technology is considered as a new round of technological innovation and industrial change. It has special points such as centralization, openness, autonomy, tampering and anonymity. The block chain is also written into the 13th Five-Year National Informatization Plan. The Secretary General of Chinas cloud system industry innovation strategic alliance, Shen Yu, said that if the currency is the 1 version of the block chain, the expansion of the application of the block chain in the financial field is 2, while the extension to the real economy is the 3 version of the block chain. With the wide application of block chain technology in financial services, supply chain management, cultural entertainment, intelligent manufacturing, social public welfare and education and employment and other economic and social fields, it will reduce operating costs and enhance synergy efficiency, thus providing a systematic support for the transformation and upgrading of the economy and society. Shen Yu said it. Block chain technology as a new technology, security threat is one of the most important problems it faces. With the increasing value of information economy, attackers use various means of attack to acquire more sensitive data. Li Ming, the director of the research room of the block chain of the Institute of electronic industry and information standardization, believes that, from the standardised point of view, the block chain needs standard standards and security, and a real system and platform should be applied to the ground. In fact, it is not only the slogan of shouting, it needs the thought of system engineering to support it. Li Bin, assistant director of China Information Security Evaluation Center, said the security issues of block chain technology with safety as the core are attracting attention constantly. One line of code, overthrow a token, a loophole, the destruction of a class of intelligent contracts, the security risk of block chain technology needs the power of the whole society to face together. Yu Kequn said that because of the de centralization of the block chain, the system exposed in the public chain can not be shut down, the error repair is also very difficult, the application field is gradually wide, the block chain will evolve into the service of the technical infrastructure class, and the serious security consequences will result in the occurrence of problems. The report on the safety analysis of the block chain industry published by the Forum on the safety research of white hat sinks showed that the losses caused by safety incidents around the world from 2011 to April 2018 were as much as 2 billion 864 million dollars. The amount of loss has shown an exponential trend since 2017, and the loss has been as high as 1 billion 900 million US dollars since 2018 alone. Deng Huan, head of the white cap Security Research Institute, said the losses caused by block chain security vulnerabilities are billions of dollars a year, and attackers mainly choose to protect relatively weak contract layers and business layers, and the technology layer itself is the best realisation of the current attackers. The report shows that at present, attackers mainly use denial of service attacks, Trojan horse hijacking attacks, payment loopholes and other means to destroy the business layer. Block chain, as the underlying technology foundation, supports the whole system. If there are safety problems at the bottom, it will lead to the upper level affected. Therefore, safety design should be added at the beginning of the system design. Deng Huan introduced, in order to provide a better reference for the related enterprises, the block chain industry security website introduced at the same time will be divided into security events collection, event analysis, and block chain ecological monitoring, which will be analyzed and tracked for the whole block chain ecological security, and the industrial safety of the block chain will be updated regularly.
