China's quantum confidential communications usher in another breakthrough in the field of China Electronics Technology Group on the evening of 4 released a new high-speed quantum random number generator, quantum random number real-time generation rate greater than 5. 4G bit per second, the limit exceeded 117G bits per Sec, refreshing the 68G bit per second recorded by the team of China University of Science and Technology, making it the fastest quantum quantum random number generator in the world.
According to the basic principle of password design - 'all the secrets in the key among the'. China Electronics Technology Group Network Security Company Chief Engineer Rao Zhihong introduced the key is the foundation of password security, and the key to produce the quality of how efficient, Depends on the technique of generating random numbers, that is, the performance of the random number generator is good or bad.
Generally speaking, the higher the rate of random numbers, it means that more keys per unit time can be generated to achieve a true 'random key,' so that those who attempt to steal confusion, no 'key' Available, it is difficult to quickly find the key to crack the password in secure communication and theft, with the perfect theoretical security. 'Rao Zhihong said.
Communication security is the cornerstone of national information security and economic and social activities, but how to ensure the security of communication is also a worldwide problem.It is generally accepted in the industry that quantum confidential communication technology can perfectly solve information as an 'unconditional and secure' means of communication security The security issues in the transmission process have become the core of a new generation of information network security solutions.
As one of the core devices of quantum secure communication, the development of quantum random number generator has been paid attention by the industry.Xu Bingjie, one of the project leaders and a senior engineer of China Electronics Technology Group Network Security Company, said that the high speed quantum random number The generator has the features of 'true randomness, super speed, miniaturization' and so on. It has obtained 5 patents for invention. Its output bit rate of quantum random number is 3 to 4 orders of magnitude lower than the traditional technology, Used in quantum communication industry and information security industry.
