Quantum computers have been around for a while, but the international cryptography community has "prepared for the rain" to prepare for the impact of quantum computers. On the 6th, the 6th International Conference on Quantum Security, hosted by the European Telecommunication Standardization Association, opened in Beijing. At the meeting, Jing Jiwu, deputy director of the Institute of Information Engineering of the Chinese Academy of Sciences, said that China will carry out standardization of anti-quantum cryptographic algorithms around 2022, and commercialization will be implemented around 2025.
The so-called anti-quantum cryptography algorithm is the quantum computer. The unit of information of a quantum computer is a quantum bit. Unlike classic computers, qubits can represent "0", can also represent "1", and can also represent the superposition of "0" and "1". Based on this feature, the computing power of quantum computers can far exceed that of classical computers. Thus, in the face of quantum computers, the walls built by traditional encryption algorithms appear to be “slowing the windâ€.
"Someone has played an analogy. Now there are algorithms and vocabulary, but the abacus has not yet been made." Jing Jiwu said that there is no "abacus", and it does not prevent you from building a shield for defensive quantum computers based on mature quantum theory. ".
Earlier, the public heard that more concepts might be quantum communication. China has already completed the construction of the kilometer-level quantum security communication trunk line "Beijing-Shanghai trunk line". So, with quantum communication, why should we emphasize anti-quantum cryptography algorithms?
Xiang Hong, director of the Key Laboratory of Information Physics and Social Trustworthy Service Computing of the Ministry of Education of Chongqing University, told the Science and Technology Daily that the quantum communication currently being implemented in engineering in the world is essentially the key distribution for traditional encrypted communication. The principle of quantum key distribution is that the sender and the receiver use a single photon state as the information carrier to establish key agreement. Based on the principle of quantum physics, single photons are inseparable, non-reproducible, and cannot be accurately measured. In theory, it can be guaranteed that a key can be stolen if someone eavesdrops.
However, the realization of quantum key distribution requires the establishment of a specialized quantum communication network, which is expensive and cannot be used to replace the existing Internet. Therefore, the future quantum key distribution will be used together with the anti-quantum cryptographic algorithm to protect information security. The former can be used in high security areas such as finance, while the latter can provide commercial encryption and personal authentication services.
In the international competition of quantum communication, China is at the forefront; but in the field of anti-quantum cryptography, there is still a gap between China and foreign countries. "The current gap is about a decade." Xiang Hong said that to do a good job of anti-quantum cryptographic algorithm research, what is lacking in China is talent, especially the lack of compound talents who are proficient in mathematics and quantum physics.
Jing Jiwu said that China has no real original results in anti-quantum cryptography algorithms, and basically is doing tracking research. However, he personally believes that China can make anti-quantum ciphers and cryptographic modules around 2020, and in 2022, it will launch a standardized procedure against quantum cryptography.
Previously, the National Institute of Standards and Technology of the United States collected anti-quantum cryptography algorithms for the world. Of the 82 algorithms received, 13 were eliminated before the first round of publication. Of the remaining 69 algorithms, there are currently 5 Was broken and withdrawn. “The Chinese team also submitted three algorithms.†Jing Jiwu said. The purpose of the collection algorithm is to select the algorithm standard.
Zhang Pingwu, director of the Commercial Password Management Office of the National Cryptography Administration, pointed out at the conference that the Chinese password was on the international standardization stage late, but it has already emerged in the international password standardization activities. He revealed that the "Safety Requirements and Evaluation Methods for Quantum Key Distribution Equipment" proposed by the Chinese research team has successfully entered the NWIP (New Work Project Proposal) voting stage at the ISO/IEC JTC1 SC 27 Norway Conference, which ended in early October. "We will continue to provide policy support for technological innovation and industrial development including quantum computing, attract more attention and invest in Chinese quantum and anti-quantum cryptography research, and promote the implementation of quantum cryptography applications with Chinese characteristics. Zhang Pingwu stressed.
