| With the gradual development of archives informatization and digitalization,electronic archives,which are mainly based on the original electronic files and archives digitization achievements,have become the main form of archives.The following is the change of archives management mode.Network storage and network utilization improve the remote service ability of archives,while providing convenient services for users,the safety risk of electronic archives is also increasingly prominent.Especially in the use of archives,due to the nature of electronic archives easy to modify and the openness of the network system,electronic archives in the physical layer,link layer,network layer,transport layer,application layer of the network structure are facing many threats,these threats lead to electronic files can easily be illegal intercepted,copied and destroyed in the process of using,and thus resulting in the leakage and loss of archives information,and bring to the safe use of electronic archives a lot of obstacles.At present,the technology to ensure the safety utilization of electronic archives mainly include authentication and identification technology,firewall technology,intrusion detection technology,anti-virus technology,information encryption,digital signature technology,etc,these technologies from different levels and angles build a protection barrier for the safe use of electronic records,to a certain extent,solve the security issues in using electronic file.However,due to the limitations of traditional technology and the rapid improvement of computer capabilities,these encryption and protection methods based on traditional algorithm are increasingly facing the risk of being cracked,and the safe utilization of electronic archives is still facing great challenges.Quantum communication is a new interdisciplinary subject developed by the combination of quantum mechanics and classical information theory.It makes full use of the Heisenberg uncertainty principle and the quantum non-cloning theorem to realize unconditional secure communication which can be proved,which is regarded as an important technical foundation to guarantee the future information security.At present,the main contents of the research on quantum communication technology at home and abroad are focused on quantum key distribution,quantum teleportation,quantum security direct communication,quantum secret sharing and so on.All countries in the world have paid great attention to quantum communication.The European Union,the United States and Japan have all proposed the development plan of quantum communication,and the competition around quantum communication technology is also increasingly fierce.On the basis of accelerating the research of quantum communication technology,all countries have established various quantum communication security networks,providing a larger platform for the verification and application of quantum communication technology.In the future,with the breakthrough of the difficulties in the quantum communication technology and the improvement of the infrastructure construction,the quantum communication will have a wider application prospect.Absolute security features of quantum communication makes it become the best choice to maintain the safe use of electronic archives,and the security based on quantum mechanics principle,not rely on traditional computing complexity,not affected by computer capability and technology lag,therefore the quantum communication technology can break the limitations of the traditional technology and provide the most effective technical support for the safe utilization of the electronic archives.In addition,by using the characteristics of quantum communication,such as super channel capacity,ultra high communication rate and ultra long distance transmission,we can improve the efficiency of secure transmission of electronic files and achieve efficient transmission of large capacity archives information.The application direction of quantum communication technology in the safe utilization of electronic archives is mainly concentrated in two aspects.One is that it can be used for identity authentication,the other two is for secure transmission.In practical applications,the decoy state BB84 protocol,which is more secure,mature and easily realized,is used as the basic scheme.The structure of secure communication system based on quantum key distribution is divided into three levels:QKD layer,key management and application layer.QKD layer generates security key through QKD protocol;Key management is responsible for managing the key between each node,and managing and controlling the network topology;The application layer sends and receives the raw data to be encrypted and decrypted.When conducting physical deployment,it is necessary to choose a single fiber as a quantum channel,and choose to construct point-to-point or multi-user quantum communication network.To make it easier to meet the needs of ordinary users,it is also necessary to develop a wider range of archival quantum networks to include more users.Although China has made brilliant achievements in quantum communication technology and application,but the wide application of quantum communication technology in the safe use of the electronic file still exist in the system performance needs to be improved,the cost of infrastructure is too expensive,the testing technology and standard are not normative and other obstacles.It is necessary to seek solutions from three aspects of technology,industry and standards,including increasing policy support and funding to mobilize scientific research forces to make technological breakthroughs;strengthening the construction of quantum communication infrastructure and promoting the industry layout of quantum communication;reinforcing cooperation in industry-university-research,and accelerating the development of testing technology and standard specification.The solution of these obstacles plays an important role in realizing the application of quantum communication technology in the safe use of electronic files.The solution of these obstacles plays an important role in realizing the application of quantum communication technology in the safe use of electronic files.In the important period of archival information construction,the safe utilization of electronic archives is an important goal related to the development of archival industry,and it can push forward the transformation of function mode of archives department and the transformation of utilization mode of electronic archives.As a newly emerging science power,the application of Quantum communication technology in the safe utilization of electronic files not only closely follows the trend of the times,but also responds to the call of the state to achieve a useful exploration of the safe utilization of electronic archives.The Archives Department,who have the higher requirements for archives information security,actively explore the application of quantum communication technology in the safe use of electronic archives not only is a very meaningful and forward-looking work,but also is an inevitable choice to maintain the security of the archives information and promote safe development of electronic archives.We also have reasons to believe that quantum communication technology will break the limitations of traditional technology and create unprecedented opportunities for the development of electronic archives in the process of transforming traditional archives into digital archives. |
