Analysis on the application security and technology of electronic signature

With the rapid development of information technology , Electronic signature is an important tool of digital office system , The scope of application is growing , More and more industries are involved . At present, the standardization of electronic signatures is not perfect , Security is worrying , The combination of cloud encryption technology and electronic signature technology will definitely promote the migration of electronic signature to the cloud , Promote the development of password ubiquity and security service . therefore , From the standardization of electronic signature 、 Application of electronic signature under security and cloud cryptography 3 Analyze the security and technological development of electronic signature application at three levels , The design idea and direction of current electronic signature products are put forward , In order to provide technical reference for the design of electronic signature application products .

With the country in e-government 、 Electronic Commerce 、 E-finance 、 Electric power 、 energy 、 signal communication 、 traffic 、 Scientific research 、 Online education 、 A large number of informatization construction in the application fields of network medical care and social security have been carried out , The basic network architecture is gradually taking shape , Various trust service systems are being gradually built , Corresponding technical specifications 、 Construction specifications 、 Testing specifications are also being developed and improved .

Electronic signature is an important infrastructure in the network trust service system , It represents authority and credit , It is an important part of information construction . basis 《 Law of the people's Republic of China on electronic signatures 》, The validity of electronic signature has legal basis , The application of electronic signature based on electronic signature technology has developed rapidly .

With 5G Promotion of network construction , The future will be an interconnected world , Will promote cloud computing 、 big data 、AI、 The development of industrial control and Internet of things , And change the production and lifestyle of all walks of life . Electronic signature is an infrastructure of digital office system , In e-government 、 E-commerce will be further widely used , It will also put forward new requirements for electronic signatures . The author from the standardization 、 Application of electronic signature under security and cloud cryptography 3 On every level , Analyze the security technology of electronic signature , In order to provide technical reference for developers .

01 Standardization of electronic signatures

At present, electronic signature products have been widely used in many industries , However, the design and application of electronic signature technology in products are generally not standardized , At the same time, there are different degrees of safety defects , Unable to meet the requirements of a truly qualified electronic signature system .
