Auxiliary System for Contract Signing Based on Electronic Signature Technology

Abstract

With the rapid development of the Internet, a large part of people's work and life has been transferred to the computer. Now, the processes of file transfer and data storage in people's work are all completed by computers. In the process of working with computers, how to ensure the legality, traceability, antitampering, and uniqueness of documents is an important part of the development of computers. In order to ensure the security in the process of electronic contract authentication, this study has carried out a detailed analysis and design of electronic signature technology. In this study, PKI technology and USB Key technology are combined, which effectively prevents the tampering of electronic signatures and electronic seals in electronic contracts. This study uses PKI technology to strengthen the application and distribution of electronic seals and achieve the purpose of copyright protection of digital media. The improved electronic signature technology in this study can improve the security of signing electronic contracts at work and make users' electronic signatures indestructible and noncopyable.
