Secure Shell Remote Access for Virtualized Computing Environment

Information processing in the era of big data is inseparable from the effective support of scientific computing. Complex scientific computing requires cloud computing to provide computing resources. One of the core foundations of Cloud computing is secure and reliable remote access technology. Users often log in to the remote server for scientific calculation. However, when users log in with public key, the steps are cumbersome. Therefore, this project develops a secure shell remote access information system for virtualized computing environment, which is called SSHRA for short. The system enables users to log in to the remote server more conveniently. The system can generate the corresponding certificate according to the public key provided by the user. Users use certificates for remote login. Users can obtain certificates through web or email. In addition, this system also designs an intelligent connection between multi hop servers. The system improves the security of remote login by limiting the IP, validity and available commands of the certificate. After users log in to the remote server with the certificate provided by the system, they can use commands to perform related operations. The system is developed based on open source software, so it has good scalability.
