Laboratory remote access control method

Abstract

The invention relates to a remote laboratory access control method. The method is characterized by comprising the following processing steps of: 1, carrying out authentication and authorization; 2, starting to keep an account; and 3, finishing the account keeping. The invention is reasonable in design, the authentication, authorization and account keeping functions between a user and an experiment table of a remote laboratory are realized by virtue of coordinative control among core control equipment, authentication, authorization and account keeping equipment, database equipment and terminal control equipment so as to realize remote access control on the laboratory, and the method in the invention has the characteristics of various functions, high safety and reliability, wide application range and low cost.

Description

technical field [0001] The invention belongs to the field of information technology, in particular to a laboratory remote access control method. Background technique [0002] Remote laboratories are of great significance in solving the contradiction between the substantial increase in the number of students and the shortage of experimental funds, the exploration of new experimental teaching models, the sharing of valuable experimental equipment, and the cross-city and cross-country cooperation between different universities or research units. The popularity of the Internet and the wide application of the Internet have laid a good foundation for the construction of remote laboratories. The existing remote laboratory control methods mainly include: [0003] 1. Use the SSL VPN of routers or multi-layer switches to realize user login and user abnormal logout monitoring. It uses SSL encapsulation technology to encrypt user login information, which can effectively prevent user l...

AI Technical Summary

Problems solved by technology

The problem with this method is that it needs to be completed on routers, multi-layer switches or servers with specified models and specified hardware configurations, and the cost is relatively high; the server side needs to add non-user login information traffic, that is, non-sensitive traffic for operating experimental equipment. , decryption processing, wasting bandwidth resources and hardware resources; client programs also need to perform data encryption and decryption processing, which has high requirements for client devices; cannot connect to virtual experimental equipment; cannot filter user operations; cannot record user operations; Accounting generally starts from logging in to the SSL VPN server device to logging out of the SSL VPN server device

The problems of this control method are: each set of test benches requires a terminal control device, which wastes equipment resources; cannot dynamically allocate test benches on demand; cannot connect to the virtual environment; cannot filter user operations; cannot record user operations

The problems of this control method are: the user cannot control the experiment time according to the experiment process; the experimental equipment is limited to the equipment of a specific manufacturer; the price is high, and the maintenance cost of the product provider is high; it is only used to connect the experimental equipment in the LAN; it cannot filter users Operation; Unable to connect to virtual lab device

[0006] To sum up, the existing control methods generally have problems such as high cost, narrow scope of application, and difficulty in realizing the authentication, authorization and accounting (AAA) function.
