Method and system for preventing cheating during examination based on trusted computing

Abstract

The invention discloses a method and system for preventing cheating during an examination based on trusted computing. The method and system are achieved based on a TCM credible encryption module, and security mechanisms such as credible guidance, dynamic integrality measurement, credible network connection, asymmetric encryption and decryption and digital signature verification are used. Security guarantees provided by the method and system for an examination scene include the platform security before the examination, the network connection security between a client side and a server, the security of the system environment during the examination and the like, the integrity of an examination operation system and the integrity of an examination system are protected in real time, and cheating behaviors achieved by running malicious software and the like are prevented. By the adoption of the method and system for preventing cheating during the examination based on trusted computing, answers of an examinee are prevented from being tampered on the server side due to collusion between a server administrator and the examinee.

Description

technical field [0001] The invention belongs to the technical field of network education, and relates to a method and system for preventing cheating in exams, in particular to a method and system for preventing cheating in exams based on trusted computing. Background technique [0002] With the development of the Internet and the diversification of education forms, many examination institutions and educational institutions use online examinations to assess students. In the process of online examinations, in order to ensure the validity of online examinations, we need to prevent candidates from cheating as much as possible, and ensure that the confidentiality and integrity of test papers and answers submitted by candidates are not destroyed. Setting up an invigilator in the examination room of the online examination can eliminate traditional cheating methods such as substituting for the test in the traditional examination and whispering in the examination room. However, it i...

Problems solved by technology

However, it is impossible to prevent cheating behaviors such as using the test machine for network real-time communication or running illegal software.

The anti-cheating measures in the existing examination system include using the lock screen to prevent candidates from starting other programs, using network monitoring to prevent candidates from using real-time transmission tools, etc.

But these security measures rely purely on software and are easily bypassed and compromised

In addition, the existing work is difficult to prevent the following cheating behavior: Candidates collude with the administrator to tamper with the submitted answers stored on the server after the exam
