Problems solved by technology

Although all walks of life have invested a lot in mental health surveys and even the privacy of student grades, students may not truly reflect their psychological status when making choices because they are worried about their personal privacy being leaked.
This also makes a lot of psychological research more difficult.

Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0038] Method of the present invention comprises the following steps:

[0039] A system design and implementation method for homomorphic encryption in student mental health investigation, comprising the following steps:

[0040]Step 1: The user purchases a key generator from the service provider. Assuming that the key generator is an external device similar to a USB flash drive, only the user holding the device can generate a key. The key generator has its own serial number. The user activates the key generator for the first time, then generates an identity authentication code, and sets a login password. The genera...

Abstract

The invention discloses a system design and implementation method of homomorphic encryption in student mental health investigation, and belongs to the field of symmetric key cryptography and public key cryptography. According to the method, firstly, a user uses a key generator to generate an identity authentication code, then, the user logs in a system to fill in a survey report, then, the system ensures full homomorphic calculation of a cloud end by using a full homomorphic algorithm (somewhat algorithm) constructed by a pallier addition homomorphic structure and an RSA multiplication homomorphic structure, and finally, the user inquires and detects a ciphertext result through a ciphertext index, and exports and decrypts by using a private key to obtain the mental health assessment. The student trust psychological health evaluation system can be guided to obtain a real test effect. Therefore, the system can meet the privacy protection requirement of mental health evaluation in an online environment, and the privacy right of the user is better protected. The method not only can be applied to the mental health evaluation level, but also has a good application prospect in various online surveys such as occupational attainment evaluation and the like.

Description

technical field [0001] The invention relates to the fields of symmetric key cryptography and public key cryptography, and in particular relates to the privacy protection application of fully homomorphic cryptography in the investigation of students' mental health. Background technique [0002] With the emergence of cloud computing, although it has accelerated the development of the Internet era, it has also brought new challenges to user privacy protection. These privacy leakage problems include privacy leakage at the client end and privacy leakage at the center of the cloud. . And this year, the problem of information leakage in the cloud service center has occurred from time to time, which has led to more and more users distrusting the cloud service center, especially unwilling to store their private information on the cloud platform. [0003] Although the conventional way of storing plaintext in the cloud can maximize the utilization of storage and computing resources, t...
