Using Cryptographic Algorithms to Create a Temporary Pass Using QR Code Generation Technology

In modern conditions, the security of higher education institutions requires an integrated approach, including both physical protection and cybersecurity. With the growing number of students, faculty, and visitors, as well as increasing threats such as terrorism, vandalism, and cyberattacks, the implementation of effective access control systems is becoming an urgent task. One of the promising solutions is a system for monitoring temporary passes based on QR codes, which ensures not only the restriction of unauthorized access, but also the collection of data on the movement of persons on the territory of the educational institution. The purpose of this study is to develop a methodology for using QR codes in access control systems of higher education institutions using modern cryptographic algorithms, including symmetric encryption (AES-256), asymmetric elliptic curve cryptography (ECC).The essence of the proposed solution is an automated system that includes: electronic applications for admission; automatic; QR code generation.codes with encrypted data; control of the validity period of passes; monitoring violations and integration with the Telegram bot for the convenience of users. The principle of the described technique is based on the encryption of the metadata of the pass, followed by the generation of a QR code that can be read and verified by the security service. AES-256 and ECC algorithms are used to ensure a high degree of protection.The scientific novelty of the solution lies in the combined use of QR codes and modern cryptographic methods, which ensures a high level of security and ease of use in a university setting.The theoretical significance of the work consists in developing a model of an access control system adapted for educational institutions, taking into account modern threats and requirements of regulatory documents (for example, Decree of the President of the Russian Federation No. 166 dated 30.03.2022).The practical significance is confirmed by the possibility of direct implementation of the system in educational institutions. The solution allows not only to increase the level of security, but also to optimize administrative processes by automating the issuance of passes and integrating with the Telegram messenger.
