Laboratories in colleges are used to give lectures to students, but what about after working hours? Students can get many benefits from these labs after working hours. For example, students can study and do their homework after working hours. In this project, we have proposed a new technique to control the access of these laboratories. Our idea is to use an encrypted QR code with an TOTP authentication that will be connected to LAN network to guarantee that each student enter can only use a single PC. Each student will have his own encrypted QR code that differs from other students. The TOTP code will be sent to student’s university email. The encryption method used encrypted method used AES encryption to encrypt the data inside the QR code to guarantee the confidentiality, integrity, non-repudiation, and authenticity of the date.
