Description
Summary:	This paper proposes a real time implementation of a smart key which is a Wi-Fi based device that helps to lock/unlock all kinds of doors. Internet access allows to control doors all over the world by a simple mobile application. The app developed can be used in two modes ADMIN and GUEST mode. The ADMIN mode is protected by pin/password and is encrypted by the Advanced Encryption Standard (AES) algorithm. The password can be stored in the Key store and it can be changed whenever required. The ADMIN mode has the privilege to authenticate the GUEST mode to access all doors. For GUEST mode authentication, guests have to request the admin by using the app. Firebase is used as a server where the device and the mobile app are connected to it. Firebase is fast and accurate and hence can be accessed quickly. The main advantage of this proposed method is that it is fully operated through Internet so it can locked/unlocked wherever from the world. Comparative analysis is taken for three algorithms i.e., AES, DES and 3-DES and AES algorithm has given the best results in terms of execution time and memory usage and is implemented in the hardware lock. The experimental results give the screen shots of the app in guest and admin mode, firebase data and hardware real time implementation of the smart lock on a door.
