A smart home can be defined as a connected home, equipped with smart and connected devices and objects, which have the ability to communicate, interact and exchange with each other and with other IT devices through specific communication protocols, allowing remote access, monitoring and control of the home in order to increase the well-being, comfort and security of its inhabitants. Remote control of connected devices in real time and in a secure manner without fear of data breach is one of the serious issues in the implementation of a Smart homes/Smartphones (SHSP) system. The implementation of such a system requires a careful design that takes into account not only the electronic devices and their functionalities, but also the process of secure data exchange between the different components of the SHSP system. The major challenges of this implementation are the development of a mobile application for the user, the secure exchange of data in real time and the respect of the confidentiality of the shared data.
