Secure Smart Home: Aplicações IoT residenciais seguras utilizando o protocolo TLS

This work describes a secure residential IoT (Internet of Things) application development using the transport layer security (TLS) protocol. The project integrates a mobile application and hardware modules, which allows for the control of air conditioning, internal lighting, and curtains. The Android mobile application controls the environment in which the hardware modules are located. Application and firmware communicate through a broker entity using the MQTT protocol (Message Queuing Telemetry Transport). Security aspects were provided by adding TLS protocol and authentication.
