Abstract: The privacy and security have been becoming the most exigent tasks in the Internet of Things (IoT) network. The worst enemy could be the IoT without the security and privacy policies. MQTT depends on TCP as per the transport protocol, and by default the encrypted communication is not being utilized by the connection. This paper investigates the approach of applying Advanced Encryption Standard (AES) for smart home communication in MQTT based IoT network. A prototype of network of smart homes is implemented and the data transmission reception is done using MQTT protocol. AES payload encryption with MQTT is done and the network is analysed for privacy and efficiency. Brute force attack is considered for testing the confidentiality and integrity of the data. The hardware setup of the network is implemented using Raspberry pi.
