In recent years, the rapid development in the field of wireless technologies leaded to appear a new topic known as the Internet of things (IoT). The IoT applications can be found in various fields of our life such as smart home, health care, smart building, and etc. In all these applications the data collected from the real world are transmitted through the Internet, therefore these data have become a target of many attacks and hackers. So, a secure communication must be provided to protect the transmitted data from unauthorized access. This paper focuses on designing a secure IoT system to protect the sensing data. In this system, the security is provided by the use of Lightweight AES encryption algorithm to encrypt the data received from physical environment. The hardware used in this proposal is the Raspberry Pi 3 model B and two types of sensors. The LAES algorithm was embedded inside the Raspberry in order to protect the sensing data that comes from sensors connected to the Raspberry Pi before sending it through network. The analysis results show that the proposed IoT security system consumes less time in encryption/decryption and has high throughput when compared with others from related work. Its throughput is higher in about 19.24% than one system from the related studies.
