AES and MQTT based security system in the internet of things - 2020

Aes And Mqtt Based Security System In The Internet Of Things

Research Area:  Internet of Things


Internet of Things grew rapidly over the last few years, the focus on security has not been kept up. In today’s world, smart city has developed as a contemporary paradigm to dynamically optimize the resources in cities and serve better facilities and excellence of life for the citizens. In this paper, a model is proposed using Advanced Encryption Standard-256 and Secure Hashing Algorithm-256 to attain the security in the IoT system. The data collected from devices is first encrypted using AES-256 with a symmetric key that has been created by using SHA-256 and finally the ciphertext is created. Now, this ciphertext is added to a new layer of security called Message Queuing Telemetry Transport protocol, which is an ISO standard (ISO/IEC PRF 20922) publish-subscribe based model used for the secure transmission of data. On the receiver side, the original data is extracted. In this way, three- layer security has been added to data collected by smart objects before transmission.
