Secure Communication of Cloud and IOT using Lightweight Key mechanism

Internet of Things is the new technology in the field of telecommunication. IoT is progressing in the wireless, remote communication. In IoT all the smart devices create a network send and receive data through the Cloud. IoT smart devices communicate with Cloud always. In this Cloud IoT environment challenges identified are device battery life, storage space, and power consumption of smart device, security of the data exchanged between Cloud and IoT smart devices. In this paper we discuss the design and implementation of secure communication of Cloud and IoT using Lightweight Key mechanism. We have used Symmetric Lightweight Algorithm for Cloud IoT Security. We have used Advanced Encryption Standard (AES) to speed key setup time. The integration of Cloud and IoT Security with the help of AES algorithm performs effectively and consistently in both software and hardware platforms for various environments. With the help of this integration, we can use Cloud IoT services to connect various smart devices and sensors so that the sensor readings are shared with others by reducing the security challenges. We have securely authenticated cloud server and IoT smart device before the communication or transfer of data gets started and also, we have generated different session keys for every new session or handshaking between them. Finally, we discuss the Cloud Computing contribution in IoT technology for the secure communication by overcoming some security challenges.
