Enhancing the Security of Iot Data Using Multilevel Encryption

Abstract

Internet of Things (IoT) plays a vital role in the field of Information Technology, Industries and Healthcare etc. As data in IoT applications will be related to the physical realm, ensuring data security is a primary constraint for many cases. Because in the IoT context not only users, but also authorized objects may access data.Security represents a critical component for enabling the widespread adoption of IoT technologies and applications. Therefore this paper proposes a multilevel encryption technique to enhance the security of the IoT data. In this approach the data sensed from the IoT devices are encrypted in the gateway using Merkle-Hellman encryption and Elliptic Curve Cryptography(ECC) to ensure the security of the data.
