Enhancing Security In Nebulae Framework

Abstract

Sensor nodes are widely used for automation. These sensor nodes communicate wirelessly with each other to form a wireless sensor network. As the sensor network performs a critical task in automation. This arises a security issue for sensor nodes communication. As the data during communication could be manipulated and send to the destination which may lead to huge loss of resources and environment. This thesis discusses about securing communication data for Contiki OS as it is one of the operating system used for sensor nodes. Datagram Transport Layer Security (DTLS) which provides features such as cookie verification, authenticity, integrity, and confidentiality for data communication. Thus DTLS implementation would help to solve security issue upto some extent. Implementation of DTLS on Contiki operating system and working flow of DTLS is been discussed in this thesis. NXP JN5168 microcontroller has been used as sensor node for hardware implementation.
