Description:	Internet of Things (IoT) rises as a powerful domain where embedded devices and sensors can connect and exchange information over the Internet. IoT device has to connect to control station in order to forward collected data and obtain their data processed. Secure data exchange between IoT devices and other systems are required to prevent any attacks attempts that can lead to dangerous consequences. Authentication is a critical stage for efficient security level. The nature of IoT devices as a resource contains devices that require a special authentication schema that does not consume high computing and energy resources since IoT devices have limited energy and computing resources. These limited devices limit resources connected to the internet which expose these devices to huge number of attackers thus, making it vulnerable. Authentication is required to ensure security and identify identities to prevent attacker and malicious attacks. In this thesis, a novel authentication mechanism for IoT networks has been proposed. This mechanism mainly depends on Elliptic Curve Cryptography (ECC) algorithm over the Constrained Application Protocol (CoAP). The proposed authentication approach provides an efficient authentication mechanism with high security. Implementing ECC algorithm of small key with the light weight web protocol CoAP can minimize the computation and energy resource with powerful security features. CoAP can provide an efficient alternative for Hypertext Transfer Protocol (HTTP) for application traffic with minimized communication overhead. It can handle application communication in an asynchronous way. In addition, HTTP also provides lower communication overhead than CoAP with Datagram Transport Layer Security (DTLS) approach. It also provides efficient protection against most of common network attacks where traditional CoAP and CoAP with DTLS fail to provide reliable protection. The proposed mechanism adds only 3% bandwidth overhead over pure unsecure CoAP however it has a decreased bandwidth overhead of 28% than CoAP with DTLS. The delay of the proposed mechanism is 47% lower than CoAP with DTLS, however it adds only 0.4% to the traditional CoAP. In terms of consumed energy, it is adding only 1.6% to the traditional CoAP traffic energy consumption. However, DTLS consume more energy, which is around 25%.,Certification of Master's/Doctoral Thesis" is not available
