A Lightweight IoT Security Protocol

International audienceThe IoT is a technology that enables the inter-connection of smart physical and virtual objects and provides advanced services. Objects or things are generally constrained devices which are limited by their energy, computing and storage capacity. A Wireless Sensor Networks (WSN) is a network composed of devices managed by a CPAN (Personal Area Network Coordinator). The network is used in order to gather and process data of a given environment. It is characterized by their low bit rate and low power consumption, and it uses small size packet in their transmissions. In order to protect the WSN, a mutual authentication between devices is required during the association of a new device. The exchanged data should be authenticated and encrypted. In this work we propose a robust, lightweight and energy-efficient security protocol for the WSN systems. The real tests we made and a performance evaluation of our security protocol are provided

Survey of Security in Home Connected Internet of Things

Security and privacy have been increasingly important issues, especially surrounding privacy in consumer\u27s homes. Internet of things devices, while providing opportunity, also provide danger through poor or inconsistent implementation of security protocols or hardening techniques. Security research around home connected internet of things devices must then have more significant and summative research and literature to combat these dangers. This paper presents an overview of existing research focusing on internet of things devices intended for consumers in the home, discusses some specific case studies of vulnerabilities in existing and common devices, overviews some best practices as they\u27re suggested in various papers, and finally adds some discussion on interesting solutions to security in the connected internet of things home. This paper finds that many home connected internet of things devices are lacking minimal security, and that both consumption and production of home connected internet of things devices require a security focus in order to provide a stable foundation for this rapidly proliferating infrastructure
