Title: Asynchronous Communicationsfor the Space Internet

Abstract:
Internet protocols assume a synchronous operation: a client connects, exchanges information, and disconnects. Possibly due to its origin based on telephone infrastructure, it could be argued that the Internet has limits. These become apparent when thinking of the Internet in an interplanetary context: propagation delays and the occlusion of the planets force an asynchronous approach, more akin to postal mail than telephone. This motivates an area of amazing scientific-technological research -and at the same time challenging-, which also spreads in applications in near space, to so-called Ring Road Networks, and Sparse Direct-to-Satellite IoT networks, which will be revised in this talk.

Title: A lightweight key management scheme in IoT-enabled WSNs

Abstract:
Wireless Sensors Networks (WSNs) have gained a lot of interest over the last decade because of their use in several Internet of Things (IoT) applications such as building monitoring, health-care, smart cities, intelligent factories, … etc. To secure communications in these networks with cryptographic techniques, key management play an essential role. Sensor nodes, that compose WSNs, have resource-limitation in term of energy, storage and computation capabilities. For these reasons, an asymmetric cryptosystem is not advisable for its resource-consuming. However, symmetric cryptosystems have a reasonable resource-consuming which make them well adapted for WSNs but requires a key management system to distribute, maintain, refresh and revoke pairwise keys between sensor nodes. In this talk, I begin by presenting some related works on key management in WSNs and/or IoT-based WSNs. After that, I describe our contribution called SKM for sequence-based key management to solve the key management problem in IoT-enabled WSNs.

Speaker bio:
Mohamed-Lamine Messai is currently an associate professor at the University of Lyon 2 and a member of the SID research team of ERIC laboratory. Before, he was an associate professor at CPE Lyon engineering school for 2 years. He received his Ph.D. in computer science from the university of Bejaia (Algeria) and the university Claude Bernard Lyon 1 in 2016. He got a « Magister » degree from the university of Bejaia and an engineer degree in artificial intelligence from the university of Sétif. His main research interests are secure data collection, key management in resource-constrained networks and graph database analytics for cybersecurity. He is looking for challenging issues related to the secure machine learning.
