Virtual laboratories are fully interactive simulations in which students conduct experiments, collect data and answer questions to assess their understanding. The primary objective of virtual cloud-based lab solutions is to provide customized IT environments for users. In today's information, networks and security training, time and location are one of the crucial elements for participants. Many universities...
The main objective of the work is to enhance and optimize the performance of the Datagram Transport Layer Security (DTLS) network for Constrained Application CoAP in Internet of Things. So two mechanisms were designed which lead to the higher performance and the efficiency of the protocol DTLS. Our contribution in this paper is to reduce the cost of communication of the DTLS protocol and improve the...
Many researchers are currently focusing on the security of wireless sensor networks (WSNs). This type of network is associated with vulnerable characteristics such as open-air transmission and self-organizing withoutafixed infrastructure. Intrusion Detection Systems (IDSs) can play an important role in detecting and preventing security attacks. In this paper, we propose a hybrid, lightweight intrusion...
