Next Generation SSH2 Implementation
New security risks, continuously evolving regulation and increasing security standards have created new and growing needs for secure internal information transfers, which SSH provides. This book addresses these new trends in depth, offering the most up-to-date information on the integration of SSH into a security environment. It covers the newest features and applications of SSH-2 (which received Proposed Standard status from the IETF in 2006). SSH2 is more secure than previous versions and has many expanded uses on a wider variety of computing platforms. Another particular note driving new SSH2 adoption are the requirements of recent legislation (PCI/HIPAA/SOX/FISMA). SSH 2 has become an even more valuable tool, as it provides communications security compliance with the latest standards.This book offers the most up-to-date information on SSH2 in a practical, hands-on, tutorial-style reference that goes well beyond UNIX implementation. It concentrates on the latest version of SSH 2 with all new information. - Discover why SSH2 offers more robust security than SSH1 and how to incorporate it into your network administration software toolbox
Engineering Secure Devices
This practical guide to building embedded and IoT devices securely is an essential resource for current and future developers tasked with protecting users from the potential threats of these ubiquitous devices. As an engineer, you know that countless devices—from industrial components to smart household appliances—rely on embedded computer systems. But how do you balance the need for robust security with performance and innovative product design? Engineering Secure Devices will guide you through crafting secure devices—from protecting crucial assets to the nature of attackers and the risks they pose. You’ll explore the technical intricacies and pros and cons of symmetric and asymmetric cryptography and learn how to use and analyze random number generators and cryptographic algorithms. You’ll learn how to ensure confidential data storage and secure memory, and devise secure device identity solutions and communication protocols to reinforce system architecture against potential threats. And finally, you’ll learn how to properly design secure boot and secure update processes, manage access control, and perform system monitoring to secure IoT devices. Real-world case studies throughout highlight practical applications, solutions, and obstacles, such as firmware updates with SWUpdate, secure communication with MQTT, and advanced access control with AppArmor. You’ll also dig into topics like: Analyzing the performance of cryptographic implementations in both hardware and software Considerations for secure boot and software update processes to ensure ongoing firmware integrity Designing robust device architectures that withstand attacks while maintaining critical operations Developing strategies to detect and respond to anomalies or security breaches in embedded systems Whether you’re an IoT developer or an embedded system architect, Engineering Secure Devices equips you with the indispensable knowledge to design, secure, and support the next generation of smart devices—from webcams to four-legged robots.
Smart Meters

Release Date: 2023-04-01
This book describes how equipping buildings with smart meters is essential to improve the prediction of energy costs within smart grids and to help end-users optimize their energy consumption. The book reports on the results of the European Upper Rhine INTERREG project SMI (www.smi.uha.fr), which connects artificial intelligence and micro-societal analysis. It is multidisciplinary and addresses the following aspects: social, legal, environmental, and technical. One of the critical factors for the transition to clean energy is the flexibility of the power grid. A flexible grid requires a constant flow of data about the network and its demand, on the other hand, clients who produce electrical power can be an active part of the demand response if they are informed about the power needs of their appliances. “If you cannot measure it, you cannot improve it.” This common management saying also holds true for the area energy efficiency. Without a clear understanding of their energy usage, consumers are unable to take steps to reduce their consumption. A new intelligent tool is presented that is more efficient, safe, and acceptable to consumers. Thus, users of this intelligent tool will be able to collect and predict the consumption of their electrical appliances. At the same time, the consumption information is anonymized before being relayed to the energy supplier. In parallel, new techniques will be evaluated to improve the security level of the smart meter in a highly heterogeneous network.
