This book was released on 2020 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document constitutes a preparation toward devising criteria for the standardization of threshold schemes for cryptographic primitives by the National Institute of Standards and Technology (NIST). The large diversity of possible threshold schemes, as identified in the NIST Internal Report (NISTIR) 8214, is structured along two main tracks: single-device and multi-party. Each track covers cryptographic primitives in several possible threshold modes. The potential for real-world applications is taken as an important motivating factor for differentiating the pertinence of each possible threshold scheme. Also, the selection of items for standardization needs to consider diverse features, such as advanced security properties, configurability of parameters, testing and validation, modularity and composability (e.g., of gadgets vs. composites), and specification detail. Overall, the organization put forward serves as a preparation for an upcoming solicitation of feedback useful for considering a variety of threshold schemes, while differentiating standardization paths and timelines that may depend on the levels of technical and standardization challenges. This approach paves the way for an effective engagement with the community of stakeholders and constitutes a preparation for devising criteria for standardization and subsequent calls for contributions. While the terms standards and standardization are used throughout this report to refer to a set of possible final products, this does not imply a Federal Information Processing Standard (FIPS) as one or as the only intended format for NIST products of future threshold schemes for cryptographic primitives.

Available in PDF, EPUB and Kindle. Book excerpt: The Computer Security Division at the National Institute of Standards and Technology is interested in promoting the security of implementations of cryptographic primitives. This security depends not only on the theoretical properties of the primitives but also on the ability to withstand attacks on their implementations. It is thus important to mitigate breakdowns that result from differences between ideal and real implementations of cryptographic algorithms. This document overviews the possibility of implementing cryptographic primitives using threshold schemes, where multiple components contribute to the operation in a way that attains the desired security goals even if f out of n of its components are compromised. There is also an identified potential in providing resistance against side-channel attacks, which exploit inadvertent leakage from real implementations. Security goals of interest include the secrecy of cryptographic keys, as well as enhanced integrity and availability, among others. This document considers challenges and opportunities related to standardization of threshold schemes for cryptographic primitives. It includes examples illustrating security tradeoffs under variations of system model and adversaries. It enumerates several high-level characterizing features of threshold schemes, including the types of threshold, the communication interfaces (with the environment and between components), the executing platform (e.g., single device vs. multiple devices) and the setup and maintenance requirements. The document poses a number of questions, motivating aspects to take into account when considering standardization. A particular challenge is the development of criteria that may help guide a selection of threshold cryptographic schemes. An open question is deciding at what level each standard should be defined (e.g., specific base techniques vs. conceptualized functionalities) and which flexibility of parametrization they should allow. Suitability to testing and validation of implementations are also major concerns to be addressed. Overall, the document intends to support discussion about standardization, including motivating an engagement from stakeholders. This is a step towards enabling threshold cryptography within the US federal government and beyond.

This book was released on 2018-07-26 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: NISTIR 8214 Released 1 March 2019 As cryptography becomes ubiquitous, it becomes increasingly relevant to address the potentially disastrous breakdowns resulting from differences between ideal and real implementations of cryptographic algorithms. These differences give rise to a range of attacks that exploit vulnerabilities in order to compromise diverse aspects of real-world implementations. Threshold schemes have the potential to enable secure modes of operation even when certain subsets of components are compromised. However, they also present new challenges for the standardization and validation of security assertions about their implementations. Why buy a book you can download for free?

Available in PDF, EPUB and Kindle. Book excerpt: The superabundance of data that is created by today's businesses is making storage a strategic investment priority for companies of all sizes. As storage takes precedence, the following major initiatives emerge: Flatten and converge your network: IBM® takes an open, standards-based approach to implement the latest advances in the flat, converged data center network designs of today. IBM Storage solutions enable clients to deploy a high-speed, low-latency Unified Fabric Architecture. Optimize and automate virtualization: Advanced virtualization awareness reduces the cost and complexity of deploying physical and virtual data center infrastructure. Simplify management: IBM data center networks are easy to deploy, maintain, scale, and virtualize, delivering the foundation of consolidated operations for dynamic infrastructure management. Storage is no longer an afterthought. Too much is at stake. Companies are searching for more ways to efficiently manage expanding volumes of data, and to make that data accessible throughout the enterprise. This demand is propelling the move of storage into the network. Also, the increasing complexity of managing large numbers of storage devices and vast amounts of data is driving greater business value into software and services. With current estimates of the amount of data to be managed and made available increasing at 60% each year, this outlook is where a storage area network (SAN) enters the arena. SANs are the leading storage infrastructure for the global economy of today. SANs offer simplified storage management, scalability, flexibility, and availability; and improved data access, movement, and backup. Welcome to the cognitive era. The smarter data center with the improved economics of IT can be achieved by connecting servers and storage with a high-speed and intelligent network fabric. A smarter data center that hosts IBM Storage solutions can provide an environment that is smarter, faster, greener, open, and easy to manage. This IBM® Redbooks® publication provides an introduction to SAN and Ethernet networking, and how these networks help to achieve a smarter data center. This book is intended for people who are not very familiar with IT, or who are just starting out in the IT world.

Available in PDF, EPUB and Kindle. Book excerpt: Most innovations in the car industry are based on software and electronics, and IT will soon constitute the major production cost factor. It seems almost certain that embedded IT security will be crucial for the next generation of applications. Yet whereas software safety has become a relatively well-established field, the protection of automotive IT systems against manipulation or intrusion has only recently started to emerge. Lemke, Paar, and Wolf collect in this volume a state-of-the-art overview on all aspects relevant for IT security in automotive applications. After an introductory chapter written by the editors themselves, the contributions from experienced experts of different disciplines are structured into three parts. "Security in the Automotive Domain" describes applications for which IT security is crucial, like immobilizers, tachographs, and software updates. "Embedded Security Technologies" details security technologies relevant for automotive applications, e.g., symmetric and asymmetric cryptography, and wireless security. "Business Aspects of IT Systems in Cars" shows the need for embedded security in novel applications like location-based navigation systems and personalization. The first book in this area of fast-growing economic and scientific importance, it is indispensable for both researchers in software or embedded security and professionals in the automotive industry.
