The introduction of public key cryptography (PKC) was a critical advance in IT security. In contrast to symmetric key cryptography, it enables confidential communication between entities in open networks, in particular the Internet, without prior contact. Beyond this PKC also enables protection techniques that have no analogue in traditional cryptography, most importantly digital signatures which for example support Internet security by authenticating software downloads and updates. Although PKC does not require the confidential exchange of secret keys, proper management of the private and public keys used in PKC is still of vital importance: the private keys must remain private, and the public keys must be verifiably authentic. So understanding so-called public key infrastructures (PKIs) that manage key pairs is at least as important as studying the ingenious mathematical ideas underlying PKC. In this book the authors explain the most important concepts underlying PKIs and discuss relevant standards, implementations, and applications. The book is structured into chapters on the motivation for PKI, certificates, trust models, private keys, revocation, validity models, certification service providers, certificate policies, certification paths, and practical aspects of PKI. This is a suitable textbook for advanced undergraduate and graduate courses in computer science, mathematics, engineering, and related disciplines, complementing introductory courses on cryptography. The authors assume only basic computer science prerequisites, and they include exercises in all chapters and solutions in an appendix. They also include detailed pointers to relevant standards and implementation guidelines, so the book is also appropriate for self-study and reference by industrial and academic researchers and practitioners.

"Planning for PKI" examines this cornerstone Internet security technology.Written by the architects of the Internet Public Key Infrastructure (PKI),this book provides authoritative technical guidance for network engineers,architects, and managers who need to implement the right PKI architecture for their organization. Readers will learn that building a successful PKI is an on going process, not a one-time event. The authors discuss results and lessons learned from three early PKI deployments, helping readers avoid the pitfalls and emulate the successes of early PKI adopters. Using plain and direct language, the authors share their extensive knowledge of PKI standards development in the Internet Engineering Task Force (IETF) and elsewhere. Subtle points about the Internet PKI standards are liberally sprinkled throughout the book. These nuggets provide insight into the intent of some of the esoteric topics in the standards, enabling greater interoperability. "Planning for PKI" gathers the PKI state-of-the-art into one volume, covering everything from PKI history to emerging PKI-related technologies.

As paper-based communication and transaction mechanisms are replaced by automated ones, traditional forms of security such as photographs and handwritten signatures are becoming outdated. Most security experts believe that digital certificates offer the best technology for safeguarding electronic communications. They are already widely used for authenticating and encrypting email and software, and eventually will be built into any device or piece of software that must be able to communicate securely. There is a serious problem, however, with this unavoidable trend: unless drastic measures are taken, everyone will be forced to communicate via what will be the most pervasive electronic surveillance tool ever built. There will also be abundant opportunity for misuse of digital certificates by hackers, unscrupulous employees, government agencies, financial institutions, insurance companies, and so on.In this book Stefan Brands proposes cryptographic building blocks for the design of digital certificates that preserve privacy without sacrificing security. Such certificates function in much the same way as cinema tickets or subway tokens: anyone can establish their validity and the data they specify, but no more than that. Furthermore, different actions by the same person cannot be linked. Certificate holders have control over what information is disclosed, and to whom. Subsets of the proposed cryptographic building blocks can be used in combination, allowing a cookbook approach to the design of public key infrastructures. Potential applications include electronic cash, electronic postage, digital rights management, pseudonyms for online chat rooms, health care information storage, electronic voting, and even electronic gambling.

Most books on public key infrastructure (PKI) seem to focus on asymmetric cryptography, X.509 certificates, certificate authority (CA) hierarchies, or certificate policy (CP), and certificate practice statements. While algorithms, certificates, and theoretical policy are all excellent discussions, the real-world issues for operating a commercial or private CA can be overwhelming. Security without Obscurity: A Guide to PKI Operations provides a no-nonsense approach and realistic guide to operating a PKI system. In addition to discussions on PKI best practices, the book supplies warnings against bad PKI practices. Scattered throughout the book are anonymous case studies identifying both good and bad practices. The highlighted bad practices, based on real-world scenarios from the authors’ experiences, illustrate how bad things are often done with good intentions but cause bigger problems than the original one being solved. This book offers readers the opportunity to benefit from the authors’ more than 50 years of combined experience in developing PKI-related policies, standards, practices, procedures, and audits, as well as designing and operating various commercial and private PKI systems.

The only complete guide to designing, implementing, and supporting state-of-the-art certificate-based identity solutions with PKI Layered approach is designed to help readers with widely diverse backgrounds quickly learn what they need to know Covers the entire PKI project lifecycle, making complex PKI architectures simple to understand and deploy Brings together theory and practice, including on-the-ground implementers' knowledge, insights, best practices, design choices, and troubleshooting details PKI Uncovered brings together all the techniques IT and security professionals need to apply PKI in any environment, no matter how complex or sophisticated. At the same time, it will help them gain a deep understanding of the foundations of certificate-based identity management. Its layered and modular approach helps readers quickly get the information they need to efficiently plan, design, deploy, manage, or troubleshoot any PKI environment. The authors begin by presenting the foundations of PKI, giving readers the theoretical background they need to understand its mechanisms. Next, they move to high-level design considerations, guiding readers in making the choices most suitable for their own environments. The authors share best practices and experiences drawn from production customer deployments of all types. They organize a series of design "modules" into hierarchical models which are then applied to comprehensive solutions. Readers will be introduced to the use of PKI in multiple environments, including Cisco router-based DMVPN, ASA, and 802.1X. The authors also cover recent innovations such as Cisco GET VPN. Throughout, troubleshooting sections help ensure smooth deployments and give readers an even deeper "under-the-hood" understanding of their implementations.
