Applied Public Key Infrastructure

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.

Includes topics such as: Public Key Infrastructure (PKI) Operation and Case Study, Non-repudiation, Authorization and Access Control, Authentication and Time-Stamping, Certificate Validation and Revocation, and Cryptographic Applications.

With the recent Electronic Signatures in Global and National Commerce Act, public key cryptography, digital signatures, and digital certificates are finally emerging as a ubiquitous part of the Information Technology landscape. Although these technologies have been around for over twenty years, this legislative move will surely boost e-commerce act

Written by the experts at RSA Security, this book will show you how to secure transactions and develop customer trust in e-commerce through the use of PKI technology. Part of the RSA Press Series.

PKI (public-key infrastructure) enables the secure exchange of data over otherwise unsecured media, such as the Internet. PKI is the underlying cryptographic security mechanism for digital certificates and certificate directories, which are used to authenticate a message sender. Because PKI is the standard for authenticating commercial electronic transactions,Understanding PKI, Second Edition, provides network and security architects with the tools they need to grasp each phase of the key/certificate life cycle, including generation, publication, deployment, and recovery.

This book constitutes the refereed proceedings of the 4th European Symposium on Research in Computer Security, ESORICS '96, held in Rome, Italy, in September 1996 in conjunction with the 1996 Italian National Computer Conference, AICA '96. The 21 revised full papers presented in the book were carefully selected from 58 submissions. They are organized in sections on electronic commerce, advanced access control models for database systems, distributed systems, security issues for mobile computing, network security, theoretical foundations of security, and secure database architectures.

This book constitutes the refereed proceedings of the Third European Public Key Infrastructure Workshop: Theory and Practice, EuroPKI 2006, held in Torino, Italy, in June 2006. The 18 revised full papers and 4 short papers presented were carefully reviewed and selected from about 50 submissions. The papers are organized in topical sections on PKI management, authentication, cryptography, applications, and short contributions.
