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.

Die Autorin stellt in diesem Standardwerk die zur Umsetzung der Sicherheitsanforderungen benötigten Verfahren und Protokolle detailliert vor und erläutert sie anschaulich anhand von Fallbeispielen. Im Vordergrund steht dabei, die Ursachen für Probleme heutiger IT-Systeme zu verdeutlichen und die grundlegenden Sicherheitskonzepte mit ihren jeweiligen Vor- und Nachteilen zu präsentieren. Der Leser entwickelt nicht nur ein Bewusstsein für IT-Sicherheitsrisiken, sondern erwirbt auch ein breites und grundlegendes Wissen zu deren Behebung. IT-Systeme und die Digitalisierung sind in allen Bereichen und Branchen von zentraler Bedeutung. Die IT-Sicherheit oder Cybersicherheit nimmt dabei eine tragende Rolle ein. Sie hat die Aufgabe sicher zu stellen, dass die verarbeiteten Daten nicht gezielt verfälscht werden, dass wertvolle Information nicht in falsche Hände gelangt und dass die IT-Systeme nicht in ihrer Funktion beeinträchtigt werden. Heutige IT-Systeme sind einer Vielzahl von Bedrohungen ausgesetzt und weisen noch immer viele Verwundbarkeiten auf. Gleichzeitig gibt es viele, zum Teil standardisierte Sicherheitslösungen, mit denen die Bedrohungen und die damit einhergehenden Risiken reduziert werden können. Kenntnisse möglicher Sicherheitsschwachstellen und möglicher Angriffe auf IT-Systeme, sowie der wichtigsten Sicherheitslösungen und deren Wirksamkeit sind essentiell, um IT-Systeme abzusichern und eine vertrauenswürdige Basis für die digitalen Prozesse zu schaffen. Aus den Inhalten:  Sicherheitsschwachstellen, -bedrohungen und Angriffe  Internet-(Un)Sicherheit  Secure Engineering  Kryptographische Verfahren und Schlüsselmanagement  Digitale Identität  Zugriffskontrolle  Netzwerk-, Kommunikations- und Anwendungssicherheit  Sichere drahtlose Kommunikation Prof. Dr. Claudia Eckert ist Inhaberin des Lehrstuhls Sicherheit in der Informatik der TU München und Direktorin des Fraunhofer-Instituts für Angewandte und Integrierte Sicherheit (AISEC) mit Sitz in Garching bei München.

Thisbookcontainsthepostproceedingsofthe6thEuropeanWorkshoponPublic Key Services, Applications and Infrastructures, which was held at the CNR Research Area in Pisa, Italy, in September 2009. The EuroPKI workshop series focuses on all research and practice aspects of public key infrastructures, services and applications, and welcomes original research papers and excellent survey contributions from academia, government, and industry. Previous events of the series were held in: Samos, Greece (2004); Kent, UK (2005); Turin, Italy, (2006); Palma de Mallorca, Spain, (2007); and Trondheim, Norway (2008). From the original focus on public key infrastructures, EuroPKI interests - panded to include advanced cryptographic techniques, applications and (more generally) services. The Workshops brings together researchersfrom the cryp- graphiccommunity as well as fromthe applied security community, as witnessed by the interesting program. Indeed, this volume holds 18 refereed papers and the presentation paper by the invited speaker, Alexander Dent. In response to the EuroPKI 2009 call for papers, a total of 40 submissions were received. All submissions underwent a thorough blind review by at least three ProgramCommittee members, resulting in careful selection and revision of the accepted papers. After the conference, the papers were revised and improved by the authors before inclusion in this volume.

Rethinking Public Key Infrastructures and Digital Certificates

Building in Privacy

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.
