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.
