1 Introduction
The Online Certificate Status Protocol (OCSP) Extensions provide the Microsoft implementation of the Lightweight Online Certificate Status Protocol (OCSP) Profile for High Volume Environments [RFC5019], a profile of the Online Certificate Status Protocol (OCSP) [RFC2560] and any extensions to [RFC5019]. Within this document, the term "this protocol" refers to the Online Certificate Status Protocol (OCSP) Extensions.
Familiarity with public key infrastructure (PKI) concepts such as asymmetric and symmetric cryptography, asymmetric and symmetric encryption techniques, digital certificate concepts, and cryptographic key establishment is required for a complete understanding of this protocol. [CRYPTO] provides an excellent introduction to cryptography and PKI concepts. [X509] provides an excellent introduction to PKI and certificate concepts.
