3.2 Relation to X.509 Architecture

3.2 Relation to X.509 Architecture

CCITT 1988 Recommendation X.509, "The Directory - Authentication Framework", defines a framework for authentication of entities involved in a distributed directory service. Strong authentication, as defined in X.509, is accomplished with the use of public-key cryptosystems. Unforgeable certificates are generated by certification authorities; these authorities may be organized hierarchically, though such organization is not required by X.509. There is no implied mapping between a certification hierarchy and the naming hierarchy imposed by directory system naming attributes.

This document interprets the X.509 certificate mechanism to serve the needs of PEM in the Internet environment. The certification hierarchy proposed in this document in support of privacy enhanced mail is intentionally a subset of that allowed under X.509. This certification hierarchy also embodies semantics which are not explicitly addressed by X.509, but which are consistent with X.509 precepts. An overview of the rationale for these semantics is provided in Section 1.
