Abstract

This Generic Security Service Application Program Interface (GSS-API) definition provides security services to callers in a generic fashion, supportable with a range of underlying mechanisms and technologies and hence allowing source-level portability of applications to different environments. This specification defines GSS-API services and primitives at a level independent of underlying mechanism and programming language environment, and is to be complemented by other, related specifications:

Abstract

This Generic Security Service Application Program Interface (GSS-API)

definition provides security services to callers in a generic

fashion, supportable with a range of underlying mechanisms and

technologies and hence allowing source-level portability of

applications to different environments. This specification defines

GSS-API services and primitives at a level independent of underlying

mechanism and programming language environment, and is to be

complemented by other, related specifications:

documents defining specific parameter bindings for particular

language environments

documents defining token formats, protocols, and procedures to

be implemented in order to realize GSS-API services atop

particular security mechanisms
