40、ice Element System Security Object bY name in an abstract 5 General overvrew The Generic Upper Layers Security (GULS) Standards define a set of protocol-construction tools and protocol components to support the provision of security protection for applications. These facilities support the provision

41、 of security services in the OS1 Upper Layers (Application Layer, sometimes with Presentation Layer support). NOTE - Security services for OS1 applications may be provided using security mechanisms at either the upper or lower layers. In the latter case, the protection is obtained by specifying an a

This protection quality-of-service is passed transparently through the Presentation and Session Layers to the transport service. Provision of security servic

The facilities provided in the GULS Standards include: - a general means of building Application Layer protocol components to support the exchange of security- related information between a pair of communica
