3.2.2.4.1.3 Find or Create a Security Context

The client SHOULD use the activity's current security context, represented by the activity's security context handle, unless the context has expired. <82>If the client chooses to create a new security context for any reason, then it will set the activity's current security context handle equal to the handle value for the new security context created. See section 3.2.1.4.1.1 for information on creating a security context. Each security context MUST have a unique Context Identifier (transmitted as key_vers_num), which is specified in the sec_trailer structure, to allow the server to identify which security context is used for a given PDU.
