34、3GPP TS 33.310 version 13.2.0 Release 13Foreword This Technical Specification has been produced by the 3rdGeneration Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the
35、contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approve
36、d document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction For 3GPP systems there is a need
37、for truly scalable entity Authentication Framework (AF) since an increasing number of network elements and interfaces are covered by security mechanisms. This specification provides a highly scalable entity authentication framework for 3GPP network nodes. This framework is developed in the context o
38、f the Network Domain Security work item, which effectively limits the scope to the control plane entities of the core network. Thus, the Authentication Framework will provide entity authentication for the nodes that are using NDS/IP. Feasible trust models (i.e. how CAs are organized) and their effec
39、ts are provided. Additionally, requirements are presented for the used protocols and certificate profiles, to make it possible for operator IPsec and PKI implementations to interoperate. ETSI ETSI TS 133 310 V13.2.0 (2017-01)73GPP TS 33.310 version 13.2.0 Release 131 Scope The scope of this Technica
40、l Specification is limited to authentication of network elements, which are using NDS/IP or TLS, and to Certificate Enrolment for Base Stations as described in the present document. In the case of NDS/IP this specification includes both the authentication of Security Gateways (SEG) at the correspond
41、ing Za-interfaces and the authentication between NEs and between NEs and SEGs at the Zb-interface. Authentication of end entities (i.e. NEs and SEGs) in the intra-operator domain is considered an internal issue for operators. This is quite much in line with 1 which states that only Za is mandatory a
42、nd that the security domain operator can decide if the Zb-interface is deployed or not, as the Zb-interface is optional for implementation. Validity of certificates may be restricted to the operators domain in case of Zb interface or in case of Za-interface between two security domains of the same o
43、perator. NOTE: In case two SEGs interconnect separate network regions under a single administrative authority (e.g. owned by the same mobile operator) then the Za-interface is not subject to interconnect agreements, but the decision on applying Za-interface is left to operators. The NDS architecture
44、 for IP-based protocols is illustrated in figure 1. ZaZbZbZbSEGASecurity Domain A Security Domain BSEGBNEA-1NEA-2ZbZbZbNEB-1NEB-2IKE “connection“ESP tunnelFigure 1: NDS architecture for IP-based protocols 1 In the case of TLS this Specification concentrates on authentication of TLS entities across i
45、nter-operator links. For example, TLS is specified for inter-operator communications between IMS and non-IMS networks TS 33.203 9 and on the Zn interface in GBA TS 33.220 10. Authentication of TLS entities across intra-operator links is considered an internal issue for operators. However, NDS/AF can
46、 easily be adapted to the intra-operator use case since it is just a simplification of the inter-operator case when all TLS NEs and the PKI infrastructure belong to the same operator. Validity of certificates may be restricted to the operators domain. An Annex contains information on the manual hand
47、ling of TLS certificates in case automatic enrolment and revocation according to NDS/AF for TLS is not implemented. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identifi
