25、TS 33.210 version 15.0.0 Release 15Foreword 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 conte
26、nts 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 approved doc
27、ument 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 An identified security weakness in 2G
28、systems is the absence of security in the core network. This was formerly perceived not to be a problem, since the 2G networks previously were the provinces of a small number of large institutions. This is no longer the case, and so there is now a need for security precautions. Another significant d
29、evelopment has been the introduction of IP as the network layer in the GPRS backbone network and then later in the UMTS network domain. Furthermore, IP is not only used for signalling traffic, but also for user traffic. The introduction of IP therefore signifies not only a shift towards packet switc
30、hing, which is a major change by its own accounts, but also a shift towards completely open and easily accessible protocols. The implication is that from a security point of view, a whole new set of threats and risks must be faced. For 3G and fixed broadband systems it is a clear goal to be able to
31、protect the core network signalling protocols, and by implication this means that security solutions must be found for both SS7 and IP based protocols. This technical specification is the stage-2 specification for IP related security in the 3GPP and fixed broadband core networks. The security servic
32、es that have been identified as being needed are confidentiality, integrity, authentication and anti-replay protection. These will be ensured by standard procedures, based on cryptographic techniques. ETSI ETSI TS 133 210 V15.0.0 (2018-07)63GPP TS 33.210 version 15.0.0 Release 151 Scope The present
33、document defines the security architecture for network domain IP based control planes, which shall be applied to NDS/IP-networks (i.e. 3GPP and fixed broadband networks). The scope of network domain control plane security is to cover the control signalling on selected interfaces between network elem
34、ents of NDS/IP networks. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a s
