26、have been incorporated in the document. Introduction An identified security weakness in 2G 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
27、longer the case, and so there is now a need for security precautions. Another significant development 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 use
28、r traffic. The introduction of IP therefore signifies not only a shift towards packet switching, 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 an
29、d risks must be faced. For 3G and fixed broadband systems it is a clear goal to be able to 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
30、 for IP related security in the 3GPP and fixed broadband core networks. The security services 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 ETS
31、I TS 133 210 V13.0.0 (2016-01)63GPP TS 33.210 version 13.0.0 Release 131 Scope The present 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 pl
32、ane security is to cover the control signalling on selected interfaces between network elements of NDS/IP networks. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

Anti-replay protection: Anti-replay protection is a special
47、case of integrity protection. Its main service is to protect against replay of self-contained packets that already have a cryptographical integrity mechanism in place. Confidentiality: The property that information is not made available or disclosed to unauthorised individuals, entities or processes
48、. Data integrity: The property that data has not been altered in an unauthorised manner. Data origin authentication: The corroboration that the source of data received is as claimed. Entity authentication: The provision of assurance of the claimed identity of an entity. Key freshness: A key is fresh
49、 if it can be guaranteed to be new, as opposed to an old key being reused through actions of either an adversary or authorised party. NDS/IP Traffic: Traffic that requires protection according to the mechanisms defined in this specification.
