Should the TSG modify the 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
25、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 document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates,
26、etc. z the third digit is incremented when editorial only changes 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
27、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 development has been the introduction of IP as the network layer in the GPRS backbone network and then later in the UMTS network domain. Further
28、more, 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 switching, which is a major change by its own accounts, but also a shift towards completely open and easily accessible protocols. The implication is
29、 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 protect the core network signalling protocols, and by implication this means that security solutions must be found for both SS7 and IP based pr
30、otocols. This technical specification is the stage-2 specification 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 b
31、y standard procedures, based on cryptographic techniques. ETSI ETSI TS 133 210 V14.0.0 (2017-05)63GPP TS 33.210 version 14.0.0 Release 141 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
32、 fixed broadband networks). The scope of network domain control plane 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 o

46、 the present document, the following terms and definitions apply. Anti-replay protection: Anti-replay protection is a special 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. Confid
47、entiality: The property that information is not made available or disclosed to unauthorised individuals, entities or processes. 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
48、claimed. Entity authentication: The provision of assurance of the claimed identity of an entity. Key freshness: A key is fresh 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 pr
49、otection according to the mechanisms defined in this specification. NDS/IP-networks: 3GPP and fixed broadband networks.
