Introductio
26、n The TISPAN NGN R3 security is defined by the security requirements in the present document, while the architectural aspects and stage 2 implementations outline are covered in the Security Architecture for R3 (TS 187 003 1). ETSI ETSI TS 187 001 V3.9.1 (2014-07) 61 Scope The present document define
27、s the security requirements pertaining to TISPAN NGN Release 3. The present document holds requirements for the various NGN subsystems defined at a stage 1 level. The present document covers security requirements for both the NGN core network, and the NGN access network(s). The main scope of the sec
28、urity requirements for the different subsystems are to identify requirements in the following main areas: Security Policies. Authentication, Authorization, Access Control and Accountability. Identity and Secure Registration. Communications and Data Security Requirements (including confidentiality, i
29、ntegrity aspects). Privacy. Key Management. NAT/Firewall Interworking. Availability and DoS protection. Assurance. Strength of Security Mechanisms. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific re

42、originating user trusted channel: means by which an NGN and a remote NGN/NGCN can communicate with necessary confidence to support the security policies of the NGN (from ISO 15408-1 i.1) ETSI ETSI TS 187 001 V3.9.1 (2014-07) 8trusted domain: in the context of one or more NGNs interconnected by the N

Users shall be able to reject communications that do not conform to their minimum secur
45、ity policy. (R-SP- 3) The security mechanisms shall be partitioned such that the functions of authentication, data integrity, replay detection, and confidentiality may be implemented and selected independently of each other, insofar as this makes sense. (R-SP- 4) The UE shall always offer encryption
46、 algorithms for P-CSCF to be used for the session and the P-CSCF policy shall define whether to use encryption or not. (R-SP- 5) The UE and the P CSCF shall negotiate the integrity algorithm that shall be used for the session. (R-SP- 6) The policy of the HN shall be used to decide if an authenticati
47、on shall take place for the registration of different IMPUs e.g. belonging to same or different service profiles. (R-SP- 7) The security gateway functions (SEGF) shall be responsible for enforcing security policies for the interworking between networks. NOTE: The actual inter-security domain policy
48、is not standardized and is left to the discretion of the roaming agreements of the operators. (R-SP- 8) SEGFs are responsible for security sensitive operations and shall offer capabilities for secure storage of long-term keys used for IKE authentication. 4.2 Authentication, Authorization, Access Con
