Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document is part 6 of a multi-part deliverable covering Satellite Earth Stations and Sy

19、stems (SES); Satellite Component of UMTS/IMT-2000; Multimedia Broadcast/Multicast Services, as identified below: Part 1: “Services definitions“; Part 2: “Architecture and functional description“; Part 3: “Introduction in the Radio Access Network (RAN)“; Part 4: “Interworking with terrestrial UMTS ne

20、tworks“; Part 5: “Performances over the radio interface“; Part 6: “Security“. Introduction S-UMTS stands for the Satellite component of the Universal Mobile Telecommunication System. S-UMTS systems will complement the terrestrial UMTS (T-UMTS) and inter-work with other IMT-2000 family members throug

21、h the UMTS core network. S-UMTS will be used to deliver 3rdgeneration mobile satellite services (MSS) utilizing either low (LEO) or medium (MEO) earth orbiting, or geostationary (GEO) satellite(s). S-UMTS systems are based on terrestrial 3GPP specifications and will support access to GSM/UMTS core n

22、etworks. NOTE 1: The term T-UMTS will be used in the present document to further differentiate the Terrestrial UMTS component. Due to the differences between terrestrial and satellite channel characteristics, some modifications to the terrestrial UMTS (T-UMTS) standards are necessary. Some specifica

23、tions are directly applicable, whereas others are applicable with modifications. Similarly, some T-UMTS specifications do not apply, whilst some S-UMTS specifications have no corresponding T-UMTS specification. Since S-UMTS is derived from T-UMTS, the organization of the S-UMTS specifications closel

24、y follows the original 3rdGeneration Partnership Project (3GPP) structure. An S-UMTS system is defined by the combination of a family of S-UMTS specifications and 3GPP specifications, as follows: If an S-UMTS specification exists it takes precedence over the corresponding 3GPP specification (if any)

25、. This precedence rule applies to any references in the corresponding 3GPP specifications. ETSI ETSI TS 102 442-6 V1.1.1 (2006-11) 6 NOTE 2: Any references to 3GPP specifications within the S-UMTS specifications are not subject to this precedence rule. For example, an S-UMTS specification may contai

26、n specific references to the corresponding 3GPP specification. If an S-UMTS specification does not exist, the corresponding 3GPP specification may or may not apply. The exact applicability of the complete list of 3GPP specifications shall be defined at a later stage. ETSI ETSI TS 102 442-6 V1.1.1 (2

33、ements of 1 shall apply. Adaptations for the case BM-SC located outside the mobile operator. 4.2 General security requirements 4.2.1 Service level security 4.2.1.1 Secure access to S-MBMS services It shall be possible to prevent intruders, including relay nodes, from obtaining unauthorized access to

34、 S-MBMS services by masquerading as authorized users. It shall be possible to prevent intruders, including relay nodes, from hijacking a service already provided to a user. It shall not be possible for unjustified charges to be imposed on users. It shall be possible for users to be able to verify th

35、at serving networks are authorized to offer S-MBMS service on behalf of the users Home Environment at the start of, and during, service delivery. It shall not be possible for simultaneous access to S-MBMS services by multiple users from the same terminal to jeopardize the security of individual acce

36、ss to S-MBMS service. It shall be possible to protect against unauthorized modification of multicast, signalling and control data, particularly on radio interfaces. It shall be possible to protect the confidentiality of multicast, signalling and control data, particularly on radio interfaces. 4.2.1.

37、2 Protection of user-related transmitted data It shall be possible to protect the confidentiality of user traffic, particularly on radio interfaces, including protection against eavesdropping from relay nodes. It shall be possible to protect the confidentiality of user identity data, particularly on

38、 radio interfaces, including protection against eavesdropping from relay nodes. It shall be possible to protect the confidentiality of location data about users, particularly on radio interfaces, including protection against eavesdropping from relay nodes. It shall be possible to protect against the

39、 unauthorized disclosure of location data about users participating in a particular S-MBMS service to other parties participating in the same S-MBMS service. It shall be possible to protect against unauthorized modification of user traffic. It shall be possible for the user to be able to check wheth

40、er or not his user traffic is protected, particularly on radio interfaces. 4.2.1.3 Protection of user-related stored data It shall be possible to protect against unauthorized modification of user-related data which is stored or processed by a provider. It shall be possible to protect the confidentia

41、lity of user-related data which is stored or processed by a provider. ETSI ETSI TS 102 442-6 V1.1.1 (2006-11) 9 It shall be possible to protect against unauthorized modification of user-related data stored in the terminal or in the USIM. It shall be possible to protect the confidentiality of user-re

42、lated data stored in the terminal or in the USIM. 4.2.2 Provider security requirements 4.2.2.1 USIM security A valid USIM shall be required to access any S-MBMS service except for emergency broadcast messages where the network should be allowed to decide whether or not emergency calls should be perm

43、itted without a USIM. It shall be possible to prevent the use of a particular USIM to access S-MBMS services. It shall be possible to control access to a USIM so that it can only be used to access S-MBMS services by the subscriber to whom it was issued or by users explicitly authorized by that subsc

44、riber. It shall be possible to control access to data in a USIM. For instance, some data may only be accessible by an authorized home environment. It shall not be possible to access data in a USIM that is only intended to be used within the USIM, e.g. authentication keys and algorithms. If a UICC co

45、ntains more than one USIM (to access services from different home environments) then different home environments shall only have access to the USIMs of their own users. If a UICC contains more than one USIM (to access services from different home environments) then security management data (e.g. aut

46、hentication information) of each USIM shall be protected independently against unauthorized access and modification. It shall be possible to control access to, and selection of, USIMs and other non-S-MBMS applications stored on the same UICC. In particular, it shall be possible to have shared direct

47、ories between applications where appropriate. It shall be possible to ensure that the origin and integrity of applications and/or data downloaded to the UICC can be checked. It may also be necessary to ensure that the confidentiality of downloaded applications and/or data can be ensured. 4.2.2.2 Sec

48、ure provision of S-MBMS services It shall be possible for providers to authenticate users at the start of, and during, service delivery to prevent intruders (including relay nodes) from obtaining unauthorized access to S-MBMS services by masquerade or misuse of priorities. It shall be possible to de

49、tect and prevent the fraudulent use of services. Alarms will typically need to be raised to alert providers to security-related events. Audit logs of security related events will also need to be produced. It shall be possible for a home environment to cause an immediate termination of all services provided to users associated with that home environment. It shall be possible for the serving network to be able to authenticate the origin of user traffic, signaling data and control data on radio interfaces. It shall be possible to prevent intruders from res
