Introduction The present document is part of a TS-family covering the 3rdGeneration Partnership Project; Technical Specification Group Services and System Aspects; Telecommunication management; as identified below: 32.371: “Se
19、curity Management concept and requirements“. 32.372: “Security Services for Integration Reference Points (IRP): Information Service (IS)“. 32.373: “Security Services for Integration Reference Points (IRP): Common Object Request Broker Architecture (CORBA) solution“. 32.375 “Security Services for Int
20、egration Reference Points (IRP): File integrity solution“. In 3GPP SA5 context, IRPs are introduced to address process interfaces at the Itf-N interface. The Itf-N interface is built up by a number of IRPs and a related Name Convention, which realize the functional capabilities over this interface.
21、The basic structure of the IRPs is defined in 3GPP TS 32.101 1 and 3GPP TS 32.102 2. An IRP consists of IRPManager and IRPAgent. Usually there are three types of transaction between IRPManager and IRPAgent, which are: operation invocation, notification, and file transfer. However, there are differen
22、t types of intentional threats against the transaction between IRPManagers and IRPAgents. All the threats are potential risks of damage or degradation of telecommunication services, which operators should take measures to reduce or eliminate to secure the telecommunication service, network, and data
23、. The present document is applicable to the Interface IRP specifications. That is to say, it is only concerned with the security aspects of operations/notifications/file deployed across the Itf-N. The present document introduces XML Signature mechanism to address File Integrity security requirement

32、.372 5. This clause specifies features that are specific to the File integrity solution. 4.1 Principles of IRP Security Services Figure 4.1 shows that Security Services are between IRP Application layer and Transport layer. Security Attributes which are attached to network management information are
33、 transferred between IRPManager and IRPAgent to address Authentication, Authorization, Activity Log and file integrity requirements. IRPManager ApplicationSecurity ServicesTransport layerIRPAgent ApplicationSecurity ServicesTransport layernetwork managementinformationattached Security AttributesFigu
34、re 4.1 : Principles of IRP Security Service The basic idea of these Security Services is as follows: IRP Security Services on IRPManager side and IRP Security Services on IRPAgent side co-operate to provide Security Services for IRP. This avoids modifying IRPManager and IRPAgent much. When the IRPMa
35、nager and/or IRPAgent send network management information to each other, the IRP Security Service (on IRPManager and/or IRPAgent side) attaches Security Attributes to the network management information. The receiver works with the attached Security Attributes to implement the IRP security requiremen
36、t. The present document addresses File integrity solution by using the XML Signature Mechanism defined by 9. Table 4.1 identifies the use of File Integrity solution to realize File Integrity Security Service. Table 4.1 : File Integrity solution and Security Service relationship Authentication Securi

38、n 9.0.0 Release 94.2 XML Signature Recommendation This clause introduces the concept of XML Signature detailed in 9. It is used to transfer XML Signature over Itf-N to provide the File Integrity Security Service. Based on 9, data to be signed is canonicalized by using a specific method, i.e. using a
39、 unique form to represent XML files with the same semantic content but different text. The canonicalized data may be transformed before it is digested by using a specific method. The digest value is encrypted by using a specific signature method. The key information used to verify the signed value o
40、f signed data may be included in the XML Signature. As shown in 9, XML digital signatures are represented by the Signature element which has the following structure (where “?“ denotes zero or one occurrence; “+“ denotes one or more occurrences; and “*“ denotes zero or more occurrences): ( ()? )+ ()?
41、 ()* 5 Mapping 5.1 File Integrity Solution Mapping 5.1.1 Security Attribute Mapping In File Integrity Solution scenario, XML Signature as Security Attributes is exchanged over Itf-N accompanying the file(s) to be transferred.

ETSI ETSI TS 132 375 V9.0.0 (2010-02)83GPP TS 32.375 version 9.0.0 Release 96 Itf-N Security Service Behaviour This clause describes some
43、 behaviour of IRPManager and IRPAgent not captured by XML Schema in File Integrity Solution. 6.1 File Integrity Solution This clause addresses how to use XML Signature to provide File Integrity Security Service. To Enable IRPManager and IRPAgent to use XML Signature, these two sides should agree wit
44、h Canonicalization Method, Transform Method, Digest Method, and Signature Method before they start communication. Mandatory methods defined in 9 should be supported by IRPManager and IRPAgent. When an XML document instance is to be exchanged over Itf-N, the sender should make sure the whole XML docu
45、ment instance should be signed. The corresponding XML Signature should be held in the XML document instance. When an XML document instance is received, the receiver should verify the XML document instance by using the process defined in 9. If the verification is successful, receiver works with the X
46、ML document instance as normal; otherwise receiver should raise a security alarm if it is IRPAgent or process the failure in a vendor specific way if it is IRPManager.
