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. The basic structure of the IRPs is defined in 3GPP TS 32.101  and 3GPP TS 32.102 .
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 different 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.
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 defined in 3GPP TS 32.371 .
