Abstract

The present document defines an electronic interface for the exchange of information relating to the establishment and management of Lawful Interception. Typically, this interface would be used between a central LI administration function and the network internal interception points.  Typical reference models for LI define an interface between Law Enforcement Agencies (LEAs) and Communication Service Providers (CSPs), called the handover interface. They also define an internal network interface within the CSP domain between administration and mediation functions for lawful interception and network internal functions, which facilitates the interception of communication. This internal network interface typically consists of sub-interfaces; initial configuration of the network internal elements of lawful interception (X0), administration (called X1), transmission of intercept related information (X2), transmission of content of communication (X3).  The present document specifies the X0 interface for configuration of the network elements of lawful interception.  It also covers the needs of the virtualized environments and specifies the initial trust establishment of the LI interfaces to secure that LI functions get identities (certificates) for LI only after being verified (e.g. using attestation) and endorsed for LI use.  The present document is tightly related to the ETSI Lawful Interception Architecture, ETSI TS 104 007 [2]. ETSI TS 104 007 [2] describes the architecture for the LI system and the new X0 interface used for building trust and setup of the X1/2/3 interfaces, the present document specifies the role and detailed definition of interface X0 and how it couples with interfaces X1/2/3. The present document and ETSI TS 104 007 [2] plug together and give a complete model of the LI system.  X0 is characterized in standard documents ETSI GR NFV SEC-011 [i.1] and 3GPP TS 33.127 [i.3] through descriptions and requirements.
