Annex 1 to the Ordinance of the of the Federal Department of Justice and Police (FDJP) of 15 November 2017 on the conduct of the Surveillance of Post and Telecommunications (VD- ÜPF; SR 780.11.XX) Technical requirements for the handover interfaces for the conduct of the Surveillance of Telecommunications Version 1 Entry into force: 1 March 2018 Technical requirements for the handover interfaces for the execution of telecommunications surveillance 1 Scope of application The present document is the Annex 1 to the ordinance of the FDJP of 15 November 2017 on the conduct of the surveillance of post and telecommunications (VD-ÜPF). It defines the technical requirements and options for the handover interfaces between the equipment of the Communication Service Providers (CSPs) and the equipment of the Post and Telecommunications Surveillance Service (PTSS) for the provision of information requests, real-time interceptions, retroactive interceptions (historical data), emergency searches and tracing. It specifies how the respective ETSI technical specifications apply to the different administrative and technical handover interfaces in Switzerland. Some of the administrative and technical handover interfaces are not standardised by ETSI and are therefore specified in a proprietary manner in this document. 2 Technical requirements for the handover interfaces for the execution of telecommunications surveillance Contents 1 Scope of application .....................................................................................................2 2 Abbreviations ................................................................................................................4 3 Definitions......................................................................................................................7 4 Administrative Handover Interfaces ............................................................................8 4.1 General ....................................................................................................................8 4.2 XML over HTTP Exchange .......................................................................................9 4.3 Secure Email Exchange .........................................................................................45 4.4 Telephone and fax..................................................................................................66 4.5 Registered mail ......................................................................................................67 5 Target Identifiers .........................................................................................................68 6 Real-time Surveillance (Lawful Interception).............................................................69 6.1 General ..................................................................................................................69 6.2 Real-time interception types ...................................................................................69 6.3 Common identifiers and parameters of the handover interfaces .............................70 6.4 ASN.1 parameters definition ...................................................................................78 6.5 Handover interfaces requirements and options ......................................................78 6.6 Applicable ASN.1 module versions for real-time interceptions .............................. 107 7 Historical Data (Retroactive Surveillance) ............................................................... 109 7.1 General ................................................................................................................ 109 7.2 Historical data (retroactive) interception types ...................................................... 110 7.3 Common identifiers and parameters of the handover interfaces ........................... 111 7.4 Formats and coding requirements for retroactive data .......................................... 114 7.5 Historical data handover interface requirements and options................................ 146 7.6 Applicable XML schema version for historical data interceptions .......................... 150 8 Information Requests................................................................................................ 152 8.1 General ................................................................................................................ 152 8.2 Information request types ..................................................................................... 152 8.3 Common identifiers and parameters of the handover interfaces ........................... 154 8.4 Formats and coding requirements for information requests .................................. 157 8.5 Handover interfaces requirements ........................................................................ 199 8.6 Applicable XML schema version for information requests ..................................... 199 9 Security ...................................................................................................................... 200 9.1 Data Protection .................................................................................................... 200 9.2 Hardware Security ................................................................................................ 200 10 List of Technical Specifications ............................................................................... 201 3 Technical requirements for the handover interfaces for the execution of telecommunications surveillance 2 Abbreviations 3GPP Third Generation Partnership Project ASCII American National Standard Code for Information Interchange ASN.1 Abstract Syntax Notation One BA Basic Access (ISDN Basic Access) BC Bearer Capability BRAS Broadband Remote Access Server BÜPF “Bundesgesetz vom 18.
