Home Office

Member of the Home Office Expert Panel on Digital Signatures in the Acquisition of Communications Data within the Criminal Justice System. The Digital Signature Expert Panel has a mandate to develop a means of adding evidential force to the recording of the processes involved in authorizing, acquiring and disclosing communications data.

The purpose and background

The Communications Capabilities Development programme brings together work to ensure that, in a changing communications environment, communications data can continue to protect the public and save lives. The Evidential Communication Data theme has commissioned a project to implement the use of digital signatures in the lawful acquisition of communications data under the provisions of the Regulation of Investigatory Powers Act 2000 (RIPA). The project has two key strands of activity which will provide for the digital signatures in the use of evidential communications data in the Criminal Justice System; evidencing a technical solution, and business change.


The subject matter experts are assisting in defining the technical and procedural requirements to enable the use of digitally signed communications data in evidence. In practice, the requirement of the Expert Panel is to assist with:

1. A critical review of the technical specifications for the implementation of digital signatures through a specified set of acquisition methods including RDHI and Portals.

2. Advising on the level of Information Assurance required in this context.

3. Advising on the practical considerations for the implementation of digital signatures in the Criminal Justice System.
