What is a Trust Service Provider (TSP)

Under Regulation (EU) No 910/2014 (eIDAS), a Trust Service Provider (TSP) is defined as “a natural or a legal person who provides one or more trust services either as a qualified or as a non-qualified trust service provider."

TSPs are responsible for assuring the electronic identification of signatories and services by using strong mechanisms for authentication, digital certificates and electronic signatures. eIDAS defines how Trust Service Providers perform authentication and non-repudiation services and how they are to be regulated and recognized throughout EU member states.

A TSP can provide one or more of the following services:

  • Creating, verifying and validating electronic signatures, seals or time stamps, electronically-registered delivery services and certificates that are related to those services.
  • Creating, verifying and validating certificates to be used for website authentication.
  • Preserving electronic signatures, seals or certificates related to those services.
