While standards are well in place for signatures created locally by end-users, the market take-up of these solutions has been significantly low due to the unfriendly requirement for the end-user to have a physical device (e.g. dongle, smart card). The market has then been moving to signature creation services hosted in the cloud and managed by Trust Service Providers. These solutions imply moving the user private key from a user-owned device to the cloud and raise security challenges in order to ensure the security of the service. ETSI started to work on this topic in order to bring technical interoperability as well as a high level of assurance of the trust services building on the CEN standard for "server signing". The objective of the standards is to meet the aims of the eIDAS Regulation as well as to meet the general requirements of the European and international community.
The workshop discussed about standardization for remote signature creation services provided by Trust Service Providers, addressing business cases, audit requirements and protocols.


1. Make users of the standards aware of:

  • Scope of standards and general approach being taken
  • Operation of Protocols
  • Main "policy" requirements to be covered by audit

2. Get an idea of some example business use cases

3. Collect initial feedback on standards and public review process

Target audience

This event was of particular interest for:

  • Remote signature creation service providers and manufacturers,
  • Major users of signature creation services (e.g. Banks)
  • Audit Bodies,
  • Supervisory Bodies,
  • Policy makers,
  • Other eSignature/eSeal related trust providers.
