# 1 Introduction

The purpose of this document is to describe the processes concerning the management of approved trust services in the X-Road central server.

The use cases include verifications that take place, and the main error conditions that may be encountered during the described process. The general system errors that may be encountered in most of the use cases (e.g., database connection errors or out of memory errors) are not described in this document.

The use cases assume that the X-Road software components involved in the use cases are installed and initialised.

The use cases including a human actor (the level of the use case is user task) assume that the actor is logged in to the system and has the access rights required to carry out the use case.

# 2 Overview

The certification services and timestamping services approved by the X-Road governing agency provide trust services for the members of an X-Road instance.

The approved trust services are described in the central server. The information on the approved trust services is distributed to the security servers as a part of the global configuration.

The security servers verify that the certificates, OCSP responses and timestamps used in the communication process between the X-Road members are provided by approved trust services.

# 3 Use Case Model

# 3.1 Actors

The use case model for trust service management in the central server includes the following actor.

  • CS administrator (central server administrator) – a person responsible for managing the central server.

Relationships between the actor, system and use cases are described in Figure 1.
