In today’s digital world, trust is paramount for secure online transactions. The eIDAS regulation establishes a comprehensive framework for electronic identification and trust services across the European Union, with Trust Service Providers (TSPs) playing a central role in this ecosystem.
What is a Trust Service Provider (TSP)?
According to Article 3(19) of the eIDAS regulation, a Trust Service Provider is defined as:
“A natural or legal person who provides one or more trust services either as a qualified or as a non-qualified trust service provider.”
In simpler terms, a TSP is an entity that offers digital services designed to create and validate electronic transactions, ensuring their authenticity, integrity, and non-repudiation. These providers act as trusted third parties that enable secure digital communications and transactions between parties who may not know each other.
Key Functions of Trust Service Providers
Trust Service Providers serve several critical functions in the digital ecosystem:
- Identity verification: Controlling and validating data related to user identities
- Digital certificate issuance: Creating and managing digital certificates for authentication
- Timestamping services: Providing proof of when digital transactions occurred
- Electronic signature services: Enabling legally binding digital signatures
- Data protection: Ensuring the security and privacy of user information in compliance with GDPR
- Legal guarantees: Providing security guarantees and legal protections for digital transactions
Types of Trust Services under eIDAS
The eIDAS regulation recognizes several categories of trust services that TSPs can offer:
1. Electronic signatures
Services that enable the creation, verification, and validation of electronic signatures, from simple electronic signatures to qualified electronic signatures with legal equivalence to handwritten signatures.
2. Electronic seals
Digital equivalents of traditional seals used by legal entities to ensure the origin and integrity of electronic documents and data.
3. Electronic time stamps
Services that provide evidence of the existence of data at a specific point in time, crucial for legal and compliance purposes. A timestamp guarantee the integrity of an electronic signature.
4. Electronic delivery services
Services that provide evidence relating to the handling of electronic data, including proof of sending, receiving, and integrity of transmitted data.
5. Website authentication
Services that enable website authentication, allowing users to verify the authenticity of websites and establish secure connections.
Qualified vs. non-qualified trust service providers
The eIDAS regulation distinguishes between two levels of Trust Service Providers:
Non-qualified trust service providers
These providers offer trust services without meeting the specific requirements for qualification under eIDAS. While their services may be legally valid, they don’t benefit from the enhanced legal recognition granted to qualified services.
Qualified trust service providers (QTSPs)
QTSPs represent the highest level of trust under the eIDAS framework. To achieve this status, providers must:
- Meet stringent technical requirements: Including secure infrastructure, robust key management systems, and guaranteed service continuity (typically 99.9% availability)
- Undergo regular audits: Independent assessments to ensure ongoing compliance
- Maintain qualified status: Continuous monitoring and supervision by national supervisory bodies
- Comply with ETSI standards: Adherence to European Telecommunications Standards Institute specifications
- Participate in trust programs: Such as the Adobe Authorized Trust List (AATL) for broader recognition
- Implement cryptographic security: Advanced cryptographic key management and protection mechanisms

Technical and security requirements
Trust Service Providers, particularly qualified ones, must implement robust technical and operational measures:
Infrastructure security
- Secure data centers with physical and logical protection
- Redundant systems ensuring high availability and business continuity
- Regular security assessments and penetration testing
Cryptographic management
- Secure generation, storage, and management of cryptographic keys
- Hardware security modules (HSMs) for key protection
- Strong encryption algorithms and protocols
Operational excellence
- 24/7 monitoring and support services
- Incident response and disaster recovery procedures
- Regular software updates and security patches
Legal recognition and cross-border validity
One of the key advantages of the eIDAS framework is its cross-border recognition mechanism:
- Mutual recognition: Qualified trust services are automatically recognized across all EU member states
- Legal equivalence: Qualified electronic signatures have the same legal effect as handwritten signatures
- Non-discrimination: Trust services cannot be denied legal effectiveness solely based on their electronic format or country of origin
Compliance and regulatory framework
Trust Service Providers operate within a comprehensive regulatory framework that includes:
eIDAS compliance
Adherence to the technical standards, security requirements, and operational procedures defined in the eIDAS regulation and its implementing acts.
GDPR alignment
Ensuring data protection and privacy compliance when processing personal data for trust service delivery, including proper consent management and data subject rights.
National supervision
Regular oversight by national supervisory bodies that monitor compliance, investigate incidents, and can impose sanctions for non-compliance.
Benefits for users and organizations
Working with qualified Trust Service Providers offers numerous advantages:
- Legal certainty: Enhanced legal recognition and protection under European law
- Security guarantees: High-level security measures and protection of user identities
- Interoperability: Services work seamlessly across different platforms and member states
- Compliance support: Assistance with meeting regulatory requirements for digital transactions
- Risk reduction: Professional liability and insurance coverage for service failures

Choosing the right Trust Service Provider
When selecting a TSP, organizations should consider:
- Qualification status: Whether the provider is qualified under eIDAS for your specific needs
- Service portfolio: Range of trust services offered and their technical capabilities
- Geographic coverage: Availability and support in your target markets
