Curious about what a qualified electronic signature entails? In today's digital age, understanding the significance of this type of signature is crucial. Qualified electronic signatures are a new way to securely sign documents and prove their authenticity. They have changed how agreements are made, making the process easier and faster in many industries.

In the next few sections, we will examine what qualified electronic signatures are, their benefits, and how they change the digital world.

What is a Qualified Electronic Signature

Definition and Key Features

A Qualified Electronic Signature (QES) is a type of electronic signature that utilizes a qualified certificate for authentication. It identifies the signatory and links them to the signature, ensuring accountability. The signatory must have sole control over the signature creation keys for security.

Key Features:

  1. Uses a qualified certificate
  2. Identifies the signatory
  3. Requires sole control over signature creation keys

Legal Framework and Standards

QES are defined and regulated by both the eIDAS framework, which sets standards for electronicQES are defined and regulated by both the eIDAS framework, which sets standards for electronic signatures across EU member states, and the Swiss Federal Act on Electronic Signatures (ZertES). While QES provides legal equivalence to handwritten signatures within the EU and Switzerland, it is essential to check local regulations for recognition in jurisdictions outside these regions, as laws may vary significantly. To ensure compliance, both eIDAS and ZertES outline strict security requirements and certification standards. Only entities that meet these criteria can be approved as Qualified Trust Service Providers (QTSP), authorized to issue the necessary certificates for QES. Compliance with established standards is vital to ensure the validity of QES.

Legal Aspects:

  1. eIDAS and ZertES regulations govern recognition
  2. QTSP issues qualified certificates
  3. Compliance with standards ensures validity

Advanced vs qualified electronic signature: Which signature do I need? 

eIDAS defines three levels of electronic signatures, each suited for different security and legal needs:

  1. Simple Electronic Signature (SES): A basic electronic signature, such as a typed name or digital mark, suitable for low-risk documents with minimal security requirements.
  2. Advanced Electronic Signature (AES): Offers stronger security by verifying the signatory’s identity and detecting document changes after signing, ideal for sensitive documents. However, AES may not provide the same legal weight in certain jurisdictions as QES, which requires additional certification and compliance with specific trust service standards.
  3. Qualified Electronic Signature (QES): The most secure type, legally equivalent to a handwritten signature in the EU, validated by a Qualified Trust Service Provider for high-stakes transactions.

With Sign.Plus, you can seamlessly use all three types of eSignatures, ensuring the right level of security and compliance for any document or transaction.

Why should I use QES, Qualified Electronic Signatures?

Legal Validity and Compliance

Qualified Electronic Signatures (QES) carry the same legal validity as traditional handwritten signatures according to eIDAS regulations. However, specific use cases, such as signing wills or property deeds, may still require handwritten signatures depending on national legislation, even within the EU. Compliance with legal standards is maintained through rigorous auditing and management practices. Non-compliance can have serious repercussions for both signatories and service providers.

Security and Trust

QES guarantees data integrity and detects any alterations made post-signature, ensuring document authenticity. This assurance is based on current eIDAS and ZertES standards, and it is important to stay updated on advancements in cryptographic technologies and evolving regulatory frameworks. The identity verification processes in QES creation establish trust among the parties involved.

Efficiency and Cost Savings

Adopting QES leads to reduced paperwork and administrative burdens, simplifying processes efficiently. Businesses benefit from faster transaction times due to the streamlined workflow enabled by QES. Long-term cost savings are possible through decreased fraud instances and error reduction.

Cross-Border Agreements

QES facilitates seamless digital transactions across different jurisdictions within the European Union (EU). It allows parties from different countries to sign contracts electronically with legal validity. The EU's eIDAS Regulation allows countries in the EU to recognize Qualified Electronic Signatures (QES) from each other. This makes it easier to agree on documents and contracts across borders.  This recognition promotes trust in cross-border transactions, boosting international trade and cooperation.

In international trade, QES is essential in ensuring the authenticity of documents like customs declarations and contracts. By using QES, businesses can expedite negotiations and agreements with overseas partners securely.

QES offers enhanced security measures for sensitive information exchange within public sector entities. In applications like e-voting, QES ensures the integrity of voting processes by verifying the identity of participants and securing their votes.

In digital identity verification, Qualified Electronic Signatures (QES) offer a trustworthy way to confirm people’s identities online. Using QES in government services has made processes like issuing permits and licenses quicker and more secure. These implementations enhance efficiency while maintaining data integrity and confidentiality.
