Advanced Electronic Signatures (AES)
What are AES and when can you use them? Understand the benefits and legal validity of Advanced Electronic Signatures for digital transactions.
An Advanced Electronic Signature (AES) is a type of electronic signature that offers a higher level of security compared to simple e-signatures. It is designed to provide legal certainty and greater proof of the signer's identity, which makes it ideal for situations where higher levels of trust and verification are required. AES is legally recognized across the EU and Switzerland, providing a secure and reliable way to sign contracts, agreements, and other important documents digitally.
Features of Advanced Electronic Signatures (AES)
Advanced Electronic Signatures (AES) combine several key features to ensure a high level of security, authenticity, and legal compliance:
- Identity Verification: AES requires the signer's identity to be verified through a secure process, such as using a digital certificate, smart card, or two-factor authentication (2FA). This ensures that only the intended person signs the document.
- Document Integrity: AES ensures that the signed document remains intact after the signature is applied. Any alterations made to the document after signing will invalidate the signature, guaranteeing its integrity.
- Non-Repudiation: AES provides evidence that the signer cannot deny having signed the document. This is achieved through cryptographic techniques and a secure audit trail, which records the time and date of the signature and the signer's details.
- Compliance with Legal Requirements: AES meets the legal requirements for electronic signatures under the eIDAS Regulation in the EU and ZertES in Switzerland. This ensures that AES is legally binding and admissible in court.
Due to these robust features, AES is widely used for formal agreements and transactions where the highest level of trust is required.
Legal Validity of AES
Advanced Electronic Signatures (AES) are legally valid under both Swiss law (ZertES) and the EU’s eIDAS Regulation. Here are some key points regarding their legal validity:
- Swiss Law (ZertES): AES is legally recognized as a valid form of signature for contracts and documents under Swiss law. It is considered legally binding and equivalent to a handwritten signature, provided it meets the technical requirements for identity verification and document integrity.
- EU eIDAS Regulation: Under the eIDAS Regulation, AES is recognized as a legally valid signature for digital transactions across the EU. AES can be used for various types of agreements, including commercial contracts, financial agreements, and business transactions.
- Admissibility in Court: Documents signed with AES are legally admissible as evidence in court. AES ensures non-repudiation, meaning the signer cannot dispute their involvement in the signing process.
Due to these legal protections, AES is suitable for formal agreements where legal certainty and document integrity are crucial.
Use Cases for AES
Advanced Electronic Signatures (AES) are suitable for a wide range of applications where security and legal compliance are paramount:
- Business Contracts: AES is commonly used for signing formal business contracts, including partnership agreements, service contracts, and supply agreements. It ensures both parties' identities are verified and that the document cannot be altered after signing.
- Financial Transactions: AES is used for high-stakes financial agreements, such as loan contracts, mortgage agreements, and insurance policies, where legal certainty and security are required.
- Legal Documents: AES is suitable for signing legal documents such as powers of attorney, litigation-related documents, and corporate filings, ensuring full compliance with the law.
- Healthcare Agreements: AES is increasingly used in the healthcare industry for signing medical contracts, patient consent forms, and health-related documents, ensuring privacy and security of sensitive data.
- Cross-Border Transactions: As AES is recognized under eIDAS and ZertES, it is widely used for cross-border transactions between businesses and individuals in Switzerland and the EU.
AES is ideal for any digital signature application that requires higher security and legal protection, making it suitable for both personal and business use.
FAQ – Common Questions about Advanced Electronic Signatures (AES)
What is the difference between AES and QES?
AES (Advanced Electronic Signature) offers a high level of security and is legally valid for most formal agreements. However, QES (Qualified Electronic Signature) offers the highest level of security and is equivalent to a handwritten signature under the law. QES is typically required for high-risk transactions or when stricter legal requirements are in place.
When should I use an AES?
AES should be used when signing formal contracts, business agreements, or legal documents that require a higher level of security and identity verification. AES is ideal for scenarios where a higher level of trust is needed, but a QES is not required.
Is AES legally binding?
Yes, AES is legally binding in both Switzerland (under ZertES) and the EU (under eIDAS). It provides the same legal effect as a handwritten signature, ensuring that the signed document is enforceable in court.
