EviSign NFC HSM
Advanced Contactless Electronic Signature
EviSign NFC HSM: Advanced Electronic Signature Technology by Freemindtronic
EviSign NFC HSM is Freemindtronic’s finished advanced electronic signature technology for compatible DataShielder NFC HSM devices. It links the signature to the signatory, identifies the signatory, keeps the signing means under the signatory’s control through a contactless hardware device and detects later changes to signed data. Therefore, EviSign NFC HSM follows the logic of an advanced electronic signature under eIDAS Article 26, while it does not claim qualified electronic signature status, QSCD status, QTSP status or a qualified certificate.
NFC HSM Electronic Signature for Secure Document Signing
- EviSign NFC HSM gives users a hardware electronic signature method where the signing identity, key status, validity period and signature credits stay linked to a compatible Freemindtronic NFC HSM.
- The technology combines an ES256 / ECC P-256 signature component with an ML-DSA post-quantum component in the EviSign evidence envelope.
- Moreover, the compatible DataShielder device keeps the signing means under physical user control during NFC signature operations.
- As a result, EviSign NFC HSM delivers an advanced electronic signature technology under eIDAS Article 26, without presenting itself as a qualified electronic signature.
EviSign Browser Extension and NFC Digital Signature Workflows
The EviSign browser extension helps users verify signatures and handle cryptographic workflows inside the Freemindtronic ecosystem. In addition, it keeps sensitive signing operations connected to compatible NFC HSM technology instead of relying on a cloud signing account.
EviSign supports Chromium and Firefox based web browsers according to the deployed configuration and the DataShielder product capability matrix.
EviSign NFC HSM works with the Freemindtronic application ecosystem and uses segmented-key authentication technology from NFC HSM.
eIDAS Article 26 Advanced Electronic Signature
EviSign NFC HSM implements a technical advanced electronic signature approach under eIDAS Article 26. It links the signature to the signatory, identifies the signatory through an EviSign identity record, gives the signatory control of the signing means through a compatible DataShielder NFC HSM and detects later changes to signed data.
However, a qualified electronic signature belongs to another legal category. It requires a qualified certificate, a qualified trust service provider and a qualified signature creation device. EviSign NFC HSM does not claim these qualified statuses.
For PDF workflows, EviSign NFC HSM uses a PAdES-B-technical path with an embedded CMS signature over the PDF ByteRange. In parallel, the EviSign envelope can carry the hybrid ES256 plus ML-DSA proof. Therefore, the page distinguishes technical proof, advanced electronic signature technology and qualified eIDAS signature status.
Multilingual EviSign NFC HSM Application
International
The application supports 15 languages: Arabic, Catalan, Chinese, English, French, German, Hindi, Italian, Japanese, Portuguese, Romanian, Russian, Ukrainian and Spanish.
Moreover, the app selects the smartphone language automatically, which helps organisations deploy EviSign NFC HSM electronic signature workflows across international teams.
Peace of mind solution
Users can install EviSign NFC HSM easily and work in their own language. At the same time, they keep the security model of a physical, contactless signing device.
More languages
Freemindtronic can add more languages for specific deployment needs.
Compatible DataShielder NFC HSM Products
EviSign NFC HSM runs only on the compatible DataShielder range. The supported products are DataShielder NFC HSM Master, DataShielder NFC HSM Lite, DataShielder NFC HSM Auth, DataShielder NFC HSM M-Auth, DataShielder NFC HSM Lite 5 and DataShielder Defense NFC HSM.
The DataShielder NFC HSM Starter Kit may include a compatible DataShielder device. Therefore, EviSign availability follows the actual device capability matrix, not the kit name alone.
EviSign NFC HSM also benefits from Freemindtronic technologies such as EviCypher and EviPass when the product matrix enables them. EviCypher extends secure encryption and OpenPGP-oriented use cases, while EviPass focuses on strong authentication.
In addition, EviSign NFC HSM supports secure document signing through two complementary paths. The detached EviSign envelope protects the original file and can carry the hybrid ES256 plus ML-DSA proof. The PDF path can publish a signed PDF copy, named with the Signed-by-DataShielder prefix, in a DataShielder signed-document folder.
EviSign NFC HSM Technology is Eco-Friendly
Freemindtronic designs its NFC HSM technologies for low-energy operation, long service life and reduced cloud dependency.
Cloudless
EviSign NFC HSM supports air-gapped electronic signature workflows because it keeps sensitive signing assets in NFC memory rather than in a cloud account. As a result, users reduce unnecessary cloud dependency.
Long service life
The NFC HSM hardware preserves data for long periods without continuous power. Therefore, it supports durable identity and key-management use cases.
NFC Energy Harvesting
Compatible devices use ISO 15693 NFC technology with energy harvesting. Consequently, the NFC field powers contactless operations during use.
Batteryless
The NFC HSM device does not need a rechargeable battery for its core contactless memory and NFC signing operations.
Recyclable
The electronic card complies with the European RoHS directive. In addition, the coating and ABS plastic shell can follow the relevant recycling stream.
Second Hand Market
A compatible NFC HSM device can return to factory configuration. Therefore, users can prepare it for reuse when appropriate.
Summary of EviSign NFC HSM
EviSign NFC HSM gives compatible DataShielder products an advanced contactless electronic signature technology. It links the signature to the signatory, identifies the signatory, keeps the signing means under user control and detects later data changes. Moreover, it combines a hardware NFC HSM workflow with hybrid ES256 and ML-DSA evidence. However, it does not claim qualified electronic signature, QSCD, QTSP or qualified certificate status.
