The Journey of the Lissi ID-Wallet towards eIDAS 2 and EUDI-Wallet compatibility

In response to the revision of the eIDAS regulation, the European Union is introducing a common set of standards and technical specifications, which are designed to facilitate the seamless issuance, presentation and verification of verifiable identity data across borders. We are excited to announce that the Lissi ID-Wallet supports selected standards, as we will further elaborate in this article.

The technical standards of the eIDAS 2.0 regulation are defined in the Architecture Reference Framework (ARF). These standards are crucial as every European Digital Identity Wallet (EUDI-Wallet) and applications interacting with it will need to support the required standards and technical specifications, which include communication protocols and credential formats among others. At Lissi, we have extended our wallet to ensure alignment with core standards:  

Communication protocols: Currently, the only proposed communication protocol is OpenID4VC (OpenID for verifiable credentials), which we integrated as the worlds first wallet as part of a prototypical implementation in 2021. It is mandated for the presentation of the foundational identity (eID or PID - Person Identification Data), which will be issued by a member state. With the current status of the regulation, member states will have the flexibility to choose their own issuance protocols for the PID, however Qualified and non-qualified electronic attestations of attributes QEAA / EAA need to be issued via this protocol. 

Credential formats: The ARF standards currently propose multiple credential formats, including two different types of verifiable credentials as well as an ISO mobile driver's license (mDL) credential format. In order to use the benefits of multiple credential formats, the PID will be issued as verifiable credential and ISO mDL simultaneously. For all other (qualified) electronic attestations of attributes (such as an educational degree, employee pass, customer card, insurance claim etc.) the issuer is free to choose one of the supported types of credential formats according to the ARF. 

We are thrilled to announce that the Lissi ID-Wallet, is now supporting  these new crucial standards:

 

  • OpenID4VC, which includes OpenID4VCI (OpenID for Verifiable Credential Issuance) and OpenID4VP (OpenID for Verifiable Presentations).
  • SD-JWT-based Verifiable Credentials with JSON payloads (SD-JWT VC).

The wallet is publicly available as a beta version for both iOS (TestFlight) and Android platforms. We encourage developers of issuance and verification software to test their implementations against our wallet to ensure interoperability and seamless functionality. We currently test our own issuance and verification software with selected clients. If you are interested in implementing use cases you need an EUDI-Wallet connector software like the one we provide. 

The new standards are implemented based on the High Assurance Interoperability Profile (HAIP). It's worth noting that there are other important standards as part of the eIDAS 2.0 regulation, such trust lists, public key infrastructure, digital signatures and more, which we will explore in future articles and won’t go into detail here. 

In addition the Lissi ID-Wallet still supports the following standards which are not defined in the ARF, however, are used in many other identity projects:

  • The DIDcomm communication protocol
  • Anonymous credentials also called “Anoncreds”

As we witness the European community unite around a shared vision for a trusted digital future, we are proud to offer solutions that facilitate the required testing and integration of these pivotal standards. We look forward to continuing our journey alongside you, contributing to a harmonious and interconnected digital Europe.
