Securely deploy and operate EUDI wallets at national scale, without binding trust to devices or smartcards

Operating a European Digital Identity Wallet is not just about launching an app. It requires a qualified cryptographic environment that works across devices, supports cross-border interoperability, and remains manageable at national scale. Ubiqu provides certified backend building blocks that enable governments to deploy and operate EUDI wallets with architectural control and long-term flexibility.

Ubiqu’s Remote Secure Element provides a remote WSCD/WSCA environment implemented inside certified HSMs, where both key protection and signing policy enforcement operate within the same secure boundary rather than on the end-user device. Keys never leave the protected environment and can only be used when all defined conditions are met. This removes dependency on device-bound secure elements and enables governments to scale wallet security by increasing certified HSM capacity instead of distributing enforcement logic across millions of devices.

Building sovereign EUDI wallet infrastructure


Building sovereign EUDI wallet infrastructure requires a qualified cryptographic foundation that governments control, scale, and evolve without dependence on devices, platforms, or external vendors.

  • Operating a national EUDI wallet infrastructure
    Deploy and run wallet security through a remote WSCD/WSCA environment, avoiding dependency on device-bound secure elements and mobile platform constraints.
  • Issuing identity into a qualified cryptographic environment
    Bind verified citizen identities to a certified remote secure element that supports qualified signatures and high-assurance transactions.
  • Enabling qualified signatures at population scale
    Provide legally valid signatures without distributing cryptographic enforcement across millions of personal devices.
  • Supporting multiple issuing authorities
    Allow ministries, agencies, and public bodies to issue credentials and attributes into a shared, certified backend without duplicating secure element infrastructure.

“Running trust services should not force providers to choose between control, scalability, and long-term flexibility. When security is enforced by architecture rather than surrounding systems, those trade-offs disappear.”

The critical design decision behind every EUDI wallet

Most trust-service infrastructure is delivered as an end-to-end platform or as a fully outsourced QTSP service. Buying signatures typically means adopting the provider’s entire stack and workflows, leaving little room for architectural choice or adaptation.
Although keys are often stored in HSMs, access rules are commonly enforced outside the HSM, creating complex and high-risk infrastructure that is hard to secure, scale, and evolve.

A wallet security model that scales without device dependency

Ubiqu provides a remote WSCD/WSCA environment inside certified HSMs, creating a sovereign and scalable secure element layer for the wallet. Keys remain within the protected boundary, and signing policies are enforced there rather than on citizen devices. This allows governments to operate qualified wallet services at national scale and adapt over time without redistributing secure elements across millions of devices.

Operationalising the Remote Secure Element

The Remote Secure Element is designed to be used across multiple identity and trust products, not as a standalone component. It acts as a shared security foundation that can be applied where high-assurance identity, access, or trust services are required, while allowing each product to evolve independently.

We provide the backend technology needed to build and run an EUDI wallet. It handles secure identity usage, authentication, and credential operations in line with the EUDI architecture, without depending on specific devices or phone capabilities.

The organisational identity wallet enables secure access to applications, systems, and physical environments using a single digital identity. It supports authentication and authorisation based on roles and verified attributes, while keeping the user experience simple and consistent.

Our trust-service components enable organisations to issue and operate services such as signatures, seals, timestamps, and attestations. They are designed to integrate into existing architectures without forcing adoption of a full platform. Trust enforcement and scalability are handled by a common security backbone.

We enable organisations to build or evolve towards qualified trust services at their own pace. Instead of adopting a monolithic QTSP platform, organisations can assemble the required components and retain control over their architecture. Certified security components provide the foundation when qualification is required.
