Talk to us if you need a whitelabel solution of our smartcard. We provide support for different protocols and designs.

Use Case:
App Encryption

An app containing sensitive data can be fully encrypted. The user is prompted to tap the correct smartcard. If the correct smartcard is used, the content will be decrypted and temporary access is allowed.

New content (e.g. files, incoming messages) are encrypted without the smartcard (using the public key associated with this card). This allows, for example, to encrypt incoming messages directly for a messenger app without holding the smartcard against the device.

This is not a simple unlock screen, it uses real public-key cryptography to encrypt the whole app database!

Use Case:
Server Authentication

Due to its public-key encryption scheme, it can be utilized to provide authentication, for protocols such as SSH, without requiring central identity servers.

This is helpful to maintain critical infrastructure that is not necessarily connected to the Internet. A certificate scheme, such as SSH certificates or X.509 certificates can be utilized for key management.
