Requirements

Thw topic lists the minimum requirements that the mobile application, as well as the devices integrating the Nevis Mobile Authentication SDK need to meet.

We first show you what is required for the development phase of the mobile application, then what changes you need to make to move from the development phase to the phase where the mobile application is prepared for a production release.

The SDK has to be compatible with the version deployed in the Nevis Mobile Authentication backend.

Mobile device requirements

The following prerequisites have to be met by any mobile device to run an application integrating the Nevis Mobile SDK:

1. The client device has to fulfill the minimum OS requirements listed for the individual platforms.
2. The SDK requires the presence of the following:
   • TEE on the Android device. If the device does not provide a TEE, the SDK returns an exception during initialization.
   • Secure Enclave on iOS device. All supported iOS devices provide a SE.
3. A device locking mechanism has to be in place.
4. The device is not to be rooted or jailbroken.

Nevis backend requirements

• Customer Authentication Cloud: Fully supported.
• Nevis Software Delivered / Identity Suite: Requires the nevisFIDO component version 1.11.0 or later, which applies to nevisAppliance versions 2.202102.x or later, as well as the LTS21 release.

Networking/TLS requirements

The usage of self-signed certificates or cleartext non-HTTPS traffic is not supported, trusted Root-CA signed certificates are required. One of the reasons are strict requirements imposed by Apple regarding trusted TLS certificates.
