For mobile/native applications, Link11 WAAP authenticates the client itself and all communication with it.

We provide an SDK (for both Android and iOS) to our customers, who rebuild and publish their applications with the SDK embedded. In use, it signs the application, authenticates the device, and verifies user identity.

All communications occur over TLS and include an HMAC signature (a cryptographic identity mechanism on the client side) to harden communications between the mobile/native application and the microservice/API endpoint. The signatures are non-reproducible, non-guessable, non-repeating (they are unique per session and per request), and are based on dozens of parameters (time-based, location-based, environment-based, and more). They provide a reliable, secure mechanism to verify that the packets are originating from a legitimate user, and not from an emulator or other bot.

For more information about the SDK and how to use it, see .
