Crypto: EC J-PAKE

The EC J-PAKE sample demonstrates how to do password-authenticated key exchange using the elliptic curve (EC) version of the password-authenticated key exchange by juggling (J-PAKE) protocol.

Requirements

The sample supports the following development kits:

Overview

The sample performs the following operations:

  1. Initializes the Platform Security Architecture (PSA) API.

  2. Goes through the steps for J-PAKE on server and client sides.

  3. Verifies that the derived keys are the same.

Building and running

Testing

After programming the sample to your development kit, complete the following steps to test it:

  1. Connect to the kit with a terminal emulator (for example, nRF Connect Serial Terminal). See Testing and optimization for the required settings and steps.

  2. Compile and program the application.

  3. Observe the logs from the application using a terminal emulator.
