CSD-JWT CONSTRAINED

• Overview
• Usage

This test retrieves timings, CPU, RAM usage from attempting to issue a Verifiable Presentation using Nordic Semiconductor devices. Specifically, the test is executed on a nrf52840dk development kit.

Overview

The test performs the following operations:

1. VC parsing and decoding using the parson library to handle JSON structures.
2. Modification of the VC in two formats: sd-jwt and csd-jwt. The program clones the VC and substitutes respectively the Salt-Value Container and the Witness-Value Container to only disclose a subset of claims.
3. Signs the issued VP with a ECDSA signature using Zephyr's libraries.
4. Produces timings with regards to the issuance of the VP. Also produces CPU and RAM utilization.

Usage

In prj.conf enable and disable testing of SD-JWT and CSD-JWT respectively using the macros CONFIG_TEST_CSD_JWT, and CONFIG_TEST_SD_JWT. In prj.conf allow usage of either VCs with 10 claims or 100 claims by switching the macro CONFIG_USE_SHORT_VCS.
