To validate the efficiency of the CB-RAN architecture, the following applications will be implemented in this testbed:

1. Traffic management (critical machine type communications-MTC): the testbed will connect IoT devices that simulated traffic lights through 5G indoor links with the following requirements: (i) reliable and resilience connectivity; (ii) the IoT devices (simulated traffic lights) can be added/removed over time (ad-hoc connectivity); and (iii) data privacy and security are of high importance due to regulations. Traffic management is implemented using the connectivity part, and PQC functionalities will be foreseen to improve end-to-end data communication security. Crypto-agile libraries shall be integrated to generate E2E encryption using new PQC libraries, which are being standardised by NIST.
2. IoT sensor measurements (massive MTC): sensor measurements are based on a traffic simulator able to yield a massive IoT scenario that needs to support high-uplink traffic and mobility management. An IoT simulator will generate a large number of messages with the same format as the IoT sensors. Large volume connection client/server application will demonstrate crypto agility and will collect performances of new PQC algorithms to compare with the ones currently in use (e.g., RSA, DSA, etc.).

The PQC Encrypt/decrypt modules will be able to deploy PQC cryptography. A PQC library is needed in both IoT devices and edge IoT applications. The PQC algorithm should be selected based on the computational capacity of the IoT devices, while the provider of the IoT devices should identify the libraries that support PQC in the device and in the edge application that is receiving the data from the sensors.
