 5Go phreaking
 ====================
 
-This service is a basic simulation of a standalone 5G network - implementing a registration protocol inspired by [NAS/5GMM](https://www.etsi.org/deliver/etsi_ts/124500_124599/124501/17.07.01_60/ts_124501v170701p.pdf) and the [NGAP](https://www.etsi.org/deliver/etsi_ts/138400_138499/138413/16.02.00_60/ts_138413v160200p.pdf) protocol. The service consist of two docker images:

The service consist of two main components:
 
 - Core: TCP server (internal port 3399) simulating 5G Access and Management Function (AMF) capabilities that can manages user equipment registration, authentication and security. The core also has a rudimentary User Plane Function (UPF), so when the phone is registered it can "request data from the internet". The response is just a hardcoded HTML page.
 - UE (User Equipment): TCP server (internal port 6060) simulating a "5Go-enabled" phone, which connects to the Core and makes a fake [Gohper protocol](https://en.wikipedia.org/wiki/Gopher_(protocol)) request to the "internet". It also contains a gRPC server (internal port 9930) to simulate the operating system GPS API of the phone. It is used by checker to put flags on the UE.
 
-In addition to these two components, a binary called `gNB` is provided. Which is a fake basestation to facilitate communication between the UE and Core, and make the service useable/interactive. Source code for this binary is in the `service_hidden` folder, which is not given teams playing this service. The `setup.sh` script in the hidden folder is used to compile the binary and copy it over to the `service` folder.
