5G NTNSecurity with Blockchain

This code is intended for the work "Blockchain-Enhanced Security for LEO Satellite Firmware Updates in Beyond-5G NTN Networks"

Build docker images for Free5GC core network:

Build core base image from directory: ./build/f5gc_core

In the directory: ./build/f5gc_core BUild the docker images with the tag defined in the docker-compose.yaml file.

Build satellite emulator : opensand

The satellite emulator containers will build upon runing the docker-compose.yaml file from directory: ./build/opensand

Three containers: Gateway, Satellite, and Terminal will be in runing state

Build RAN image: UERANSIM

Build base images from ./build/ueransim_base and bothe cmake and ueransim base images should be built

docker build -t cmake:v3.2 -f ./build/ueransim_base/cmake/Dockerfile

docker build -t ueransim:base -f ./build/ueransim_base/ueransim/Dockerfile

Build gNB and UE from ./build/ueransim_ran

docker build -t gnb:master -f ./build/ueransim_ran/gnb/Dockerfile

docker build -t ue:master -f ./build/ueransim_ran/ue/Dockerfile

Built Ganache local blockchain image

Build docker image for Ethereum local blockchain:

docker build -t trufflesuite/ganache-cli:latest -f ./ethereum/Dockerfile

Built middleware image

docker build -t ntn-5g-bl-middleware:latest -f ./middleware/DockerfileMiddleware

The end-to-end blockchain based 5G NTN networks are shown below:

These fugures shows the overall build network for secure blockchain based 5G NTN network

Start the network:

Start Ganache CLI: Ganache starts listening at port 8545

docker compose -f docker-compose-ganache.yml up

Compile and deploy smart contract:

From the directory: ./ethereum

truffle compile

This will create the compiled ABI file including the bytecode in the directory: ./ethereum/build/contracts

truffle migrate --network development

This will deploy the compiled smart contract into the Ethereum Virtual Machine (EVM) and contract address is returned from the lockal blockchain

Start Midleware: Listens at port 5000

Fetch the contract address and private key of the first ethereum account to which the contract is deployed

Sample account address and key pair:

0x001c62F91F80A5a0eeCc6F60B78F641911024257 : 0x5be3d9d215fc14b01f67630ff66faca9a15f27bcd5bf848f3cb4fbe95eddc7ef

docker compose -f docker-compose-middleware.yml up

Deploy the 5G NTN network to interact with Ganache via the middleware

docker compose up

The satellite components are configured to interact to Ganache

Now an end-to-end GTP tunnel will be established if the traffic going to the satellite network is authenticated by the blockchain
