Secure Messaging with Kyber, Dilithium, and AES-256

This project demonstrates how to securely encrypt packets of messages using AES-256 encryption. Keys are securely exchanged using Kyber, a post-quantum cryptographic algorithm, and authenticated using Dilithium ensuring protection against both classical and quantum attacks.

Steps to Run the Test

1. Activate the environment

   source venv/bin/activate

2. Git clone the pqc_aes_multipath repo:

https://github.com/abhisekjha/NextGenSecureMessaging.git
cd pqc_aes_multipath

3. git clone Kyber based PYKY

https://github.com/asdfjkl/pyky.git

4. Set and verify Pythonpath:

export PYTHONPATH=/path/to/pqc_aes_multipath:/path/to/pqc_aes_multipath/pyky:/path/to/pqc_aes_multipath/dilithium-java
echo $PYTHONPATH

5. Set the JAVA_HOME to other version()

export JAVA_HOME=`/usr/libexec/java_home -v 11`
export PATH=$JAVA_HOME/bin:$PATH

6. Build the dilithium project:

mvn clean install

7. Set Java environment for JDK 8 and build with Gradle:

/usr/libexec/java_home -v 1.8
export BC_JDK8=/Library/Java/JavaVirtualMachines/temurin-8.jdk/Contents/Home
export JAVA_HOME=$BC_JDK8
export PATH=$JAVA_HOME/bin:$PATH

java -version
./gradlew clean
./gradlew build --refresh-dependencies

8. Install requirements.txt

pip install -r requirements.txt

8. Run test cases using make

make

Acknowledgements

I would like to thank the pyky repository and dilithium-py for providing the implementation of the Kyber cryptographic algorithm and Dilithium Implementation, which was used in this project.
