QSNARE

QSNARE is an open-source software toolkit designed to model, simulate, and analyze quantum-resistant networking protocols. The term is used in multiple projects, but the core concept centers on a modular framework for assessing how post-quantum cryptography affects network security and performance. It aims to provide a practical environment for evaluating protocol designs under quantum threat models.

The architecture of QSNARE includes a core discrete-event simulation engine, a protocol library with configurable cryptographic suites, and a suite of metrics for latency, throughput, reliability, and security properties. The toolkit supports plugin-based expansion, allowing researchers and developers to implement new protocols or cryptographic schemes by writing plugins in languages such as Python or C++. It emphasizes reproducibility, reproducible experiments, and the ability to compare different algorithmic choices within consistent network topologies.

Common applications include research and education, where QSNARE is used to compare post-quantum algorithms in realistic topologies, study performance trade-offs, and illustrate concepts of quantum-threat planning in network security. It is also employed to prototype secure session establishment, key exchange, and data transport mechanisms that remain robust against quantum adversaries, enabling hands-on exploration of PQC deployments.

Development and reception: QSNARE is maintained by a community of researchers and practitioners and is distributed under an open-source license. Documentation and tutorials accompany the project, and contributions from academia and industry are encouraged.
