Abstract
The emergence of quantum computing and Shor’s algorithm necessitates an imminent shift from current public key cryptography techniques to post-quantum-robust techniques. The NIST has responded by standardising Post-Quantum Cryptography (PQC) algorithms, with ML-KEM (FIPS-203) slated to replace ECDH (Elliptic Curve Diffie-Hellman) for key exchange. A key practical concern for PQC adoption is energy consumption. This paper introduces a new framework for measuring PQC energy consumption on a Raspberry Pi when performing key generation. The framework uses both the available traditional methods and the newly standardised ML-KEM algorithm via the commonly utilised OpenSSL library.
