How to Secure Embedded PQC Implementations

+ Photonics

Assess Embedded PQC Implementation Security

The assessment requires an embedded implementation of post-quantum cryptography (PQC), its target hardware, and security analysis of how the cryptographic operations execute on that platform. Evaluate implementation-level exposure rather than relying solely on the mathematical strength of the selected algorithm. Examine side-channel leakage, fault-injection susceptibility, key handling, and implementation behavior under relevant attack conditions.

Use the assessment results to identify implementation weaknesses and determine appropriate countermeasures. Apply layered mitigations through secure coding practices, attack-specific countermeasures, secure key management, and formal verification where applicable. Repeat security analysis after mitigation to evaluate whether the implementation continues to expose information or behavior that could compromise the intended PQC protection.

Embedded PQC Security Assessment Solution

Assess the implementation of post-quantum cryptography (PQC) on the target embedded platform and identify security weaknesses that can exist even when standardized algorithms are used. Keysight PQC Security Services provides guidance, support, and mitigation advice for secure PQC implementations. The assessment should consider side-channel and fault-injection exposure alongside secure coding, key management, and verification practices. This approach addresses implementation risks associated with deploying PQC on resource-constrained embedded hardware, where processing capability, memory, power, and cost can affect implementation choices. Findings can then guide mitigation strategies appropriate to the device architecture and its intended security requirements.
