Keysight Introduces New Testing Capabilities to Strengthen Post-Quantum Cryptography

01/21/2026

Keysight Technologies, Inc., has announced industry-first testing capabilities designed to test the robustness of post-quantum cryptography (PQC). This latest addition to Keysight Inspector is a notable expansion of the comprehensive platform that helps device and chip vendors identify and fix hardware vulnerabilities.

Quantum computing is designed to substantially accelerate complex calculations. This development will inevitably threaten existing encryption technologies. Algorithms like RSA and ECC, proven and robust in the current conventional computing era, could be easily circumvented. As the industry looks to remain resilient both now and in the future, this means developing new PQC encryption algorithms. This will be important for applications where encrypted data is captured on the assumption it can be decrypted later. However, new technologies assumed to be resilient against post-quantum attacks may be vulnerable to existing hardware-based attack methods.
