Explanatory Videos
Our explanatory videos break down complex hardware security concepts into clear, visual stories. They showcase how FortifyIQ’s technologies detect and prevent side-channel and fault-injection attacks, strengthen cryptographic modules, and enhance overall device resilience.
Attackers can now breach your device for just a few hundred dollars unless robust security measures are in place. Watch our webinar to learn how our solution ensures you no longer have to compromise between security and functionality.
Here we present RAMBAM, our patented novel concept of designing countermeasures against side-channel attacks and SIFA on AES using redundant representations of finite field elements. It enables trade-offs between gate count, maximal frequency, performance, level of robustness to first and higher-order side-channel attacks and SIFA-1. We present an analytical model that explains the leakage reduction, and a leakage assessment using TVLA methodology on an FPGA board, showing resilience to at least 348M traces with 16 Sboxes.
We present Carry-based Differential Power Analysis (CDPA) — a new side-channel attack targeting algorithms that use arithmetic addition. Applied to HMAC-SHA-2, CDPA enables full key recovery from power traces, both in simulation and on FPGA hardware. With as few as 30K traces, secret keys can be recovered in some cases, allowing for forging the HMAC-SHA-2 signature of any message, and with 275K traces, the success rate reaches 100%. This demonstrates that even pure hardware implementations of HMAC-SHA-2 are vulnerable unless properly protected. To our knowledge, this is the first successful non-profiling attack on hardware HMAC-SHA-2.
