Ultra-Low-Power AES Encryption Core with Full Mode Support and Formally Proven SCA Protection
FortifyIQ’s Low-Energy AES IP core delivers AES-128/256 encryption-only with support for all major modes, including ECB, CBC, CTR, GCM, and XTS, while maintaining ultra-low power consumption and a compact footprint. Designed for moderate performance in constrained embedded systems, it is ideal for secure sensors, wearables, and low-power controllers. The core integrates STORM, a lookup table-based side-channel protection scheme derived from RAMBAM, which includes a formally proven guarantee of resistance against side-channel attacks (SCA). These protections are implemented entirely at the RTL level, making them layout-independent and technology-agnostic. Built to support systems targeting FIPS 140-3 and Common Criteria, this core offers an optimal blend of energy efficiency, full-mode AES capability, and certified-ready physical security for modern low-power platforms.

“Summary. The leakage analysis (Welch t-test) on over 30 million traces did not show statistically significant first- and second-order differences between trace sets with fixed and random inputs. The template-based DPA analysis, on the pseudo-random trace set for the profiling phase (15 million traces) and on a sub-set of 300k fix input traces for matching phase targeting the first-round S-box output, and template attack on ciphertext, did not indicate any potential information leakage.”
” The results for the soft IP presented in the report were obtained on the TOE which is the basic hardware implementation of the soft IP without additional levels of security (e.g. that are present in a secure silicon layout). Therefore the internal strength of the soft IP itself was evaluated. This indicates that the investigated features and parameters of the soft IP implementation should be robust against SCA and fault injection attacks in different implementations including ASIC. Nevertheless, according to the Common Criteria rules, the strength of the final composite product must be evaluated on its own.”
