Silicon Labs SixG301xxx Devices SYMCRYPTO Engine DPA Countermeasure Vulnerability

A vulnerability exists in the SYMCRYPTO engine on SixG301xxx devices, where countermeasures against Differential Power Analysis (DPA) are not adequately random, leading to potential repetition. This issue will affect KSU keys that utilize SYMCRYPTO.

Impact

The vulnerability could compromise the effectiveness of DPA countermeasures, potentially allowing for DPA attacks to be more successful or easier to conduct.
