CWE-1300: Improper Protection of Physical Side Channels

Perform a set of leakage detection tests such as the procedure outlined in the Test Vector Leakage Assessment (TVLA) test requirements for AES [REF-1230]. TVLA is the basis for the ISO standard 17825 [REF-1229]. A separate methodology is provided by [REF-1228]. Note that sole reliance on this method might not yield expected results [REF-1239] [REF-1240].

Post-silicon, perform full side-channel attacks (penetration testing) covering as many known leakage models as possible against test code.

Pre-silicon - while the aforementioned TVLA methods can be performed post-silicon, models of device power consumption or other physical emanations can be built from information present at various stages of the hardware design process before fabrication. TVLA or known side-channel attacks can be applied to these simulated traces and countermeasures applied before tape-out. Academic research in this field includes [REF-1231] [REF-1232] [REF-1233].
