Side-channel analysis (SCA) of PIN comparison
Dilaporkan pada October 31, 2018
Using a SCA bench an attacker could create the database of power consumption and electromagnetic traces of a device. This database could later be used to unlock a locked device using the same SCA bench. The issue was fixed by rewriting the device storage to not compare PINs directly, but rather compare random data stretched by the PIN.
Fixed in firmware 1.8.0.
