Sårbarheter och hotanalys från sidokanaler med maskininlärning i fokus
Under det senaste decenniet har cyberattacker flyttat från att existera högt upp i programvarustacken till att även appliceras på den underliggande fysiska implementeringen. Trots det växande erkännandet av problemet finns det inga allmänna lösningar för att säkra de fysiska enheter som för närvarande är i användning.
