METHOD AND APPARTUS FOR DIFFERENTIAL FAULT ATTACK

摘要

Disclosed are a method and apparatus for an error injection attack based on a random word error model to which an algebraic expression of modulo addition is applied. An error injection attack method according to an embodiment includes injecting an error into the last previous round and the last round of LEA (Lightweight Encryption Algorithm), performing an analysis on the modulo addition in which the error is propagated, and the analysis result It may include the step of obtaining a secret key based on the.
