IISFA: Ineffective Instruction-Skip Fault Attacks on Bitslice Implementations↗ (원문, 새 창)

본문 미리보기

Redundancy countermeasures prevent differential fault analysis by withholding faulty ciphertexts. Ineffective fault analysis and statistical ineffective fault attacks exploit executions in which an injected fault leaves the result unchanged, using constraints on intermediate values or statistical bias to recover keys. In this paper, we present an Ineffective Instruction-Skip Fault Attack (IISFA) on bitsliced implementations protected by redundancy. A bitsliced instruction processes $m$ S-boxes s
