Impossible Boomerang Attacks Revisited

IACR Transactions on Symmetric Cryptology
The impossible boomerang (IB) attack was first introduced by Lu in his doctoral thesis and subsequently published at DCC in 2011. The IB attack is a variant of the impossible differential (ID) attack by incorporating the idea of the boomerang attack. In

SCRAMBLE-CFI: Mitigating Fault-Induced Control-Flow Attacks on OpenTitan

, 2023
Secure elements physically exposed to adversaries are frequently targeted by fault attacks. These attacks can be utilized to hijack the control-flow of software allowing the attacker to bypass security measures, extract sensitive data, or gain full code ...

Finding the Impossible: Automated Search for Full Impossible-Differential, Zero-Correlation, and Integral Attacks [PDF]

, 2023
Impossible differential (ID), zero-correlation (ZC), and integral attacks are a family of important attacks on block ciphers. For example, the impossible differential attack was the first cryptanalytic attack on 7 rounds of AES.
