The Curse of Small Domains: New Attacks on Format-Preserving Encryption
Format-preserving encryption attacks
2018/6/5
Format-preserving encryption (FPE) produces ciphertexts which have the same format as the plaintexts. Building secure FPE is very challenging, and recent attacks (Bellare, Hoang, Tessaro, CCS '16; Dur...

Format-Preserving Encryption Feistel Networks Tweakable Encryption
2017/6/6
The National Institute of Standards and Technology (NIST) recently published a Format-Preserving Encryption standard accepting two Feistel structure based schemes called FF1 and FF3. Particularly, FF3...
Message-recovery attacks on Feistel-based Format Preserving Encryption
Format-preserving encryption attacks
2016/12/10
We give attacks on Feistel-based format-preserving encryption (FPE) schemes that succeed in message recovery (not merely distinguishing scheme outputs from random) when the message space is small. For...
