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...
Identity-Based Format-Preserving Encryption
identity-based cryptography format-preserving encryption tweakable blockcipher
2017/9/14
We introduce identity-based format-preserving encryption (IB-FPE) as a way to localize and limit the damage to format-preserving encryption (FPE) from key exposure. We give definitions, relations betw...
Breaking the FF3 Format-Preserving Encryption Standard Over Small Domains
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...
In the encryption of credit-card data as well as other applications, we may want to encipher
in such a way that a certain property of the plaintext is preserved in the ciphertext. This paper
