HPolyC: length-preserving encryption for entry-level processors
SPRP VIL tweakable encryption
2018/8/6
We present HPolyC, a construction which builds on Poly1305, XChaCha12, and a single block cipher invocation per message to offer length-preserving encryption with a fast constant-time implementation w...
Faster Privacy-Preserving Location Proximity Schemes
Location Privacy Proximity Secure Computation
2018/7/20
In the last decade, location information became easily obtainable using off-the-shelf mobile devices. This gave a momentum to developing Location Based Services (LBSs) such as location proximity detec...

2018/7/17
Deep learning technology has been evaluated to achieve the high-accuracy of state-of-the-art algorithms in a variety of AI tasks. Its popularity draws security researchers’ attention to the topic of p...
Lower Bounds on Structure-Preserving Signatures for Bilateral Messages
Structure-Preserving Signatures Bilateral Messages Crucial Relation
2018/7/9
Lower bounds for structure-preserving signature (SPS) schemes based on non-interactive assumptions have only been established in the case of unilateral messages, i.e. schemes signing tuples of group e...
Privacy Preserving Verifiable Key Directories
Verifiable key directory Zero knowledge sets Accumulators
2018/6/19
In recent years, some of the most popular online chat services such as iMessage and WhatsApp have deployed end-to-end encryption to mitigate some of the privacy risks to the transmitted messages. But ...
Ciphertext Expansion in Limited-Leakage Order-Preserving Encryption: A Tight Computational Lower Bound
Encrypting plaintexts CRYPTO
2018/6/5
Order-preserving encryption emerged as a key ingredient underlying the security of practical database management systems. Boldyreva et al. (EUROCRYPT '09) initiated the study of its security by introd...
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...
