A Framework for UC-Secure Commitments from Publicly Computable Smooth Projective Hashing
UC commitment smooth projective hash function SPHF
2019/9/23
Hash proof systems or smooth projective hash functions (SPHFs) have been proposed by Cramer and Shoup (Eurocrypt'02) and can be seen as special type of zero-knowledge proof system for a language. Whil...
Isogeny-based hashing despite known endomorphisms
isogeny-based cryptography expander graphs hash functions
2019/8/19
The Charles-Goren-Lauter hash function on isogeny graphs of supersingular elliptic curves was shown to be insecure under collision attacks when the endomorphism ring of the starting curve is known. Si...
Current blockchains are restricted by the low throughput. Aimed at this problem, we propose Txilm, a protocol that compresses the size of transaction presentation in each block and thus saves the band...
Hashing modes are ways to convert a block cipher into a hash function, and those with AES as the underlying block cipher are referred to as AES hashing modes. Sasaki in 2011 introduced the first preim...
Fast and simple constant-time hashing to the BLS12-381 elliptic curve
hash functions elliptic curve cryptosystem implementation
2019/4/23
Pairing-friendly elliptic curves in the Barreto-Lynn-Scott family have experienced a resurgence in popularity due to their use in a number of real-world projects. One particular Barreto-Lynn-Scott cur...
Fine-Grained and Controlled Rewriting in Blockchains: Chameleon-Hashing Gone Attribute-Based
Chameleon-Hash Implementation Blockchain
2019/4/23
Blockchain technologies recently received a considerable amount of attention. While the initial focus was mainly on the use of blockchains in the context of cryptocurrencies such as Bitcoin, applicati...
Securing Update Propagation with Homomorphic Hashing
Homomorphic Hashing Folly open-source library
2019/3/4
In database replication, ensuring consistency when propagating updates is a challenging and extensively studied problem. However, the problem of securing update propagation against malicious adversari...
Oblivious transfer is an important tool against malicious cloud server providers. Halevi-Kalai OT, which is based on smooth projective hash(SPH), is a famous and the most efficient framework for 11-ou...
On Distributional Collision Resistant Hashing
Collision Resistant Hashing Distributional Hashing Multi-Collision Resistance
2018/5/28
Collision resistant hashing is a fundamental concept that is the basis for many of the important cryptographic primitives and protocols. Collision resistant hashing is a family of compressing function...
Founding Cryptography on Smooth Projective Hashing
oblivious transfer secure multiparty computation malicious adversaries
2018/5/16
Oblivious transfer (OT) is a fundamental primitive in cryptography. Halevi-Kalai OT (Halevi, S. and Y. Kalai (2012), Journal of Cryptology 25(1)), which is based on smooth projective hash(SPH), is a f...
An interesting consequence of our results is a potential new avenue for bypassing black-box separations. In particular, proving (with necessarily non-black-box techniques) that parallel repetition amp...
Worst-Case Hardness for LPN and Cryptographic Hashing via Code Smoothing
LPN Worst-Case to Average Case Reductions Collision-Resistant Hashing
2018/3/23
We present a worst case decoding problem whose hardness reduces to that of solving the Learning Parity with Noise (LPN) problem, in some parameter regime. Prior to this work, no worst case hardness re...
While there has been a lot of progress in designing efficient custom protocols for computing Private Set Intersection (PSI), there has been less research on using generic Multi-Party Computation (MPC)...
In the past few years billions of user passwords have been exposed to the threat of offline cracking attempts. Such brute-force cracking attempts are increasingly dangerous as password cracking hardwa...
Hashing solutions instead of generating problems: On the interactive certification of RSA moduli
RSA parameter validation zero-knowledge proofs
2018/1/12
Certain RSA-based protocols, for instance in the domain of group signatures, require a prover to convince a verifier that a set of RSA parameters is well-structured (e.g., that the modulus is the prod...
