Deterministic Identity-Based Encryption from Lattice-Based Programmable Hash Functions with High Min-Entropy
deterministic identity-based encryption adaptively secure auxiliary-input
2019/1/26
There only exists one deterministic identity-based encryption (DIBE) scheme which is adaptively secure in the auxiliary-input setting, under the learning with errors (LWE) assumption. However, the mas...
Function Private Predicate Encryption for Low Min-Entropy Predicates
public-key cryptography ZIPE
2019/1/4
In this work, we propose new predicate encryption schemes for zero inner-product encryption (ZIPE) and non-zero inner-product encryption (NIPE) predicates from prime-order bilinear pairings, which are...
Non-Malleable Condensers for Arbitrary Min-Entropy, and Almost Optimal Protocols for Privacy Amplification
privacy amplification non-malleable extractor
2016/1/5
Recently, the problem of privacy amplification with an active adversary has received a lot of attention. Given a shared n-bit weak random source X with min-entropy k and a security parameter s, the ma...
Predictive Models for Min-Entropy Estimation
Entropy estimation Min-entropy Random number generation
2015/12/29
Random numbers are essential for cryptography. In most
real-world systems, these values come from a cryptographic pseudorandom
number generator (PRNG), which in turn is seeded by an entropy
source....
