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...
Programmable Hash Functions from Lattices: Short Signatures and IBEs with Small Key Sizes
public-key cryptography PHF
2016/5/30
Driven by the open problem raised by Hofheinz and Kiltz (Journal of Cryptology, 2012), we study the formalization of lattice-based programmable hash function (PHF), and give two types of constructions...
Programmable Hash Functions go Private:Constructions and Applications to (Homomorphic) Signatures with Shorter Public Keys
Public-Key Cryptography Programmable Hash Functions Digital Signatures
2015/12/23
We introduce the notion of asymmetric programmable hash functions (APHFs, for short),
which adapts Programmable Hash Functions, introduced by Hofheinz and Kiltz at Crypto 2008, with
two main differe...
Programmable Hash Functions in the Multilinear Setting
programmable hash functions multilinear maps
2014/3/12
We adapt the concept of a programmable hash function (PHF, Crypto 2008) to a setting in which a multilinear map is available. This enables new PHFs with previously unachieved parameters.
To demonstra...

We introduce a new combinatorial primitive called *programmable hash functions* (PHFs). PHFs can be used to *program* the output of a hash function such that it contains solved or unsolved discrete lo...
