Constructing CCA-secure predicate encapsulation schemes from CPA-secure schemes and universal one-way hash functions
predicate key encapsulation mechanism chosen-ciphertext security

We present a new transformation of chosen-plaintext secure predicate encryption schemes
with public index into chosen-ciphertext secure schemes. Our construction requires only a universal
one-way ha...
Universal One-Way Hash Functions via Inaccessible Entropy
computational complexity cryptography hashing target collision-resistance onewayfunctions
2010/3/16
This paper revisits the construction of Universal One-Way Hash Functions (UOWHFs) from
any one-way function due to Rompel (STOC 1990). We give a simpler construction of UOWHFs,
which also obtains be...
Vortex: A New Family of One Way Hash Functions based on Rijndael Rounds and Carry-less Multiplication
One Way Hash Functions Rijndael Rounds Carry-less Multiplication

We present Vortex a new family of one way hash functions that can produce message
digests of 224, 256, 384 and 512 bits. The main idea behind the design of these hash
functions is that we use well k...
On Constructing Universal One-Way Hash Functions from Arbitrary One-Way Functions
One-Way Hash Functions Arbitrary One-Way Functions

A fundamental result in cryptography is that a digital signature scheme can be constructed
from an arbitrary one-way function. A proof of this somewhat surprising statement follows
from two results:...
