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...

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...

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:...
