Smooth Projective Hashing and Password-Based Authenticated Key Exchange from Lattices
Abstract. We describe a public-key encryption scheme based on lattices — specifically, based on the hardness of the learning with error (LWE) problem — that is secure against ...

A Framework for Universally Composable Non-committing Blind Signatures
A universally composable (UC) blind signature functionality requres users to commit to the message to be blindly signed. It is thereby impossible to realize in the plain model. Th...

Security Notions and Generic Constructions for Client Puzzles
Computational puzzles are mildly difficult computational problems that require resources (processor cycles, memory, or both) to solve. Puzzles have found a variety of uses in secu...

Foundations of Non-malleable Hash and One-Way Functions
Non-malleability is an interesting and useful property which ensures that a cryptographic protocol preserves the independence of the underlying values: given for example an encryp...

Secure Multi-party Computation Minimizing Online Rounds
Multi-party secure computations are general important procedures to compute any function while keeping the security of private inputs. In this work we ask whether preprocessing can...

Cryptanalysis of CTC2
CTC is a toy cipher designed in order to assess the strength of algebraic attacks. While the structure of CTC is deliberately weak with respect to algebraic attacks, it was claimed...

Square, a New Multivariate Encryption Scheme
We propose and analyze a multivariate encryption scheme that uses odd characteristic and an embedding in its construction. This system has a very simple core map F(X) = X2 , allowi...
