Information-Theoretic Key Agreement: From Weak to Strong Secrecy for Free
One of the basic problems in cryptography is the generation of a common secret key between two parties, for instance in order to communicate privately. In this paper we consider in...

The Sum of PRPs Is a Secure PRF
Given d independent pseudorandom permutations (PRPs) i, . . . , d over {0, 1}n , it appears natural to define a pseudorandom function (PRF) by adding (or XORing) the permutation re...

Analysis and Optimization of the TWINKLE Factoring Device
We describe an enhanced version of the TWINKLE factoring device and analyse to what extent it can be expected to speed up the sieving step of the Quadratic Sieve and Number Field S...

One-Way Trapdoor Permutations Are Sufficient for Non-trivial Single-Server Private Information Retrieval
We show that general one-way trapdoor permutations are sufficient to privately retrieve an entry from a database of size n with total communication complexity strictly less than n....

Efficient Receipt-Free Voting Based on Homomorphic Encryption
Voting schemes that provide receipt-freeness prevent voters from proving their cast vote, and hence thwart vote-buying and coercion. We analyze the security of the multi-authority ...

A NICE Cryptanalysis
We present a chosen-ciphertext attack against both NICE cryptosystems. These two cryptosystems are based on computations in the class group of non-maximal imaginary orders. More pr...

Cryptanalysis of Countermeasures Proposed for Repairing ISO 9796-1
Abstract. ISO 9796-1, published in 1991, was the first standard specifying a digital signature scheme with message recovery. In [4], Coron, Naccache and Stern described an attack o...
