Security Arguments for Digital Signatures and Blind Signatures
Abstract. Since the appearance of public-key cryptography in the seminal DiffieHellman paper, many new schemes have been proposed and many have been broken. Thus, the simple fact t...

A New Public-Key Cryptosystem over a Quadratic Order with Quadratic Decryption Time
We present a new cryptosystem based on ideal arithmetic in quadratic orders. The method of our trapdoor is different from the Diffie

A Detailed Analysis of SAFER K
In this paper we analyze the block cipher SAFER K. First, we show a weakness in the key schedule, that has the effect that for almost every key there exists on the average three an...

Player Simulation and General Adversary Structures in Perfect Multiparty Computation
The goal of secure multiparty computation is to transform a given protocol involving a trusted party into a protocol without need for the trusted party, by simulating the party am...
