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...
