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...
This work presents a cryptographic analysis of AN.ON’s anonymization protocols. We have discovered three flaws of differing severity. The first is caused by the fact that the ...
—The increase in computational power of off-the-shelf hardware offers more and more advantageous tradeoffs among efficiency, cost and availability, thus enhancing the feasibil...

Very few public-key cryptosystems are known that can encrypt and decrypt in time b2+o(1) with conjectured security level 2b against conventional computers and quantum computers. Th...

In this paper we present a new practical key-recovery attack on the SFLASH signature scheme. SFLASH is a derivative of the older C∗ encryption and signature scheme that was broke...
