Abstract. Since Crypto 2004, hash functions have been the target of many attacks which showed that several well-known functions such as SHA-0 or MD5 can no longer be considered sec...
Abstract. Field-Programmable Gate Arrays (FPGAs) have lately become a popular target for implementing cryptographic block ciphers, as a well-designed FPGA solution can combine some...
Abstract. In this paper, we study the soundness amplification by repetition of cryptographic protocols. As a tool, we use the Chernoff Information. We specify the number of attempt...
Abstract. Modes of operation adapt block ciphers to many applications. Among the encryption modes, only CFB Cipher Feedback has both of the following properties: Firstly it allow...

A method for extracting cryptographic key material from DRAM used in modern computers has been recently proposed in [9]; the technique was called Cold Boot attacks. When considerin...
