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...
Randomness extractors are important tools in cryptography. Their goal is to compress a high-entropy source into a more uniform output. Beyond their theoretical interest, they have ...
We present an AES cipher implementation that is based on the BlockRAM and DSP units embedded within Xilinx’s Virtex-5 FPGAs. An iterative “basic” module outputs a 32 bit col...
This paper presents the results of applying an attack against the Data Encryption Standard (DES) implemented in some applications, using side-channel information based on CPU delay...
