Simple SIMON: FPGA implementations of the SIMON 64/128 Block Cipher

In this paper we will present various hardware architecture designs for implementing the SIMON 64/128 block cipher as a cryptographic component offering encryption, decryption and self-contained key-scheduling capabilities and discuss the issues and design options we encountered and the tradeoffs we made in implementing them. Finally, we will present the results of our hardware architectures' implementation performances on the Xilinx Spartan-6 FPGA series.Comment: 20 page

Analysis of the effects of higher bits-per-cell iris recognition

In this paper, a modification of the iris recognition approach by Daugman (2004) is presented. Traditionally, each cell in an iris template consists of a matrix of two-bit values, extracted from a normalized iris image. An existing iris recognition system was modified, in order to allow for extraction of an arbitrary amount of bits per cell. This paper explains how the original iris recognition system works and how it was modified. Also, a statistical analysis of the impact on recognition quality is presented, which turned out to be limited

Sponges and Engines: An introduction to Keccak and Keyak

In this document we present an introductory overview of the algorithms and design components underlying the Keccac cryptographic primitive and the Keyak encryption scheme for authenticated (session-supporting) encryption. This document aims to familiarize readers with the basic principles of authenticated encryption, the Sponge and Duplex constructions (full-state, keyed as well as regular versions), the permutation functions underlying Keccak and Keyak as well as Keyak v2\u27s Motorist mode of operation
