FPGA Based Cipher Design & Implementation of Recursive Oriented Block Arithmetic and Substitution Technique (ROBAST)

FPGA Based Cipher Design & Implementation of Recursive Oriented Block Arithmetic and Substitution Technique (ROBAST).docx

Proposed FPGA based technique considers a message as a binary string on which ROBAST is applied. A block of n-bits is taken as an input stream, where n ranges from 8 to 256 – bit, then ROBAST is applied in each block to generate intermediate stream, any one intermediate stream is considered as a cipher text. The same operation is performed repeatedly on various block sizes. It is a kind of bloc...

Efficient FPGA Implementation of Block Cipher MISTY1

NESSIE is a 3-year research project (2000-2002). The goal of the project is to put forward some algorithms to obtain a set of the next generation of cryptographic primitives. In order to achieve this objective, the project needs to evaluate mathematical security levels and software/hardware implementations. This paper investigates the significance of an FPGA implementation of the block cipher M...

A Dynamic FPGA Implementation of the Serpent Block Cipher

A JBits implementation of the Serpent block cipher in a Xilinx FPGA is described. JBits provides a Java-based Application Programming Interface (API) for the run-time modification of the configuration bitstream. This allows dynamic circuit specialization based on a specific key and mode (encrypt or decrypt). Subkeys are computed in software and treated as constants in the Serpent datapath. The ...
