Triple Data Encryption Standard Encryption Engine: A Hardware Approach

A New Fast Data Encryption Algorithm (FDE)

Hardware Prototyping of an Efficient Encryption Engine

An approach to develop the FPGA of a flexible key RSA encryption engine that can be used as a standard device in the secured communication system is presented. The VHDL modeling of this RSA encryption engine has the unique characteristics of supporting multiple key sizes, thus can easily be fit into the systems that require different levels of security. A simple nested loop addition and subtrac...

A New Fast Data Encryption Algorithm (FDE)

Hardware Implementation of the Data Encryption Standard (DES)

This paper presents hardware implementation of the data encryption and decryption of the DES standard algorithm. The design consists of the S-Box circuit Exclusive-OR circuit, Circular Left Shift circuit and the control unit. The S-Box circuit implemented using 32 PLDs (Programmable Logic Device) chip that hold substitution a 48-bits input data and yields a 32-bits output data. The other circui...

Data Encryption Standard

In 1972, the NBS Institute for Computer Sciences and Technology (ICST) initiated a project in computer security, a subject then in its infancy. One of the first goals of the project was to develop a cryptographic algorithm standard that could be used to protect sensitive and valuable data during transmission and in storage. Prior to this NBS initiative, encryption had been largely the concern o...
