Implementation of IDEA NXT on FPGA
Abstract
Data security is considered as prime importance in various fields, to accomplish this security cryptographic algorithms are used. Cryptography is a means scribbling information for security reason, so that it is not obtainable to intruders. IDEA NXT is upcoming cryptographic algorithms which belong to a symmetric block cipher family. IDEA NXT is an inheritor of IDEA (International Data Encryption Algorithm) cryptographic algorithm. IDEA NXT uses Lai-Massey structure, an OR function which is known as orthomorphism and number of rounds. IDEA NXT can be simply implemented on hardware or software platform. In this paper we have implemented IDEA NXT on Spartan3E FPGA. Implementation of IDEA NXT algorithm on Spartan3E is physically secure as it cannot be modified or read from exterior and parallel operation increase the speed of execution. We have implemented the IDEA NXT algorithm and reduced the static power from 0.082 W to 0.071 W.
