OBFUSCATION OF DSP CIRCUITS THROUGH HIGH LEVEL TRANSFORMATIONS

D. Naga Sudha

Abstract :

This paper gives an overall idea to design confounded circuits for digital signal processing applications by utilizing high level transformations, confounding finite state machine (FSM) depends on a key and reconfigurator. The intention is design of Digital signal processing circuits which may reused by the particular working techniques by originator. This design focused at high level transformations of repeated state graphs which have been utilized for speed, power compromises. The primary idea to evolve a design process to use high level transformations that not solely meet these tradeoffs however additionally change the architectures each structurally and functionally. Many modes of operations are introduced for obfuscation wherever the outputs are meaningful from an indication process point of view, however are functionally incorrect. Many meaningful modes are make use to reconfigure the filter order for various applications. Still existing modes may correspond with non meaningful modes. Functional obfuscation is fulfill by the right value key, and configures data. Incorrect input key is unsuccessful to change the reconfigurator and an incorrect configure data generates either a meaningful however non functional or non understandable mode. Here we have a liability to carry some chance of actuating the right mode, which ends up the decreased operations to confounded DSP circuit. The efficiency of proposed implementation is verified with IMAGE SCALING WITH INTERPOLATION AND DECIMATION design, strong high level obfuscation is proved and analyzed for various key sizes.
