This thesis presents a novel approach to design confounded circuits for digital signal processing applications using high level transformations, a key based confounding finite-state machine (FSM), and a reconfiguration. The aim is to design Digital Signal Processing circuits which are reutilized by the specific operational methods by the designer. This design aims at the high-level transformations of repeated state graphs which have been utilized for area, speed, power compromises. It is the primary idea to develop a design flow 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. Examples of such methods incorporates the next order digital filter primarily based applications that are executed in an exceedingly time multiplexed fashion. Many meaningful modes are make use to reconfigure the filter order for various applications. Still existing modes may correspond with non meaningful modes. The configure data controls varied modes of the circuit operation. 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 perform some chance of activating the right mode, which ends up the reduced operations to an obfuscated DSP circuit. The efficiency of proposed implementation is verified with IMAGE SCALLING WITH INTERPOLATION AND DECIMATION design, strong high level obfuscation is proved and analyzed for various key sizes.
