Introduction: secured co-processors for machine learning and DSP applications using biometrics

The chapter gives an introduction on security requirements of co-processors for machine learning (ML) and digital signal processing (DSP) applications and the role of biometrics in securing them. This introduction of the book tries to build interest in readers about the various DSP and ML co-processors; behavioral synthesis design process for generating secured DSP and ML co-processors and importance of biometric security for hardware authentication.The chapter is organized as follows: Section 1.1 introduces about the co-processors, different hardware threats, and conventional security solutions; Section 1.2 highlights the significance of behavioral synthesis in designing and securing co-processors; Section 1.3 introduces about the co-processors for ML applications, why ML co-processors need to be secured, and how behavioral synthesis plays a crucial role in securing ML co-processors; Section 1.4 introduces about the behavioral synthesis perspective in designing and securing DSP co-processors; Section 1.5 introduces about the biometric security based on fingerprint, face, and palmprint for ML and DSP co-processors.
