Title: Hardware Attack and Assurance with Machine Learning: A Security Threat to Circuits and Systems

Abstract: Banking, defence applications and cryptosystems often demand security features, including cryptography, tamper resistance, stealth, and etc., by means of hardware approaches and/or software approaches to prevent data leakages. The hardware physical attacks or commonly known as side channel attacks have been employed to extract the secret keys of the encrypted algorithms implemented in hardware devices by analyzing their physical parameters such as power dissipation, electromagnetic interference and timing information. Altered functions or unauthorized modules may be added to the circuit design during the shipping and manufacturing process, bringing in security threats to the deployed systems. In this presentation, we will discuss hardware assurance from both device level and circuit level, and present how machine learning techniques can be utilized. At the device level, we will first provide an overview of the different cryptography algorithms and present the side channel attacks, particularly the powerful Correlation Power Analysis (CPA) and Correlation Electromagnetic Analysis (CEMA) with a leakage model that can be used to reveal the secret keys of the cryptosystems. We will then discuss several countermeasure techniques and present how highly secured microchips can be designed based on these techniques. At the circuit level, we will provide an overview of manufactured IC circuit analysis through invasive IC delayering and imaging. We then present several machine learning techniques that can be efficiently applied to the retrieval of circuit contact points and connections for further netlist/functional analysis.
