Title : Secured Microchip Design to Countermeasure against Physical Hardware Attack

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. In this talk, we shall provide an overview of the different cryptography algorithms. We will also present the side channel attacks, in particular the powerful Correlation Power Analysis (CPA) and Correlation Electromagnetic Analysis (CEMA) with a leakage model can be used to reveal the secret keys of the cryptosystems. Several of the current-art attack techniques will be shared in this talk. Two main approaches of countermeasure against CPA and CEMA attacks, i.e. Hiding and Masking, which usually known as hardware approach and algorithmic (DSP) approach will also be discussed in this talk. We will also present several effective countermeasure techniques based on these approaches to design a highly secured microchip.
