Protecting Smart Cards from Power Analysis Attacks

Abstract — As the demand on smart cards is increasing nowadays, a whole family of attacks are also present and can be a real threat on this technology future unless a solution can be implemented to safeguard it. In this paper I am presenting a new technique to protect smart cards from two main attacks, Differential Power Analysis (DPA) and Simple Power Analysis (SPA) Attacks. The two attacks allows the attacker to gain enough knowledge to know the secret key of the card’s user. I
