Analysis of Covert Hardware Attacks
Samer Moein,Fayez Gebali,Issa Traore 한국정보기술융합학회 2014 JoC Vol.5 No.3
Current embedded system, such as cell phones and smart-cards, in corporate security devices or cryptographic processor. These cryptographic devices often store private keys or other sensitive data, so compromise of this data or the underlying hardware may lead to loss of privacy, forged access, or monetary theft. Even if the attackers fail to gain the secret information that is stored in a hardware, they may be able to disrupt the hardware or deny service leading to other kinds of security failures in the system. Therefore hardware attacks targets this security devices. Hardware attacks could be covert or overt based on awareness of the targeted system. This paper reviews proposed Accessibility/Resources/Time (ART) schema that quantifies hardware attacks. We focus in this paper on presenting covert attacks and quantify the attack using the ART schema.
