Tamper Sensing Meshes in Payment Terminals and Beyond

본문 미리보기

Card Payment Terminals commonly use tamper sensing meshes to deter physical attacks on devices handling sensitive data such as cryptographic keys. Although their use of such meshes is frequently referenced in research literature, the public record contains little research on their construction. Addressing this gap, in this paper we present the first comprehensive analysis of the practical implementation of tamper sensing meshes across a wide range of payment terminals, and some other devices suc
