Side-channel attacks are relatively easy and inexpensive to mount against cryptographically protected devices but are especially difficult to defend against. In this paper, we consider DEMA attacks on contactless smart card systems, to name a few:
-
physical access control (smart locks and key cards)
-
payment cards
-
transportation passes
-
digital passports
-
chip IDs
Hackers have found ways of breaking into smart cards, stealing money and services and gaining unauthorized access. A new approach to protecting smart cards against DEMA attacks is described, allowing manufacturers to cut protection costs and save time during development.
