Optical and EM Fault-Attacks on CRT-based RSA: Concrete Results
Jörn-Marc Schmidt, Michael J. Hutter · 2007
RSA is a well-known algorithm that is used in various cryptographic systems like smart cards and e-commerce applications. This article presents practical attacks on implementations of RSA that use the Chinese Remainder Theorem (CRT). The attacks have been performed by inducing faults into a cryptographic device through optical and electromagnetic injections. We show optical attacks using fibre-optic light guides. Furthermore, we present a new non-invasive electromagnetic fault-attack using high-frequency spark gaps. All attacks have been performed using low-cost equipment.
