Low Cost Attacks on Smart Cards The Electromagnetic Side-Channel
نویسنده
چکیده
This paper documents a successful Electromagnetic Analysis attack implemented using limited technical knowledge and low cost equipment. EM traces were acquired from a sample card and analysis software successfully identified the correct key guesses in proprietary traces. It is important to note that although this attack was implemented on a smart card running the DES encryption algorithm, that the same kind of attack is possible on other cards, as long as the implementation details of the algorithm are known.

One-Trial Electromagnetic Attack on Modular Exponentiation
Correlative side-channel attack based on ensembles of test sequences is developed. For conducted and radiated electromagnetic analysis the maximal eavesdrop distance is estimated. By a low-cost measurement system developed for noninvasive monitoring of smart cards power consumption an attack on modular exponentiation, based on one power trace only, is realized.

Smart cards are small, portable, tamper-resistant computers used in securitysensitive applications ranging from identi_cation and access control to payment systems. Side-channel attacks, which use clues from timing, power consumption, or even electromagnetic (EM) signals, can compromise the security of these devices and have been an active research area since 1996. Newer contactless” cards comm...

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-...
