Abstract
Abstract. Every practical implementation of a cryptographic algorithm represents a physical device possessing potential side channels not covered by the security models of theoretical cryptography. Hence, even provable secure cryptographic algorithms may be attacked due to leakage of information. Smart cards and security ICs are often used as tamper-proof security devices. To prevent an attacker from exploiting easily accessible information like power consumption, running time, input-output behavior under malfunctions caused, i. e., by irregular clocking, radiation, power peaks, special precautions have to be taken. Commonly used countermeasures against information leakage are the reduction of the signal-to-noise ratio using special implementation techniques for hardware and software and the decorrelation of secret internal data from the channels observable by an attacker. In this contribution we survey the basic concepts of known attacks based on information leakage, i. e., timing attack, differential fault analysis, SPA, and DPA, and the countermeasures proposed in the literature. These methods comprise hardware design techniques and the design and implementation of modifications of cryptographic algorithms. 1
