Remote Timing Attacks are Practical

by David Brumley, Dan Boneh
"... Timing attacks are usually used to attack weak computing devices such as smartcards. We show that timing attacks apply to general software systems. Specifically, we devise a timing attack against OpenSSL. Our experiments show that we can extract private keys from an OpenSSL-based web server running ..."

Timing Attacks on Implementations of Diffie-Hellman, RSA, DSS, and Other Systems

by Paul C. Kocher , 1996
"... By carefully measuring the amount of time required to perform private key operations, attackers may be able to find fixed Diffie-Hellman exponents, factor RSA keys, and break other cryptosystems. Against a vulnerable system, the attack is computationally inexpensive and often requires only known cip ..."

Cache-timing attacks on AES

by Daniel J. Bernstein , 2005
"... Abstract. This paper warns against the use of S-boxes in cryptography. In particular, this paper shows that a simple cache-timing attack against AES software reveals some key bits; this paper also discusses some of the obstacles to constant-time array access on modern CPUs. ..."

Timing Attacks on Web Privacy

by Edward W. Felten, Michael A. Schneider , 2000
"... We describe a class of attacks that can compromise the privacy of users' Web-browsing histories. The attacks allow a malicious Web site to determine whether or not the user has recently visited some other, unrelated Web page. The malicious page can determine this information by measuring the ti ..."

A report on Timing Attacks

by Vasileios Lampos , Stavros Syrimis , Christos Tsiotras , 2007
"... A side channel attack tries to exploit specific properties of the implementation and operating environment of a cryptosystem rather than its mathematical specification [HMV04]. Timing attack is a class of side channel attack where the attacker tries to break an encryption algorithm by using informat ..."

A Practical Implementation of the Timing Attack

by J. -f. Dhem, F. Koeune, P.-A. Leroux, P. Mestré, J.-J. Quisquater, J. -l. Willems , 1998
"... When the running time of a cryptographic algorithm is nonconstant, timing measurements can leak information about the secret key. This idea, first publicly introduced by Kocher, is developed here to attack an earlier version of the CASCADE smart card. We propose several improvements on Kocher's ..."
