In cryptography, a timing attack is a side-channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms. Every logical operation in a computer takes time to execute, and the time can differ based on the input; with precise measurements of the time for each operation ...

Cache timing attacks also known as Cache attacks are a type of side-channel attack that allows attackers to gain information about a system purely by tracking cache access made by the victim system in a shared environment.
Timing information, power consumption, electromagnetic leaks, and sound are examples of extra information which could be exploited to facilitate side-channel attacks. Some side-channel attacks require technical knowledge of the internal operation of the system, although others such as differential power analysis are effective as black-box attacks.
In 2002 and 2003, Yukiyasu Tsunoo and colleagues from NEC showed how to attack MISTY and DES symmetric key ciphers, respectively. In 2005, Daniel Bernstein from the University of Illinois, Chicago reported an extraction of an OpenSSL AES key via a cache timing attack, and Colin Percival had a working attack on the OpenSSL RSA key using the Intel processor's cache.
This section was confusing. While the example applied to OpenSSL, the attack was general to SSL/TLS using block ciphers in CBC mode (which itself might be a good example). I think the article requires more background to timing attacks, and then include more detailed examples if needed. Mmernex 15:17, 16 March 2009 (UTC)

Cache-timing attacks rely on the ability to infer hits and misses in shared caches on the web platform. [54] One of the first instances of a cache-timing attack involved the making of a cross-origin request to a page and then probing for the existence of the resources loaded by the request in the shared HTTP and the DNS cache.
