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 ...
Exploiting a TOCTOU race condition requires precise timing to ensure that the attacker's operations interleave properly with the victim's. In the example above, the attacker must execute the symlink system call precisely between the access and open. For the most general attack, the attacker must be scheduled for execution after 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.
One of the earliest known instances of a pixel-stealing attack was described by Paul Stone in a white paper presented at the Black Hat Briefings conference in 2013. [6] Stone's approach exploited a quirk in how browsers rendered images encoded in the SVG format.
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.
Trump made a series of misleading claims on topics ranging from Jan. 6 to terrorism to taxes at the first 2024 presidential debate, while Biden flubbed some facts.
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)
