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 ...
Please introduce links to this page from ; try the Find link tool for suggestions. ( August 2024 ) In cybersecurity, pixel stealing attacks are a group of timing side-channel attacks that allow cross-origin websites to infer how a particular pixel is displayed to the user.
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.
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.
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.
Cryptographic attacks that subvert or exploit weaknesses in this process are known as random number generator attacks. A high quality random number generation (RNG) process is almost always required for security, and lack of quality generally provides attack vulnerabilities and so leads to lack of security, even to complete compromise, in ...

Hardware security is a discipline originated from the cryptographic engineering and involves hardware design, access control, secure multi-party computation, secure key storage, ensuring code authenticity, measures to ensure that the supply chain that built the product is secure among other things.
