It is broadly an attack in which the attacker is given a black box containing either an instance of the system under attack with an unknown key, or a random object in the domain that the system aims to emulate, then if the algorithm is able to tell whether the system or the random object is in the black box, one has an attack.
Open key model attacks - where the attacker has some knowledge about the key for the cipher being attacked. [ 5 ] Related-key attack - in this attack the cryptanalyst has access to ciphertext encrypted from the same plaintext using other (unknown) keys which are related to the target key in some mathematically defined way.
Acoustic cryptanalysis is a type of side channel attack that exploits sounds emitted by computers or other devices.. Most of the modern acoustic cryptanalysis focuses on the sounds produced by computer keyboards and internal computer components, but historically it has also been applied to impact printers, and electromechanical deciphering machines.
A number of techniques have been proposed to subvert attacks based on return-oriented programming. [17] Most rely on randomizing the location of program and library code, so that an attacker cannot accurately predict the location of instructions that might be useful in gadgets and therefore cannot mount a successful return-oriented programming ...
The graph on the left denotes a case where the timing attack is successfully able to detect a cached image whereas the one on the right is unable to do the same. 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 ...
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 ...
By Raphael Satter. WASHINGTON (Reuters) -The U.S. government is warning state governors that foreign hackers are carrying out disruptive cyberattacks against water and sewage systems throughout ...
Cache attack — attacks based on attacker's ability to monitor cache accesses made by the victim in a shared physical system as in virtualized environment or a type of cloud service. Timing attack — attacks based on measuring how much time various computations (such as, say, comparing an attacker's given password with the victim's unknown ...
