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.
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 ...
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 ...
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 ...
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.
One of the most effective ways to prevent electromagnetic attacks is to make it difficult for an attacker to collect an electromagnetic signal at the physical level. Broadly, the hardware designer could design the encryption hardware to reduce signal strength [ 25 ] or to protect the chip.
While a cyberweapon almost certainly results in either direct or indirect financial damages to the target group, direct financial gains for the sponsor are not a primary objective of this class of agent. Often cyberweapons are associated with causing physical or functional harm to the system which it attacks, despite being software. [2]
One could observe that the most effective way to mitigate a threat on the attack tree is to mitigate it as close to the root as possible. Although this is theoretically sound, it is not usually possible to simply mitigate a threat without other implications to the continued operation of the system.
