Because side-channel attacks rely on the relationship between information emitted (leaked) through a side channel and the secret data, countermeasures fall into two main categories: (1) eliminate or reduce the release of such information and (2) eliminate the relationship between the leaked information and the secret data, that is, make the leaked information unrelated, or rather uncorrelated ...
In cryptography, electromagnetic attacks are side-channel attacks performed by measuring the electromagnetic radiation emitted from a device and performing signal analysis on it. These attacks are a more specific type of what is sometimes referred to as Van Eck phreaking , with the intention to capture encryption keys.
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 tailored access battery is a special laptop battery with Van Eck Phreaking electronics and power-side band encryption cracking electronics built into its casing, in combination with a remote transceiver. This allows for quick installation and removal of a spying device by simply swapping the battery. [10]
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 ...
In 2018, a class of side-channel attack was introduced at ACM and Black Hat by Eurecom's researchers: "Screaming Channels". [32] This kind of attack targets mixed-signal chips — containing an analog and digital circuit on the same silicon die — with a radio transmitter.
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
[1] [2] [16]: 12 The design team states that while designing Speck, they found differential attacks to be the limiting attacks, i.e. the type of attack that makes it through the most rounds; they then set the number of rounds to leave a security margin similar to AES-128's at approximately 30%.
