What is a side-channel attack example?

Side-channel attacks (SCAs) aim at extracting secrets from a chip or a system, through measurement and analysis of physical parameters. Examples of such parameters include supply current, execution time, and electromagnetic emission.

What are the four types of side channel attacks?

Types of side-channel attacks

• Electromagnetic. An attacker measures the electromagnetic radiation, or radio waves, given off by a target device to reconstruct the internal signals of that device.
• Acoustic. The attacker measures the sounds produced by a device.
• Power.
• Optical.
• Timing.
• Memory cache.
• Hardware weaknesses.

Which of the following attacks uses side channel?

Other well-known side channel attacks include spying on the power consumption of an electronic device to steal an encryption key, or acoustic attacks that record the sound of a user’s key strokes to steal their passphrase. These side channel attacks are not theoretical and have been known about for decades.

Which attack uses side channel analysis?

Such measurements can be used to infer cryptographic keys using techniques equivalent to those in power analysis or can be used in non-cryptographic attacks, e.g. TEMPEST (aka van Eck phreaking or radiation monitoring) attacks.

What is the definition of a side channel attack?

What is a side-channel attack? A side-channel attack is a security exploit that aims to gather information from or influence the program execution of a system by measuring or exploiting indirect effects of the system or its hardware — rather than targeting the program or its code directly.

Can a side channel attack be launched against Linux?

Side-channel attacks can be launched against any operating system, including Windows and Linux. Side-channel attacks work by monitoring the emissions produced by electronic circuits when the victim’s computer is being used.

Why are side channel analysis techniques of concern?

Side channel analysis techniques are of concern because the attacks can be mounted quickly and can sometimes be implemented using readily available hardware costing from only a few hundred dollars to thousands of dollars.

How does a side channel attack break cryptography?

Enter side channel attacks. A side channel attack breaks cryptography by using information leaked by cryptography, such as monitoring the electromagnetic field (EMF) radiation emitted by a computer screen to view information before it’s encrypted in a van Eck phreaking attack, aka Transient Electromagnetic Pulse Emanation STandard (TEMPEST).
