What is power side-channel attack?
In cryptography, a side channel attack is used to extract secret data from some secure device (such as a smart card, tamper-resistant “black box”, or integrated circuit). Power analysis is a form of side channel attack in which the attacker studies the power consumption of a cryptographic hardware device.
What is a side channel pump?
Side channel pumps share the characteristics of both positive displacement pumps and centrifugal pumps. In side channel pumps the power of a star-shaped impeller (e. g. star impeller) rotating concentrically in a casing is transferred to the fluid handled in a side channel arranged next to the impeller.
What is a channel pump?
A side channel pump, also known as liquid ring pump is a type of self-priming multistage pump, having characteristics of that of a positive displacement pump. Side Channel pumps are quite unique in terms that they can handle up to 50% of entrained gas with fluid and vapour taking different paths through the pump.
What is the purpose of a side channel attack?
Side-channel attacks are attempts to uncover secret information based on physical property (e.g., power consumption or EM radiation) of a cryptosystem, rather than exploiting the theoretical weaknesses in the implemented cryptographic algorithm.
Are there any side channel attacks in smart grid?
Except for smart metering, where e.g. by the German BSI the usage of secure processors is enforced ( BSI, 2014 ), field devices in the smart grid usually come with little security functionality. Therefore, side-channel attacks might be considered less relevant compared to the simple attack methods presented above.
How are side channels used in cryptographic algorithms?
In this chapter, we focus on different side-channel attack modalities in hardware implementations of cryptographic algorithms. Chapter 16, on the other hand, covers side-channels in a processor micro-architecture, which can be controlled by a software, and are visible through it.
Which is an example of a power monitoring attack?
Power-monitoring attack — attacks that make use of varying power consumption by the hardware during computation. Electromagnetic attack — attacks based on leaked electromagnetic radiation, which can directly provide plaintexts and other information.
