Key Points
- Side channel attacks, such as power analysis, can extract secret keys from smart cards and other devices by analyzing the flickering of LEDs on their power circuits.
- Power analysis attacks have been common in the past and are difficult to stop when implementing cryptographic algorithms.
- Power analysis attacks can exploit the variations in power consumption during cryptographic operations to determine secret bits of a key.
- Implementations of cryptographic algorithms need to be carefully designed to prevent vulnerabilities to power analysis attacks.
- The intensity of LEDs on devices can change as the power consumption of the CPU changes, providing potential clues about secret keys.
- The rolling shutter effect on a camera can be used to increase the frame rate and capture the slight variations in LED intensity caused by cryptographic operations.
- Power analysis attacks can be conducted remotely using cameras, making them potentially less secure than physical attacks.
- Power analysis attacks have been demonstrated on different cryptographic algorithms, including elliptic curve DSA and super singular isogeny key exchange.

A recent paper has gained attention on social media for its concept of extracting secret keys from smart cards and devices by analyzing the flickering of LEDs on their power circuits. This idea may seem ridiculous, but it is actually a type of side channel attack known
In a previous video, the speaker discussed the use of the square always mod concept to ensure constant time in cryptographic operations. This eliminates the issue of varying power consumption based on the key bits. The paper being discussed introduces two variants of this concept, one
The camera used in this attack captures images by scanning down rows, resulting in a delay between rows. This delay causes the LED being filmed to appear slightly dimmer or brighter as the camera moves across the rows. By analyzing the changes in brightness, it
