FLASHCARD QUESTION
Front
Which type of attack involves exploiting physical implementation of a system rather than weaknesses in its algorithms?
Back
Side-Channel Attack
Answer explanation
A side-channel attack exploits physical characteristics of a system, such as power consumption, timing, electromagnetic emissions, or acoustic signals, to extract sensitive information. Common types include:
Timing Attacks: Analyze execution time to deduce secret keys.
Power Analysis Attacks: Examine power usage patterns to infer cryptographic keys.
Electromagnetic Attacks: Capture emissions to gain data insights.
Cache Attacks: Exploit cache memory behavior to infer accessed data.
These attacks target the physical implementation rather than software vulnerabilities. Countermeasures include constant-time algorithms, power masking, and shielding.
