Side Channels Attack

Question 1

What are the 4 passive attacks?

Answer 1

Timing
Power Consumption Analysis
Electro-Magnetic (EM) Radiation
Sound, Temperature

Question 2

What are 4 invasive attacks?

Answer 2

Microprobing
Circuit Modification
Photonic Emissions

Effective but expensive

Question 3

What is a side channel attack?

Answer 3

A side-channel attack is any attack based on information
gained from the physical implementation of a system /
process

Question 4

What is power consumption analysis?

Answer 4

Exploit the fact that (dynamic) power consumption of
chip is correlated to operations and/or intermediate
results of the algorithm.

Two main forms: Simple & Differential

Question 5

What is the requirement for power consumption analysis?

Answer 5

They require you to be very knowledgeable in the system that is being attacked.

Question 6

What is a timing analysis attack?

Answer 6

Learn the system’s secret by observing how long

it takes to perform various computations.
