Name

C4: leaky power

Type

Cryptology

Description

C4 is a very advanced AES based defensive system. You are able to monitor the power lines. Is that enough?

You’re given three files:

• powertraces.npy: Measurements (over time) of power consumption of a chip while performing AES encryption
• plaintexts.npy: Corresponding plaintext inputs that were encrypted
• instructions.jwe: File encrypted using the same key as plaintexts.npy.

note: The first two files are NumPy arrays.
