Hints by Hertz

DFS leakage toolkit for Hertzbleed-style attacks on Kyber (CPA) and NTTRU (CCA).

Requirements

• Intel Core i7-9700, Ubuntu 20.04
• Root access for MSR reads
• Python 3 with matplotlib, numpy, pandas
• stress-ng, gcc, AVX2 support

Layout

Directory	Function
01-leakage-channel-data	Confirm DFS channel on your CPU
02-Kyber-NTT	NTT frequency & time measurements
03-Kyber-CPA-Uncompressed	CPA attack on Kyber AVX2
03-Kyber-KnownSK_*	Key pair verification
04-NTTRU	NTTRU run-near (driver/plot)
04-NTTRU-bak	Previous NTTRU code backup
05-ToyExample	Minimal end-to-end demo
06-Bit_Estimation	DDGR security-loss estimation

Quick Start

# 1. Calibrate leakage
cd 01-leakage-channel-data && sudo ./run-steady.sh

# 2. Measure NTT
cd 02-Kyber-NTT/freq && make && sudo ./run.sh

# 3. Run Kyber CPA attack (~12h)
cd 03-Kyber-CPA-Uncompressed/hint_pair_search && ./run.sh

# 4. Run NTTRU attack
cd 04-NTTRU && make && ./run_near_f_and_random_100_avx.sh

All scripts require sudo for MSR access. Use --help for options.
