kem-07 BRQC — performance on AArch64 (system arm_1)
Independent measurement following the structure of the NICCS ARM self-assessment guide, §3.5 (1)–(7). Not a submitter self-assessment.
1. Basic information
- Category: public-key algorithm; function: key encapsulation
- Algorithm: BRQC
- Implementation versions measured: reference
- Parameter sets:
BRQC-128,BRQC-256,BRQC-512 - Security evaluation: kem-07 report
- Measurement method: arm_1 method
- Submission: NICCS page
2. Assessment environment
| item | value |
|---|---|
| processor | Qualcomm Oryon (CPU 2, one core) |
| machine | ASUS Vivobook S 15 |
| clock | fixed 2.71 GHz (governor performance, minimum = maximum), boost off, SMT none |
| memory | 30562 MiB |
| OS / kernel | Ubuntu 26.04.1 LTS / 7.0.0-34-generic |
| compiler / build tool | gcc (Ubuntu 15.2.0-16ubuntu1) 15.2.0 / cmake version 4.2.3 |
| campaign start / end (UTC) | 2026-09-28T15:05:46 / 2026-09-29T08:43:52 |
3. Functional testing (KAT)
Each library was checked against the submitted KAT vectors (SHA-256 manifest kem-07/kat.sha256 in the harness) before timing.
| instance | build flags | KAT |
|---|---|---|
BRQC-128 |
harness-default | BUILDFAIL |
BRQC-256 |
harness-default | BUILDFAIL |
BRQC-512 |
harness-default | BUILDFAIL |
4. Performance
| instance | operation | mean cycles | mean time | ops/s | median trial | n (trials × iters) |
|---|---|---|---|---|---|---|
5. Resource consumption
Static memory is approximated by the library's loadable ELF segments; peak memory is the process high-water mark (VmHWM) including the benchmark driver and libc, so both are upper-bound proxies rather than isolated algorithm memory.
| instance | operation | static: ELF image (bytes) | baseline RSS | peak RSS |
|---|---|---|---|---|
6. Transmission and storage overhead
External public-key, ciphertext and signature sizes follow the curated performance/external_sizes.csv catalog; secret-key and shared-secret lengths remain API figures. See the size audit for disagreements.
| instance | public key | secret key | ciphertext | shared secret |
|---|---|---|---|---|
Symmetric primitives
Survey verdict: ICCS-only — pseudohash for G/H; seed expansion via per-seed ICCS DRNG instances; XKCP Keccak dead
Share of each operation spent in the ICCS placeholder hash functions and in the ICCS DRNG (reference build, measured in the same run with link-time wrappers):
| instance | operation | pseudohash/XOF/sm3 | DRNG | calls per operation |
|---|---|---|---|---|
7. Raw evidence index
Paths are relative to performance/data/arm_1/ in the harness; each JSON file records its commands, environment and trials.
| instance | item | file |
|---|---|---|
Scripts: performance/campaign.py, performance/ngcc_perf.c, performance/hashprof/ in the harness.
