sign-07 CS — performance on x86-64 (system x86_1)

Independent measurement following the structure of the NICCS x86 self-assessment guide, §3.5 (1)–(7). Not a submitter self-assessment.

3. Functional testing (KAT)

Each library was checked against the submitted KAT vectors (SHA-256 manifest sign-07/kat.sha256 in the harness) before timing.

instance build flags KAT
CS-128 guide PASS
CS-256 guide PASS
CS-512 guide PASS

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.

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.

CS-128 976 1888 1548
CS-256 1760 3968 3164
CS-512 4288 7808 5975

Symmetric primitives

Survey verdict: ICCS-only

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
CS-128 keygen 4.7% 58% drng 16, pseudoXOF 2
CS-128 sign 56% 12% drng 75.3, pseudoXOF 16.4
CS-128 verify 6.3% 58% drng 33, pseudoXOF 3
CS-256 keygen 10% 60% drng 16, pseudoXOF 2
CS-256 sign 49% 8.4% drng 154, pseudoXOF 17.7
CS-256 verify 11% 59% drng 54, pseudoXOF 3
CS-512 keygen 14% 58% drng 42.1, pseudoXOF 2
CS-512 sign 62% 6.3% drng 430, pseudoXOF 32.7

7. Raw evidence index

Paths are relative to performance/data/x86_1/ in the harness; each JSON file records its commands, environment and trials.
