Cryptographic Integrity Hashing
Per-File SHA-3 / BLAKE3 Hash Verification
Cryptographic integrity hashing (SHA-3, BLAKE3) verifying every file matches its recorded hash — detecting silent data corruption.
Purpose
Cryptographic integrity hashing (SHA-3, BLAKE3) verifying every file matches its recorded hash — detecting silent data corruption.
Context
Child of L2-DVT-INTEG within the Lunar Ark system
Principles
- ▸SHA-3 (FIPS 202) cryptographic hash
- ▸BLAKE3 high-speed alternative
- ▸Per-file hash recorded in immutable log
- ▸Periodic re-verification
- ▸Hash log in MRAM for tamper resistance
Typical implementations
- ▸Cryptographic hash standards (FIPS 202)
- ▸Industrial data integrity systems
- ▸Blockchain hash chains
Lunar considerations
- ▸Detects bit errors beyond ECC's correction range
- ▸Long-mission cryptographic standards may evolve — algorithm agility
- ▸Coordinated with L3-COM-CRYPT-AUTH
