Designing physical and electrical isolation barriers separating unclassified black network components from secret red data.
In defense communications, unencrypted data (Red) must never share power planes, ground lines, or memory buses with external RF transceiver circuits (Black). RadioHSM enforces this separation through physically isolated silicon dies mounted within a single hermetic package, connected only by an internal optical data diode.
RadioHSM supports modern cryptographic suites (NSA Suite A and Commercial National Security Algorithm Suite - CNSA), executing AES-256-GCM and elliptic curve Diffie-Hellman handshakes entirely within the Red secure enclave before releasing ciphertext to the Black RF stage.
