Isolated machine interface
IN OPERATION
The institutional API is a separate machine protocol. Machine access is never treated as an administrator session. Refused requests are logged, repeated failures per sender are throttled.
Bounded requests
IN OPERATION
Every request has a fixed size limit, institutional requests at most 16 KB. Transfers that are too slow are aborted. This protects against overload by oversized or deliberately delayed requests.
Outbound connections only on an allowlist
IN OPERATION
The System connects only to destinations listed in the sealed code or the configuration. Internal and private networks are blocked, every redirect is checked on its own, every block is logged. This prevents attacks that try to use the System as a stepping stone (SSRF).
Code integrity seal
IN OPERATION
At start-up the System checks every program file against a sealed manifest. In enforcement mode it refuses to start on any deviation instead of running with altered code.
Access rules that lock when in doubt
IN OPERATION
Where no rule exists, only an administrator has access. The rule registers themselves are locked against direct changes, even for administrators. Changes only go through three approvals by different people.
Login protection
IN OPERATION
Failed login attempts are counted and limited. Sessions expire after a fixed time.
Gap-free log
IN OPERATION
Security-relevant events go into an audit log that can only be appended to and is linked as a hash chain. Any later change is detected.
Post-quantum receipts
IN OPERATION
Every check ends in a receipt with Ed25519 and ML-DSA-87, chained with SHA-384. The daily root additionally carries SLH-DSA-SHA2-256s. A receipt is valid only if both signatures verify.
Compromised-scheme issuance block
IN OPERATION
If a scheme is marked as compromised, the System immediately stops issuing with it. Instead there is a technical abort with a failure record and an alarm.
Hybrid key exchange
IN OPERATION
Keys are exchanged with X25519 and ML-KEM-1024 (FIPS 203), against today’s and future attacks.
Daily chain check
IN OPERATION
Every night the System checks its evidence chains. If a chain breaks, a critical alarm is raised for each affected record before retention deadlines apply.
Keys stay on the server
IN OPERATION
Signing keys are generated locally, never displayed and never transmitted. Without them the System issues no receipt.
IN OPERATION: runs in the current System state. BUILT IN · ACTIVE AFTER SETUP: present and tested, becomes active with your configuration.
