Cryptographic Execution Gating
Definition
A security pattern where every approved agent action receives a cryptographic proof of admissibility — a signed execution token that contains the state hash, approved payload, and expiry time. The target system (database, API) can then verify that the action was explicitly approved by the governance layer before executing it. Without a valid token, execution is rejected.
Why It Matters
Standard permit/deny decisions don't prevent replay attacks, token forgery, or TOCTOU exploits. Cryptographic execution gating provides non-repudiation — mathematical proof that an action was evaluated, approved, and committed against a specific system state. This is the difference between access control and cryptographic governance.
How Exogram Addresses This
Exogram generates signed execution tokens (JWTs) containing SHA-256 state hashes, approved payloads, and TTL expiry. The commit endpoint re-verifies the state hash — if state has drifted, the commit is rejected. This is cryptographic proof-of-admissibility, not just a boolean allow/deny decision.
