Core engineering and protocols for Quantum-Resilient API Token Exchange.
OAuth 2.0 access tokens and JSON Web Tokens often travel across multiple intermediate API gateways, CDNs, and microservices. If intercepted and archived, quantum adversaries will eventually decrypt tokens containing sensitive identity claims and authorization scopes. MLKEMSecurity seals tokens using JSON Web Encryption backed by ML-KEM-768.
By encapsulating tokens specifically to the target microservice's public key, intermediate gateways can route requests without decrypting the payload. Only the designated destination pod possess the ML-KEM private key necessary to decapsulate the symmetric session key and inspect the authorization claims.
