Abstract: ABSTRACT METHOD AND SYSTEM FOR HARDWARE-ATTESTED DUAL-CREDENTIAL AUTHENTICATION OF ELECTRONIC PAYMENT INSTRUCTIONS A system and method for hardware-attested dual-credential authentication of electronic payment instructions are described. In one example, a mobile device generates two credentials within a single payment instruction: a first credential proving possession of a credential-generation key confined to device secure hardware, validated by a central routing authority; and a second credential computed under a transaction key derived by key agreement between the mobile device and an account-holding institution, where the central routing authority routes only public keys and is structurally incapable of deriving the shared secret or forging the second credential, enabling independent issuer verification. A per-transaction ephemeral key is generated in software and authenticated by a hardware-resident, once- attested long-term device key. The central routing authority additionally validates a platform attestation chain once and issues a domestically rooted device certificate accepted in place of re-validating the platform chain across multiple institutional relationships.
