Abstract
A system for generation, storage, administration and use of one or more digital secrets in association with a portable electronic device. The system comprises a highly secured memory that stores only one or more master keys; a keystore implemented in the portable electronic device outside of the highly secured memory; one or more cryptography applets implemented in the portable electronic device outside of the highly secured memory; and a highly trusted intermediary module (ThIM) implemented outside of the highly secured memory, the ThIM establishes and manages a highly trusted communication conduit between the highly secured memory, the keystore, the one or more cryptography applets, and at least one third party application, wherein the ThIM polls the portable electronic device, the highly secured memory, the keystore, the one or more cryptography applets to determine a trust score, initialization cost, and transaction cost for each component in the portable electronic device, the ThIM providing a trusted third party application acceptable interaction parameters based on the trust score, the initialization cost, and the transaction cost, the ThIM managing highly trusted communicat…
