Claim:
1. A computer-implemented method for enabling secure execution of provisioning images within semiconductor chips, the method comprising: generating a first semiconductor chip that includes a key provision key (KPK) set, wherein the KPK set includes a first KPK located at a first KPK index and a second KPK located at a second KPK index; configuring the semiconductor chip with instructions that, upon execution in conjunction with the first KPK index in a secure provisioning mode at a second entity, cause a first encrypted provisioning image that reflects a first entity-specific functionality to be securely decrypted and executed based on the first KPK without disclosing outside of the semiconductor chip the first KPK or the second KPK; and sending the first semiconductor chip, the first KPK, and the first KPK index to the first entity, but keeping the second KPK secret from the first entity.
