  • Hardware Security Module that Enforces Signature Requirements
    Publication number: 20210344508
    Abstract: In an embodiment, an HSM may provide a cryptographic signature service. The HSM may maintain key/token pairs for various users/entities and for a first entity for which signature may be desired. The HSM may ensure that the requirements for the entity's signature are met, and then may apply the entity's signature. In an embodiment, the HSM may augment the private token for the first entity with the public keys of users/entities which are to approve the entity's signature. As the approvals are received, the HSM may record the approvals and may apply the signature once the approvals are received.
