Abstract
According to embodiments of the present disclosure, a dynamic key distribution system is provided. The dynamic key distribution includes computer-executable instructions to encrypt, using a first Security Protocol and Data Model (SPDM)-enabled device conforming to a SPDM specification, an original Pre-Shared Key (PSK) with a SPDM identity certificate of the first SPDM-enabled device, wherein the original PSK is associated with a second SPDM-enabled device. The instructions are also configured to provision the encrypted PSK in the second SPDM-enabled device, and authenticate the second SPDM-enabled device by decrypting the encrypted PSK to obtain the original PSK using an SPDM protocol.
