Abstract
An apparatus for cloud key management may include a networking interface, a memory, and a processor, coupled to the memory and the networking interface, the networking interface to couple the apparatus to one or more endpoint servers (EPSs) of a cloud service provider (CSP), each EPS including a hardware accelerator, and a management node (MN) of the CSP. The apparatus may further include an accelerator functional unit (AFU) developer interface module operated by the processor to receive cryptographic material (CM) for each of one or more AFU developers (AFUDs) and store it into the memory, the CM includes a public key hash (PKH), and an encryption key (EK) to decrypt an AFU of the AFUD. The apparatus may also include an EK communication module operated by the processor to: receive, from the MN, a request to send to a targeted EPS an encrypted lookup table (LUT), the LUT including PKHs and associated EKs for a set of the one or more AFUDs from which the targeted EPS is authorized to receive AFUs, and in response to the request, send, to the targeted EPS, the LUT.
