Abstract: A device, comprising: an input; and a plurality of processing modules, the plurality of processing modules comprising a first processing module and a second processing module, the device being configured to: responsive to a first command received through the input, execute, on the first processing module, a cryptographic operation corresponding to the first command; responsive to a second command received through the input, execute, on the second processing module, a cryptographic operation corresponding to the second command.

Abstract: A hardware security module (HSM) appliance that include one or more HSM(s) is described. The HSM appliance provides improved cooling of HSM appliance components including the HSM(s), improved maintenance, and improved security. In an embodiment, the HSM(s) and a processor module that controls operation of the HSM(s) are positioned relative to one another whereby the HSM(s) and the processor module overlap one another. In another embodiment, cooling air ducting may cover the HSM(s) and the processor module, with the cooling air ducting directing cooling air over the HSM(s) and the processor module.
