Patent attributes
A virtual hardware security module (“HSM”) is used to perform cryptographic operations. The virtual HSM may provision and coordinate requests between one or more HSMs within a fleet of HSMs. A set of cryptographic keys and/or digital certificates may be exchanged between a client and the virtual HSM such that the client and the virtual HSM may communicate with each other via a cryptographically protected communication session. The fleet of HSMs of a virtual HSM may be scaled up or scaled down according to various criteria. Cryptographic key material may be propagated between HSMs of the fleet using a fleet transfer key. Digital certificates may be used to demonstrate that one or more cryptographic keys were generated by a service provider and/or manufacturer.
