Abstract
Fault-tolerant storage of cryptographic information maintained on a fleet of HSMs may be provided by dividing the cryptographic information into a number of stripes which are distributed and stored on individual HSMs in the HSM fleet. Parity information is generated which allows one or more stripes to be regenerated if one or more stripes becomes corrupt or is lost. The parity information may be stored on an HSM in the HSM fleet, or outside the fleet on a storage service, HSM management hub, tangible computer-readable media, or other device. If an HSM in the HSM fleet fails, resulting in the loss of a stripe, an HSM in the fleet can recover the missing stripe by re-creating the missing stripe from the remaining stripes combined with the parity information. In some examples, stripes are mirrored within the fleet of HSMs.
