Cloud HSM

Definitions

1. A cloud-hosted hardware security module service that stores and uses cryptographic keys inside dedicated tamper-resistant hardware under provider-managed infrastructure. It is used when strong key protection is needed without running on-prem HSMs.

   In plain English: A cloud service providing hardware-protected key management.

   Example: "The signing service moved to a cloud HSM so private keys would never leave certified hardware."
