More Information
Summary:A security processing unit is configured to manage cryptographic keys. In some instances, the security processing unit may comprise a co-processing unit that includes memory, one or more processors, and other components to perform operations in a secure environment. A component that is external to the security processing unit may communicate with the security processing unit to generate a cryptographic key, manage access to a cryptographic key, encrypt/decrypt data with a cryptographic key, or otherwise utilize a cryptographic key. The external component may comprise a central processing unit, an application, and/or any other hardware or software component that is located outside the security processing unit.
