keys created by the TPM encapsulate system application encryption keys to provide an additional
layer of security for sensitive system data.
The fundamental capabilities of the TPM include:
• Platform authentication
• Sensitive information protection
• Data integrity
• System privacy
IMPORTANT: You must run the supported version of the HP-UX operating system to utilize
the TPM security component.
