Optima x561 Reference Guide

System integrators, owners, and end users must take precautions to mitigate the 
chance of data loss.  Data encrypted by any program utilizing the Trusted 
Platform Module (TPM) may become inaccessible or unrecoverable if any of 
the following occurs:   

• 

Lost Password: 

 Loss of any of the passwords associated with the TPM 

will render encrypted data inaccessible.  No password recovery is 
available.  Read the Security Precautions for Password Procedures. 

• 

Hard Drive Failure: 

 In the event of a hard disk (or other storage media) 

failure that contains encrypted data, an image of the hard disk (or other 
storage media) must be restored from backup before access to encrypted 
data may become available.  The owner/user should backup the system 
hard disk on a regular basis.  Read the Security Precautions below for 
Hard Drive Backup Procedures

. 

• 

Platform Failure:

  In the event of a platform failure and/or replacement of 

the desktop board, recovery procedures may allow migratable keys to be 
recovered and may restore access to encrypted data.  All non-migratable 
keys and their associated data will be lost.  Both the Wave Systems* 
EMBASSY* Security Center and Wave Systems EMBASSY Trust Suite 
utilize migratable keys.  Please check any other software that accesses the 
TPM for migratability.  Read the Security Precautions for Emergency 
Recovery File Back Up Procedures. 

• 

Loss of Trusted Platform Module Ownership:

  Trusted Platform 

Module Ownership/contents may be cleared (via a BIOS switch) to allow 
for the transfer of a system to a new owner.  If TPM ownership is cleared, 
either intentionally or in error, recovery procedures may allow the 
migratable keys to be recovered and may restore access to encrypted data.
