6.4 Stealth mode
R&S Trusted Disk's stealth mode hides the existence of an R&S Trusted Disk encryp-
ted system. For this, two Windows installations exist on one workstation ‒ an encryp-
ted Windows installation and an unencrypted Windows installation.
Boot scenarios in stealth mode:
●
If a smart card is connected, the encrypted system starts (after a successful pre-
boot authentication).
●
If no smart card is connected, the non-encrypted system starts. In this scenario, the
pre-boot authentication is not displayed, i.e. the existence of an encrypted system
is not disclosed.
Stealth mode is supported on the following systems:
● UEFI/GPT................................................................................................................33
● Legacy BIOS/MBR..................................................................................................36
6.4.1 UEFI/GPT
