2 About R&S Trusted Disk
R&S Trusted Disk is a full-disk encryption solution that encrypts user data, the operat-
ing system and any temporary data. It uses a transparent real-time encryption method
that ensures a smoothly running workstation. Pre-boot authentication secures the
workstation from unauthorized access. To boot up a workstation, users have to identify
themselves by connecting a smart card and entering a PIN.
R&S Trusted Disk was developed based on BSI standards, including up-to-date ran-
dom number generation and flexible rekeying to ensure high-level security.
