DigiSAFE DiskCrypt Mobile – Simply Secure! Your data on the go

DigiSAFE DiskCrypt Mobile (DCM300) is the world’s first encrypting 2.5” USB 2.0 hard drive enclosure with smartcard protection. It employs real-time hardware encryption for protecting the data on the hard drive and smartcard technology for authentication. Designed to encrypt all data on-the-fly, DCM300 requires no software installation and operates independently of the operating system. A unique feature of DCM300 is that it carries a keypad allowing you to key in your PIN directly on to the unit. This ensures protection from key-loggers that may be recording your keystrokes. Together with full disk encryption and smartcard based authentication, this feature gives you the ultimate level of protection with an unrivalled ease of use.

Use Case

Built-in Key Management Functions

Through administrative functions, DCM Onyx allows you to create and manage your own encryption keys on the smart card.

Use Cases:

1. Secure portable storage/back-up

DCM300 ensures that all the data stored (or backed up) on the hard disk is fully encrypted and safe from the prying eyes. What’s more, the smartcard (containing the encryption key) as well as the correct PIN are both required to unlock the data, giving you the ultimate level of protection, yet ease of use.

2. Booting an operating system from DCM300

An operating system such as Linux can be installed on DCM300 to allow the user to carry a “portable OS”. This also means your operating system is fully encrypted on DCM300. Of course, both the host machine and the operating system must support booting from a USB device in the first place. Approach your OS vendor to advise.
