3. What is the advantage of using Rocsafe over
encryption software to protect data?
• Unlike existing software solutions, Rocsafe encrypts
very single sector of the hard disk. This means all
temporary files, all partitions and even the boot sector is
encrypted.
• One major disadvantage of existing software disk
encryption products is that they are Operating System
(mostly Windows) dependent. Rocsafe is independent of
the OS or the host system BIOS and thus support any
OS.
• Rocsafe does not involve any tedious and error-prone
software installation and configuration. Just plug Rocsafe
in the notebook, authenticate yourself and you are ready
to go.
• Once installed, Rocsafe does not require any
maintenance or patches thus reducing the total cost of
ownership of the product.
• There are also no performance overheads due to
encryption/decryption of data, unlike software-based
solutions.
4 . Does Rocsafe support two-factor authentication?
Yes. If you purchase the optional Rocsecure, Rocsafe's
Token mode can enabled to support two-factor
authentication.

5. What happens when the user forgets the password or
loses the USB token?
In such a case, the administrator's password can be used
to reset the user password. Thus, the user will able to
resume his/her work even after forgetting the password or
losing the token.
6. Is the boot sector of Rocsafe also encrypted?
Yes, Rocsafe encrypts every sector of the hard disk drive.
This means every single byte of information being stored
on the hard disk is encrypted.
7. Does encryption slow down the performance of
Rocsafe in comparison with normal, unencrypted hard
disks?
No. The on-the-fly encryption and decryption engine in
Rocsafe is faster than the data transfer speed of the IDE
interface and thus does not incur any performance
overheads.
8. How strong is the encryption of Rocsafe?
Rocsafe uses the NIST certified DES and Triple-DES
encryption schemes. The key-strength offered by Rocsafe
currently is 64, 128 and 192 bits. Key strength of 64
bits provides sufficient security for most notebook users.
If the data is highly confidential, key strengths of 128
and 192 bits are recommended.
