“What ?”

“TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device).”

SLIDE 4

“Truecrypt.”

  • Creates a virtual encrypted disk within a file and mounts it as a real

disk.

  • Encrypts an entire partition or storage device such as USB flash drive
  • r hard drive.
  • Encrypts a partition or drive where Windows is installed (pre-boot

authentication).

Why ?

  • Protection of IP
  • Paranoia (USA Act)‏
  • Protection of personal information

“The final straw.”

  • Plausible Deniability

1) Hidden volume (steganography) and hidden operating system. 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data).

How ?

* Encryption is automatic, real-time (on-the-fly) and transparent. * Encryption algorithms: AES-256, Serpent, and Twofish. Mode of

  • peration: XTS

* No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys.

Encryption Algorithms

  • AES-256
  • Serpent
  • Twofish

Hashing Algorithms

  • Ripemd-160
  • sha-512
  • whirlpool

Shortfalls.

Doesn't support multi-boot configurations where a bootloader is installed in the MBR (grub / lilo)‏ When encrypting an entire drive you can't create any logical partitions

Real World Application.

  • Full disc encryption for mobile users (laptop / r-drive)‏
  • Full disc encryption for remote servers in hostile environments
  • Safe storage of data off site (backups / configuration files)‏
