USB stick encryption

What do we want?

• Our files to be (relatively) safe
• To be able to use them on every pc

"It's dangerous to put it in without protection"

The big issue

• In order to decipher your files you must have a program that has the corresponding deciphering algorithm
• Which may be an issue since usb sticks tend to be put into foreign hardware, eg university/library/your friend's computers

The big issue

Portability is key.

Solutions we will look at today:

• Linux and Windows support
• Linux exclusive
• Proprietary

Due to the nature of usb sticks I've limited my research to the "Batteries included" software!!!

Windows & Linux

• PKZIP stream cipher for support from XP onwards
• PKZIP stream cipher is insecure (http://math.ucr.edu/~mike/zipattacks.pdf )
• Password is shown in plain text
• demo

Linux only

• Bullet One
• Bullet Two
• Bullet Three

Proprietary solutions

• Platform independent
• "government grade security"
• Expensive as f*ck (140$ for 8gb)
