[ISN] Da Vinci Code inspires secure USB drive

Taking inspiration from Dan Brownâs The Da Vinci Code, a US startup has fused a USB flash drive with a âCryptexâ device, a metal cylinder that can only be opened by setting the correct combination on a rotating barrel.

The latest Crypteks (notice the different spelling) is not the first device of its kind â designs have been circulating on the Internet since the Da Vinci code resurrected what is probably an older idea â but it does look like the most interesting to date.

The external 8cm barrel comprises five aluminium alloy rotating rings on which each has printed the 26 letters of the English alphabet. Removing the USB flash drive from within the cylinder involves entering the correct combination of which there are 14,348,907 possible combinations thanks to the decision to adopt letters on each ring rather than numbers.

The USB drive contained within the barrel uses 256-bit AES encryption, adding another layer of security to the physical design, with a customisable auto-format option for incorrectly-entered passwords.
