The CmStick is the heart of the CodeMeter Digital
Rights Management system as USB device in a very
small and noble case. It contains a Smart Card chip
including a secure memory of about 328 kByte
available for storing thousands of licenses. The basic
idea of the revolutionary CodeMeter concept is that
licenses can be stored for many products even from
many different vendors at the same time.
License Options are at least: Text (description of an
entry), Unit Counter (number of runs or actually run
time of a license), Activation Time (the license is valid
from), Expiration Time (the license is valid until),
Usage Period (starts at first time), Maintenance Period
(according to release date), Feature Map (up to 32
modules or versions), License Quantity (concurrent
use / floating network licenses), Protected Data /
Extended Protected Data (128×256 bytes read-only
data), Hidden Data (128×256 bytes only readable
with password; usable as secret/private key), Secret
Data (128×256 bytes non-readable, only usable as
secret/private key), User Data (unsecured 256 bytes),
Customer Owned License Information (256 bytes).
Used algorithms: 128 bit AES, SHA-256, 2048 bit RSA,
224 bit ECC.
The used SmartCard chip contains a random number
generator and fulfills EAL 5+ (Common Criteria
certified). The CmStick has a green and a red LED.
