VEST Corporation - Cloning Prevention

Cloning Prevention

antenna-on-chip Our contactless XS microchips implement our small keyed hash function XS that doubles as a stream cipher and as a physically unclonable function to deliver the world’s first Cryptographically Secure Physically Unclonable Microchips.

ASIC prototype hardware requirements:

Silicon technology: 130nm
Size including antenna: 1×1mm, can be embedded in paper
Operational frequency: 13.56 MHz
Reading distance: <3mm inside a shielded reader without interference
Communication protocol: 14443 standard
Only standard components
Input: 80 to 256 bits of data (challenge), depending on the available area
Output: continuously produced XS keystream (authenticated response)
Security: 80 to 256 bits, depending on the available area
Is not reprogrammable, only personalised once at the factory
Only a minimal amount of OTP memory to store the secret key

Microchips implementing our cloning prevention technology can also be easily paired without a connection with other existing microchips. Unclonability of the small XS chip can vouch for the other components to be legitimate. Thus other chips do not need to implement any of the expensive but futile side-channel attack prevention techniques or any other equally futile software-based “anti-cloning” tricks.

VEST Corporation cloning prevention technology is also The DRM [Digital Rights Management] solution that succeeds to deliver what all the software attempts at DRM have failed to deliver for many years.
