License cryptogram

Address : 020A (bank 2, register 0A)

Size : 32 bytes

Type : array (variable length)

Default : empty

Description

This register is available to store a proof that the Application name and License key are genuine.

Remark

Integrators and solution providers are welcomed to create a bundle tying the device to an accompanying software. This register may store a proof that the device has been personalized by the provider of the software. An easy way to do so is to compute an HMAC over the device's serial number, the Application Name and the Application License. The application may verify the HMAC (provided that it knows the secret key used to compute it). This register has a size of 32 bytes, which allows to use HMAC-SHA256.
