PN7642 Secure key store

artem_pn — Wed, 03 Jul 2024 15:10:00 GMT

Hello!

I`m using PN7642. There are a lot of different key types that is possible to store and which are already stored in secure key store. Is there any document that describes in more details these keys purposes and use cases? Are they used for PICC authentication and data encryption during communication or they are used for other purposes?

Thanks in advance!

Artem

Hello @artem_pn,

Hope you are doing well.

A description of these keys can be found in PN7642 Data Sheet, Section 9.12.3 Secure Key Store. Also, I could recommend you consulting PN76 family instruction manual, Section 4.2 Secured Key Mode; and perhaps PN7642 Secure Key Mode demo application.

Regards,
Eduardo.
