SE05 and ICODE DNA verify original signature

[Liad]

Hi community,

I develop a medical device that reads RFID tags that use ICODE DNA technology.

As part of accessing the tag, there must be a process of tag signature verification (AN11600).

Also, I use for my crypto operations the NXP EdgeLcok SE05 device.

The problem is the tag signature verification example that mentioned in AN11600 heavily uses the OpenSSL lib which I can't use in my limited MCU.

My question is, can I perform the same Signature Verification that mentions in AN11600 or similar via the EdgeLock?

Hi @Liad ,

Actually the ECC curve used for ICODE DNA original signature is not supported by SE05x, so I am afraid you can not use SE05x for that purpose.

Please kindly refer to "Table 1. Supported EC curves" on page 7 of https://www.nxp.com/docs/en/application-note/AN12413.pdf for more details.

Hope that makes sense,

Have a great day,
Kan
