BQ28Z610: Authentication Guidance

Part Number: BQ28Z610
Other Parts Discussed in Thread: BQSTUDIO, BQ78350,

Hi,

Thanks for your sharing.

I have a question, why don't you use the same thing as defined in the datasheet?

Generate SHA-1 input block B1 of 512 bytes (total input = 128-bit authentication key KD + 160-bit message M + 1 + 159 0s + 100100000).

I can't figure out how to go from

I use : https://www.liavaag.org/English/SHA-Generator/HMAC/

Have a nice day.

Hi,

With the BQ78350 I can't see the Authentication tab, with others BQ I have the Authentication tab.

Can you help me to display the Authentication tab with the BQ78350 ?

Have a nice day.

Hello,

Are you using the BQ78350 and not the BQ28Z610? BqStudio does not support the Authentication tab for the BQ78350.

Jonny.

I think the datasheet of the BQ78350 as an error :

I solved my problem using only :

total input = 128-bit authentication key KD + 160-bit message

Not :

total input = 128-bit authentication key KD + 160-bit message M + 1 + 159 0s + 100100000

I have lost two days because of this error in the datasheet !
