Nitrokey HSM2 N-of-M authentication --register-public-key Incorrect parameters in APDU error

Hi I’m trying to use N-of-M authentication (not DKEK shares) based on the following:


I built opensc with the PR but it fails to when trying to --register-public-key.
I have two Nitrokey HSM2s, HSM A and HSM B. They are both on firmware 3.4

  1. Plug HSM A in
  2. Initialize for public key auth
./bin/sc-hsm-tool --initialize --required-pub-keys 1 --public-key-auth 1

# check to make sure it took effect
./bin/sc-hsm-tool --public-key-auth-status
  1. Unplug HSM A, plug HSM B in

  2. initialize HSM B, generate an RSA key, export it

./bin/sc-hsm-tool  --initialize
./bin/pkcs11-tool --module ./lib/opensc-pkcs11.so --login --pin <pin> --keypairgen --key-type rsa:2048 --id 17 --label "RSA for m-of-n"
./bin/sc-hsm-tool --export-for-pub-key-auth key0.pub -i 1
  1. unplug HSM B, plug HSM A in

  2. attempting to register the public key fails

$ ./bin/sc-hsm-tool  --register-public-key ./key0.pub
Using reader with a card: Nitrokey Nitrokey HSM (DENK01054880000         ) 00 00
Adding the key issued to 'DENK010493800001' on device 'DENK010493800000'.
sc_card_ctl(*, SC_CARDCTL_SC_HSM_REGISTER_PUBLIC_KEY, *) failed with Incorrect parameters in APDU

I would appreciate any help getting this to work, thanks!

The key used for authentication must be an ECDSA key with brainpoolP256r1 curve. A RSA key can not be registered for public key authentication.

I don’t know the code from the pull-request, so I’d suggest to try this in the Smart Card Shell as described in the document.

Thanks, that helps! I’ll try exporting an ECDSA key with brainpoolP256r1 and see if that works.

Yes, but unfortunately it doesn’t build without extra effort on ubuntu 18.04 (this might be user error, I’m not familiar with the java ecosystem) and it would be preferable to use publicly available code. Anyways that was my backup plan, so I’ll go forward with that if exporting the ECDSA key doesn’t work.

Appreciate the help!
