How do I use from security token for FIDO?

I have a USB security token, that is used for generate key-pair and save secure data in it's memory.

Communication with this token is by c++ library. Like readMemory() and writeMemory() also genKeyPair().

I want to use this token in FIDO solution. What is way to connect the token and communicate with it?

I visit fidoalliance.org web site.

If your token is not "open" (i.e. you cannot update its firmware) and if it is not a FIDO device (Yubikey, Feitian, ...), I'm afraid you can't.

If you can put some code in it, you will have to (at least):

• Implement U2F HID protocol so that your token enumerates as a FIDO-HID device and communicates as such
• Implement U2F messages to answer U2F requests. The process of these messages may use your token API.
• Test it
