Except for the backup requirements, the Gemalto IDPrime MD seems to fit your requirements. Some caveats:
It tops at 2048 bits for RSA; for ECC, it supports only three standard NIST curves (P-256, P-384 and P-521), not custom curves.
From experience, at the APDU level, the signature operation is really a command to do a modular exponentiation with the ...
I think the most useful way to answer this question is to start with the hardest part of the answer and work my way down
should have as much open-source firmware or security certifications as possible.
As such my starting point would be the coreboot page, since that lists systems which support opensource firmware
I'm picking thinkpads here. I'm ...
One important question you need to ask yourself is if you need industrial build quality and long term hardware support, or a research/prototype platform.
If you need an industrial PC, I don't have any <100 dollar options for you, but you might spend 100-200 dollars on a Compulab product. I have pretty good experiences with them, the hardware design seems ...
The Sesame smart lock from Candyhouse allows for bluetooth operation, as many of these products provide, but also allows one to open the deadbolt manually. When the lock is operated manually, from within or outside, logging and notification is available.
This may not meet your requirements, as one cannot determine if the action is performed with a key or by ...
I think what you're looking for is:
The Feitian ePass2003
(or some other token from their ePass line)
It costs less than a YubiHSM - Feitian sells them at 70USD for five pieces + customs, taxes and shipping
It supports RSA, AES and 3DES with card-stored keys
It supports the Windows CSP and has a PKCS#11 library
It claims support for Linux, Windows and OS X
You didn't specify operating system, but the LG Extravert 2 meets all requirements. Just take the SIM card out. Has camera. Has SD Card for exporting data. Has Qwerty keyboard. Is small. Is less than $100. Is not no name Chinese. Has an app for notes. Is PIN protected. Not sure about encryption, but there's probably an Android app for that.
OK, to give you a solid understanding of which Yubikey you need you first need to understand what each single one can offer you.
In principle, there are three "levels" of functionality regarding the Yubikeys.
Level 1: U2F
All Yubikeys offer support for the U2F authentication protocol which was originally designed as a secure, anonymous second ...
