Its 2023 and the irDA technology is already ancient and obsolete, but still used in many applications and fields including Medical , Military, Diving Oceanography and more.
The problem is that because the technology is old and obsolete, there is not much support from the Operating Systems for the most of the old devices still available (Old Stock). In addition to that the companies that were producing these irDA devices are no longer interested to continue manufacturing and maintaining product stocks, due to the small market.
The USB irDA transceiver fills that gap, providing irDA connectivity for modern operating systems. It is supported in Linux , MAC OS X and Windows 10 and 11.
Irdroid authKi is a Open Source crypto Authentication USB Dongle, with built-in hardware support for Asymmetric Sign, Verify, Key Agreement for ECDSA – Elliptic curve digital signature algorithm, ECDH – Elliptic Curve Diffie-Hellman and NIST Standard P256 Elliptic Curve Support, thanks to the built-in Cryptographic Co-Processor with Secure Hardware-Based Key Storage – ATECC608B by Microchip.
While experimenting with hardware Crypto elements for a Company/Project that I am working, I needed a way to easily access the crypto element via USB, so I designed and built the authKi, and I think that it will be useful for others working in the field There is no open source software and hardware solution that provides the ability to experiment with hardware based secure elements / crypto accelerators. Consequently I found it useful and easy to use for SSH ECDSA public/private keypair authentication and authentication with Git / Github
The irDA protocol though ancient is still used for some applications such as Medical, in the Energy Sector – for power meter communications and also military applications.
The challenge is not that there are not USB irDA adapters available. It is rather the lack of software support for newer modern operating systems.
This gap is filled by a company called Hardware Group Ltd, which offers a inexpensive USB irDA adapter module, compatible and usable on modern operating systems . It is currently compatible with Linux, Mac OS X and Windows 7, Windows 8 and Windows 10.
The unit is a possible replacement for the following USB irDA adapters that are used for Medical Applications:
