https://devzone.nordicsemi.com/f/nordic-q-a/115129/support-for-ed25519-in-nordic-secure-immutable-bootloader-nsibAre there any current or future plans to implement Curve25519 (also known as Ed25519) for the NSIB? It appears that the CryptoCell 310 supports it, and it is recommended by NIST in FIPS 186-5 (though secp256r1 is also suitable).en-USTelligent Community 13Thu, 03 Oct 2024 07:47:03 GMThttps://devzone.nordicsemi.com/thread/504786?ContentTypeID=1Thu, 03 Oct 2024 07:47:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:71bd2d8b-3eb1-4486-8b3b-9038c2ff611fMenon<p><strong>Hello,</strong></p> <p>Sorry for the delay in getting back to you. I’ve been checking internally to see if there is current support for Curve25519 for the NSIB, but I haven&#39;t heard back from the team yet. It might take a bit more time.</p> <p>I am not able to answer questions about our timeline, as we don’t share roadmaps or timeframes here in DevZone.
