DiceKeysis a physical mechanism for creating and storing a 192-bit key. The idea is that you roll a special set of twenty-five dice, put them into a plastic jig, and then use an app to convert those dice into a key. You can then use that key for a variety of purposes, and regen...
In DICE terminology, the key for Layer 0 generated by DICE Core is called the Compound Device Identifier (CDI). The key derivation process can be stacked infinitely, although a typical application might use three levels: DICE Core, a bootloader, and the application code itself. DICE follows a...
This is why the manufacturer provides instructions on how to verify dice seed derivation with a Python script. This application does the same but goes one step further: It also allows you to verify the receive addresses derived from the seed. This covers the scenario where a malicious COLDCARD...
HMAC-based key derivation function (HKDF)described inRFC5869is used to expand the external seed to the desired length. Random.org Random.orgis a website that produces "true random numbers" based on atmospheric noise captured by several radios tuned between stations. The service has existed since...
Hi, I've been following the derivation of wolfram mathworld for this problem and I'm running into some trouble regarding the summation indices. Currently I am at the step where we have found that (it's pretty much just binomial expansion and taylor series to get to this point) $$ f(x...
The eigenvalues 𝜆1λ1, 𝜆2λ2 are calculated and utilized to compute the curve derivation R and similarity measure S. The curvilinear likeliness ℰE is given by ℰ(𝑥,𝑦,𝜎)=⎧⎩⎨ 0𝑒−𝑅2𝛽21[1−𝑒−𝑠2𝛽22]𝑖𝑓 𝜆2<0𝑜𝑡ℎ𝑒𝑟𝑤...
