1. Gomti, the collection of rational numbers (more)

    Use of XOR accumulator

    I draw another schematics, the main part is like following.

    The first part of 240-127-120 (accumulator)

    Instead of a shift register and a set of xor gates, it only uses an accumulator and a single xor gate.

    The shift register was used because I had an idea of changing the shift register …

  3. SOS in OpenPGP

    I was not able to describe SOS itself accurately in ECC in OpenPGP by SOS.

    So, this article is to augument the explanation.

    SOS is a suggestion to OpenPGP implementations to address the zero removal/recovery problem. I know that implementations already handle it by adding zero recovary for Ed25519 …

  4. ECC in OpenPGP by SOS

    In this article, I try to explain a specific way to improve current (as of March 2021) situation of OpenPGP with regards to EdDSA and ECDH with modern curves.

    Specifically, I suggest a way to introduce SOS. But even if you won't introduce SOS methodology into your implementation of OpenPGP …
