Hybrid encryptions are encryptions which use a combination of post-quantum and classic cryptographic algorithms for encryptions to address threats/risks posed by large scale fault tolerant quantum computers (LSFTQC) on the first stage of the coming p...

Fault tolerant quantum computers pose a real current risk/threat to the current digital infrastructure, because they can break all asymmetric encryptions (RSA, ECDSA, etc.) and implementations of symmetric encryptions, which use asymmetric encryption...

In this post we consider a simple method to check if TLS/SSH servers have post quantum or hybrid encryptions. Hybrid encryption combines classical and post-quantum (PQC) cryptography to offer a secure transition to a future with quantum computers, wh...

In this post we consider a simple way to derive/prove the “Fortune’s formula” (see [1]), also known as Kelly criterion (see [2]). If p -denotes a probability to win a bet (or trade, etc.), O -denotes decimal odds on a winning bet, L -denotes a share...
