Proof of possession (PoP) is a cryptographic property and protocol mechanism that demonstrates a party controls a private key associated with a claimed public key or credential, without exposing the private key itself. Expanded Explanation 1. Technical Function and Core Characteristics Proof of possession establishes that an entity can generate a valid cryptographic response, such as a digital signature, using a private key that corresponds to a presented public key or certificate. It prevents

What we add

Counted facts

A dictionary definition doesn't say how often a term is actually used. This counts it across the graph -- articles that mention it, open source projects tagged with it, and the organizations tagged with it, listed here alongside the count. A term has no peer companies, and nothing here claims otherwise.
