Abstract
Systems and methods for zero trust authentication. In certain embodiments, a method may comprise providing, from a client computing system to an identity provider (IdP) authority, an authentication nonce value generated by hashing a random value and a public key of the client computing system, and receiving, at the client computing system from the IdP authority, an authorization token including the authentication nonce value, where the authorization token is signed by a private key of the IdP authority. The method may further comprise providing a message including the authorization token from the client computing system to a target computing system via an intermediary co-signer (ICS) configured to authenticate the message.
