Abstract

A digital signature verification system wherein a signature system may sign a conversational message, as might be used in a chat, instant messaging or enterprise instant messaging dialog, and a verification system may then verify the signature. The signature system may include a signing entity and a vault, wherein the signing entity provides the message and credentials and the vault creates the signature based on a first hash of the message that is further encrypted with a signature key. The verification system may include a validating entity and a verifier, wherein the validating entity provides the message, the signature, and assertions to the verifier and the verifier then forms a second hash of the message, uses a verification key corresponding with the signature key to decrypt the signature and obtain the first hash, and compares the two hashes to determine a proper validation response.
