A TransactionAuthenticator is an abstraction of a signature scheme. It must know: (1) How to check its signature against a message and public key (2) How to convert its public key into an AuthenticationKeyPreimage structured as (public_key | signaure_scheme_id). Each on-chain DiemAccount must store an AuthenticationKey (computed via a sha3 hash of an AuthenticationKeyPreimage). Each transaction submitted to the Diem blockchain contains a TransactionAuthenticator. During transaction execution, the executor will check if the TransactionAuthenticator’s signature on the transaction hash is well-formed (1) and whether the sha3 hash of the TransactionAuthenticator’s AuthenticationKeyPreimage matches the AuthenticationKey stored under the transaction’s sender account address (2).
