The authentication affected by the use of an asymmetric crypto system and hash function is known as Digital Signature.

Here are the steps involved in this process:

1. The sender creates a message.
2. The sender uses a hash function to create a hash value of the message.
3. The sender then uses their private key (from the asymmetric crypto system) to encrypt this hash value. This encrypted hash is the digital signature.
4. The sender sends the message and the digital signature to the receiver.
5. The receiver uses the sender's public key to decrypt the digital signature back into the original hash value.
6. The receiver also uses the same hash function on the received message to create a hash value.
7. If both hash values match, the message is authenticated and hasn't been tampered with during transmission.
