SPF uses DNS to publish the domains, subdomains and mail servers from which authorized email can be sent. DKIM uses DNS to advertise the public keys that can be used to authenticate email messages as having legitimately originated from the domain.

SPF, DKIM, and DMARC help authenticate email senders by verifying that the emails came from the domain that they claim to be from. These three authentication methods are important for preventing spam, phishing attacks, and other email security risks.

The difference between them, in a nutshell, is that DKIM attempts to verify whether mail is legitimate, and DMARC suggests what to do with mail that isn't legitimate. The technical details are more complicated, of course.

While they both are authentication protocols, SPF and DKIM are not exactly the same. SPF is used to authenticate the sender and ensure that only authorized servers can send emails from your domain, while DKIM is used to verify that messages haven't been tampered with in transit.
