Protecting Against DKIM Replay - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240113893 titled 'Protecting Against DKIM Replay
Simplified Explanation
The abstract describes a method for securing messages by verifying the authenticity of the message and its intended recipient through a DNS TXT record delegation policy.
- Obtaining a message with a digital signature and list of recipients from a message server.
- Checking the DNS TXT record for a delegation policy indicating all intended recipients.
- Validating the digital signature and confirming the user as a declared recipient.
- Indicating the message is authentic if the signature is valid and the user is a declared recipient.
Potential Applications
This technology could be applied in secure messaging services, email encryption, and digital communication platforms.
Problems Solved
This technology solves the problem of verifying the authenticity of messages and ensuring they are delivered only to intended recipients.
Benefits
The benefits of this technology include enhanced message security, protection against unauthorized access, and increased trust in digital communication.
Potential Commercial Applications
Potential commercial applications of this technology include secure messaging apps, email encryption services, and data protection solutions.
Possible Prior Art
One possible prior art could be end-to-end encryption methods used in messaging apps to secure communication between users.
Unanswered Questions

Original Abstract Submitted
a method for securing messages includes obtaining, at a first message server, a message for a user of a message service hosted by the first message server, the message including a header including a digital signature signed by an author of the message and a list of one or more recipients of the message. the method includes determining that a domain name system (dns) txt record associated with the message includes a delegation policy indicating that a second message server declared all intended recipients of the message. in response, the method includes determining that the digital signature by the author is valid and that the user is a declared recipient of the message. the method includes, in response to determining that the digital signature by the author is valid and the user is the declared recipient of the message, indicating the message is authentic.
