Why Signed Pings Matter
We’ve been socializing the idea of digital signatures for pings for some time now, and have had to hone our arguments in the face of inevitable and understandable push-back we get in some quarters on this issue. On the one hand, there’s a clear value proposition to publishers who already have an established, verifiable brand. Signed pings convey the integrity and authority of the publisher with each ping submitted. In cases where a signature can be mapped to an established SSL certificate, already in use by the publisher for ecommerce or cryptographic features on their website, little needs to be done to enable these publishers to assert their ownership over submitted content.
