Not my blog. Author works on a backup/archival tool called "Asuran", which I assume motivates a lot of the research into AEAD. I had never heard of the "partitioning oracle" attack, which is a really interesting way to exploit Poly1305 tags under certain conditions. I never would have assumed that it's practical to generate multiple ciphertexts that all authenticate under the same Poly1305 tag. That property leads to some interesting attacks.
