Ok Google: Please Publish Your DKIM Secret Keys

Matthew Green, a cryptographer and professor at Johns Hopkins University, writes: The Internet is a dangerous place in the best of times. Sometimes Internet engineers find ways to mitigate the worst of these threats, and sometimes they fail. Every now and then, however, a major Internet company finds a solution that actually makes the situation worse for just about everyone. Today I want to talk about one of those cases, and how a big company like Google might be able to lead the way in fixing it. This post is about the situation with Domain Keys Identified Mail (DKIM), a harmless little spam protocol that has somehow become a monster. My request is simple and can be summarized as follows: Dear Google: would you mind rotating and publishing your DKIM secret keys on a periodic basis? This would make the entire Internet quite a bit more secure, by removing a strong incentive for criminals to steal and leak emails. The fix would cost you basically nothing, and would remove a powerful tool from hands of thieves.
