boneidol: I just read S.S. Al-Riyami and K.G. Paterson, Certificateless public key cryptography 2003 https://web.archive.org/web/20181222114112/http://eprint.iacr.org/2003/126.pdf The math is not too complicated, but I find the notation a pain. Also, all the fuss over the group operation being additive in G_1 and multiplicative in G_2 seems such a faff. #math #crypto

rozzin: @boneidol The signature-flooding attack on the SKS #keyservers (and DoS of their users) is bad but doesn't actually sound like any kind of #apocalypse, and has basically nothing to do with the #WoT; signature-chains maybe, but that's something else entirely. !crypto
