It reduces the attack surface, since the client device can connect to the entropy-gathering device with considerable assurance (it can be configured with a pinned CA or PSK, etc), and at startup can use some entropy saved from the previous run. An attacker in a privileged position could try active attacks like a DoS against the connection to the entropy server, but a (more dangerous) passive attack looks very difficult. And it's practical for real-world data centers; implementation and equipment costs are low. It should even be possible to do this with one of those SOHO WIFi routers that have USB ports and media-sharing features, for use by smartphone apps and the like. -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
