"Linux 5.3 will turn back getrandom() into /dev/urandom with its never-blocking behavior" Wait, what? Was getrandom crippled without me noticing? I can find an LWN thread but nothing definitive.https://twitter.com/NCCsecurityUS/status/1208021091920171009 …

You write: "the computational demands of SIKE out-weigh the reduced network traffic. Only for the slowest 5% of connections are the smaller messages of SIKE a net advantage." Applies also to net energy measurements with portable devices (my slides for ETSI workshop next week).pic.twitter.com/xxtXePtW3x
