Re: [Ace] on signature verification times for sec192r1

I fully agree...

J3A081M  can be found at 10$ over the WEB

Futhermore this class of cheap device can process TLS or DTLS as

https://tools.ietf.org/html/draft-urien-uta-tls-dtls-security-module-00

They could be used for numerous applications in the IoT
