Hi Pascal, Thanks for the information. Could you please explain what is nb_bloc_512bits?

I'd actually look at the A7xxx series of chips as they're designed to be embeddable. I've become a big fan of javacard style solutions over the years. In any event, the number of relatively inexpensive public key crypto accelerator chips (e.g. googl for "secure authentication chips") is greater than zero and continues to climb. And for not a lot of money. Estimating what from prices on Digikey, I'd think something less than $.50 for Quantity large as of today and half that or less in 1-2 years as its gets bundled into the "Swiss Army Knife" style of process (e.g. support for wireless 900mhz plus ... plus ... plus ... plus security...) (google for iot module secure element 900mhz for example). Later, Mike The performances with the curve secp192r1 are the following (for ECDSA + SHA1) Sign = 40ms + nb_bloc_512bits x 3.5 ms Verify = 60ms + nb_bloc_512bits x 3,5 ms By the way this chip has enough crypto ressouces for processing TLS or DTLS Rgs Pascal _______________________________________________ Ace mailing list [email protected]<mailto:[email protected]> https://www.ietf.org/mailman/listinfo/ace _______________________________________________ Ace mailing list [email protected]<mailto:[email protected]> https://www.ietf.org/mailman/listinfo/ace ________________________________________________________ The contents of this e-mail and any attachments are confidential to the intended recipient.
