How to implement elliptic curve cryptography(EDWARDS Curve) to my Topology

surya.prakash · 06-28-2014, 12:05 PM

Good Evening to all,

I am implementing "elliptic curve cryptography by using EDWARDS curve" to my Toplogy. I had got my Mobile Topology attached bellow, that i want to add Cryptography technique. Please can any one guide me to implement EDWARDS curve to my Mobile topology?

Thank you in Advance

This question is much too broad.

Yes sir, but in this case i need to implement Mobile Overlapped Topology with secured communication through elliptic curve cryptography by using EDWARDS curve

Thank you for quick replay

If you have to ask here about how to implement any kind of ECC, you're nowhere ready to try. You need to consult with a cryptographer and that's going to cost you $$$. There's no way around that; any attempt to not consult a cryptographer will almost certainly result in an insecure product.

In addition to that thought ... as a categorical statement, "do it yourself" implementations of cryptography, no matter how well-intentioned (or informative) they might be, are almost never preferable to using widely-accepted cryptographic protocols, and the libraries which implement them.

Granted, there is a moderate 100% chance that those libraries have been, if not "hijacked," then at least "weakened" by agencies such as #CLASSIFIED#, #CLASSIFIED#, or even #CLASSIFIED#, which spend far too much of our money to do such things. But I daresay that there's nothing that you can realistically do about that ... and, in the grand scheme of things, that's really not your true problem anyhow. If your implementation is going to be broken, then that break will probably not come from a weakness in the algorithm. No, it will come from "something else" in the grand picture ... most likely, key management.

Most crypto libraries allow for many different crypto algorithms to be used. (You could implement an "elliptic curve" driver, for instance, until you found that one already exists.) They focus their attention on keys, message integrity, and so forth. There's a reason for that.
