Dear,
may someone can do better understanding, but this is report about
post-quantum cryptography, not about current cryptography usage.
I not sure what has been changed from a past, but I learned that quantum
attack require this numbers of qbits (I used the same strenght):
RSA, Rabbin, DH - 2x key size (this mean 2kb key require 4kqbits)
ElGamal - 3x key size (this mean 4kb key require 12kqbits)
ECC - 6-8x key size (this mean 224b key require 1344qbits – 1792qbits)
‘m I true?


More, there should be (I don't know current situation well) also
assumption about number of quantum gates to provide appropriate
computing power. This is not a small, formula has been 72*qbits^3

 

There is significant evolution in near past, but I afraid that we are
years from successful implementation. From other point, the quantum
computing contest has been started and I think that paper only explain
why this competition are required.

 

Regards

 

Jan
