May I ask a question about the key generation protocol? #78

Closed yepp4you closed 4 years ago

yepp4you commented 4 years ago

4.1 Key generation protocol in GG18spec is as below.   values Xi = g ^ xi are public. But is the code only modulo? round.save.Xi = new (big.Int) .Mod (xi, tss.EC (). Params (). N)

round.save.Xi is not public. What you're referring to (X_i = g ^ x_i) are known as BigXi in the code.
