Hi 1.i want to know how can i find the order of the generating point?i mean what can be the convention used for infinity while programming so that i can find generating point.

2.Is there any bound for the values of x-y coordinates while encoding the text message using koblitz method?or can it be any value which does satisfy the equation y^2%p=x^3+ax+b %p

3.Is the value of k used during encoding of text message to find x-y coordinates(koblitz method) is same as the value randomely generated by the sender to encrypt the message? or both are different?and should the value of k be less than value of p(number of fields)
