I have a question about multiplication of two points belong to elliptic curve. I know every think about adding and scalar multiplication but not about multiplication of two points. Is there any method for this?
The reason that I need this is that in paper "Attributed-based encryption for fine-grained access control of encrypted data", we need choose group G and then a point g as the generator of this group. Then in setup algorithm, we should calculate g to the power of t1, while t1 is a number. So it means that we should multiply g into itself for t1 times. If we choose an elliptic field, how could we do this multiplication?
