Is a FEATURE REQUEST?:

I want to use the map relation in CL:

Reading the paper : image

By referencing your repository code in https://github.com/getamis/alice/tree/master/crypto/homo/cl, I want to follow yout construction to build an CL encryption, in my implementation, i need a map relation like CL15 C(OΔp^2) to C (OΔk), but in your repo i do not find its implementation.

How can I achieve my goal?

Hi XinwenXiang,

We do not implement this part. If we have time, we will complete it! There is a paper which maybe help you.

thanks for your answer, i found https://gite.lirmm.fr/crypto/bicycl. It seems that this library has implemented this part. I will read the paper later ：）
