can you solve the following using distributed point functions: - There are two servers S0 and $1. There are C clients. Each client holds a string alpha i in {0, 1}^n. The servers want to learn the number of clients who hold a certain string sigma. At the same time clients would like to keep their strings a secret. 1. Write a protocol that allows the servers to calculate the number of clients who hold sigma (while learning nothing about the client's secret string). 2. Prove the correctness of your protocol.
