Can we encrypt data while enabling fine-grained access control, as is necessary to protect big, complex data? In this talk, we will survey how addressing this question led to new lower and upper bounds in information-theoretic cryptography and secret sharing, which in turn came from building new connections to communication complexity and private information-retrieval.
