Abstract

In all existing encryption systems, the owner of the master secret key has the ability to decrypt all ciphertexts. In this work, we propose a new notion of pre-constrained encryption (PCE) where the owner of the master secret key does not have "full" decryption power. Instead, its decryption power is constrained in a pre-specified manner during the system setup. 
We present formal definitions and constructions of PCE, and discuss societal applications and implications to some well-studied cryptographic primitives.
