Ron Rothblum @ TAU on the circular security of bit-encryption

Motivated by recent developments in fully homomorphic encryption, we consider the folklore conjecture that every semantically-secure bit-encryption scheme is circular secure, or in other words, that every bit-encryption scheme remains secure even when the adversary is given encryptions of the individual bits of the private-key. We show the following obstacles to proving this conjecture:
