Private quantum channels, random unitary channels and tamper resistance

We study a specific security property of private quantum channels - ability of the adversary to modify the plaintext in a deterministic way using only operations on ciphertexts (tamper resistance). We also study relation of quality of encryption and quality of tamper resistance on random unitary channels.
