==Properties== <!-- important information on the protocol: parameters (threshold values), security claim, success probability... --> This scheme has the following properties: *'''Correctness''': The scheme includes syndrome and correction functions and is thus robust against a certain amount of noise, i.e. below a certain noise threshold, the decryption circuit outputs the original message with high probability. *'''Ciphertext Indistinguishability''': This notion implies that an adversary, given a ciphertext, cannot discern whether the original plaintext was a known message or a dummy plaintext <math>0^n</math> *'''Certified Deletion Security''': After producing a valid deletion certificate, the adversary cannot obtain the original message, even if the key is leaked (after deletion).
