Popis:	In a public-key threshold encryption scheme, the sender produces a single ciphertext, and any \(t+1\) out of \(n\) intended recipients can combine their partial decryptions to obtain the plaintext. Ad hoc threshold encryption (ATE) schemes require no correlated setup, enabling each party to simply generate its own key pair. In this paper, we initiate a systematic study of the possibilities and limitations of ad-hoc threshold encryption, and introduce a key application to scalable multiparty computation (MPC).
