Question: Suppose you have to send a very important large file to a party via an insecure network, and without interactions. Assume that no parties share secrets, but the PKI infrastructure is in place (i.e. all parties know all other parties authentic public keys). Describe what existing cryptographic schemes you will choose, and how (e.g. in what order) you will use them, so that the resulting scheme is • efficient (does not require many exponentiations), • provably provides privacy (is indistinguishable against chosen-ciphertext at- tacks, or IND-CCA) and authenticity/integrity (achieves integrity of cipher- texts, or INT-CTXT). Describe what computational assumptions are required for such guarantees to hold for your scheme. It is OK if security relies on the random oracle model.
