is a randomized encryption scheme, but we could also consider defining it as a nonce-based scheme, interpreting r as the nonce: Enc(k, r, m) = (r, F(k, r))
Added by Patricia B.
Step 1
The encryption function outputs a tuple (r, F(k, r)), where F is a deterministic function that takes the key k and the nonce r as inputs. Show more…

Consider the following encryption scheme where M = {0, 1, ... , 9} = C; K = {0, 1, ⋯ , 11} and: • Gen produces a uniformly random key in K. • Enck (m) = m + k (mod) 10 • Deck (c) = c − k (mod) 10. Prove the encryption scheme is not perfectly secure.

We consider the RSA encryption scheme with a public encryption key (e, m) = (23, 2623). Find the private decryption key d.

Suppose F_(k )is a PRF and it outputs n bits. We define a symmetric key encryption algorithm as follows: The plaintext m is with length 2n, when encrypting m, the algorithm chooses a random r, computes F_(k ) (r) and obtains y. The algorithm then computes (y||y)⊕m (where ⊕ stands for the XOR operation), i.e., using y to mask both the first half and second half of the message. Is such encryption algorithm IND-CPA secure? Briefly explain.
