Consider a blockcipher $\mathsf{B}:\mathcal{K}\times\{0,1\}^n \rightarrow \{0,1\}^n$ with $|\mathcal{K}|=N$ for which we choose a secret key $K\in\mathcal{K}$ uniformly at random. Tick the \textit{correct} assertion.
A. If $\mathsf{B}$ is secure against known-plaintext decryption attack, then it is surely secure against ciphertext-only key recovery attack.
B. If $\mathsf{B}$ is secure against known-plaintext decryption attack, then it is surely secure against chosen-ciphertext decryption attack.
C. It is possible to recover $K$ with precomputation: $O(N^{2/3})$, memory: $O(N^{2/3})$, time: $O(1)$.
D. It is possible to recover $K$ key with precomputation: $O({1})$, memory: $O(N)$, time: $O(1)$.

Consider two distributions $P_0,P_1$ with the same supports and a distinguisher $\mathcal{A}$ that makes $q$ queries. Tick the \textit{incorrect} assertion.
A. When $q=1$, $\mathsf{Adv}(\mathcal{A})\leq d(P_0,P_1)$ where $d$ is the statistical distance.
B. When $q>1$, $\mathsf{Adv}(\mathcal{A})\leq \frac{d(P_0,P_1)}{q}$ where $d$ is the statistical distance.
C. When $q=1$, the strategy ``return 1 $\Leftrightarrow \frac{P_0(x)}{P_1(x)}\leq 1$'' achieves the best advantage.
D. To achieve good advantage, we need to have $q\approx 1/C(P_0,P_1)$ where $C$ is the Chernoff information.
