4-bit Block Cipher

Suppose that our block cipher, when keyed with our symmetric key, maps plaintext blocks to ciphertext blocks according to the following table (values are hex): Plaintext --> Ciphertext 0 --> C 1 --> 7 2 --> F 3 --> 3 4 --> 9 5 --> 2 6 --> 4 7 --> 8 8 --> E 9 --> 5 A--> D B --> 6 C --> 0 D--> 1 E --> B F --> A 1. Encrypt the message Ox0A1 in ECB mode using the 4-bit block cipher given above. OXF6B OXCD7 Ox32F Ox01A 2. ECB Mode Decryption Suppose you have a 4-bit block cipher that, with our secret key k, encrypts input blocks to output blocks according to the permutation in Table 1. Decrypt the 16-bit ciphertext "0x2AAB" in ECB mode using this cipher. Show your work
