Suppose the following table denotes the encryption permutation of Permutation Cipher for 8-byte blocks. 1 4 2 6 X PI(X) 1 3 Here, in each column with "i" in the first row and "j" in the second row, it means that "the ith byte of ciphertext is the jth byte of plaintext". Give the decryption permutation table. In the table, in each column with "i" in the first row and "j" in the second row, it means that "the ith byte of plaintext is the jth byte of ciphertext". Decrypt the following ciphertext (each 8-byte block is encrypted separately): TGEEMNEL NNTDROEO AAHDOETC SHAEIRLM 3 6 4 2 5 7 7 8 8 5
