You are to encrypt a ciphertext using the permutation p : {0,134 {0,1}4 defined as p(x) = ~x, ie, toggle each bit (0 to 1 and 1 to 0). If you need an IV use 1010. If you need a nonce use 01. If the mode uses padding to handle arbitrary plaintext lengths, add 10* padding. If you need a counter, begin at 1. Encrypt the ciphertext 1110 1110 111 using ECB mode. Write four bits per box, with the final box possibly having fewer bits. Encrypt the ciphertext 1110 1110 111 using CBC mode. Write four bits per box, with the final box possibly having fewer bits. Encrypt the ciphertext 1110 1110 111 using CTR mode. Write four bits per box, with the final box possibly having fewer bits. Encrypt the ciphertext 1110 1110 111 using OFB mode. Write four bits per box, with the final box possibly having fewer bits.
