Step 1
The purpose of the OAEP encoding operation is to provide a secure and efficient way to encrypt messages using asymmetric encryption algorithms. It aims to add randomness and padding to the original message before encryption, which helps to prevent certain types of Show more…

Encrypt the message ATTACK using the RSA system with n = 43 · 59 and e = 13, translating each letter into integers (where A = 00, B = 01, . . . Z = 25) and grouping pairs of integers. [By grouping in pairs, we mean separately encode AT (4 decimal digits), then TA (4 decimal digits), and lastly CK (4 decimal digits). So your encrypted string will have 3 sets of 4 decimal digits corresponding to AT, TA, and CK.]

Bob wants to send Alice an encrypted message, "BUFFALO." Suppose Bob encodes letters of the alphabet as follows. A = 01, B = 02, C = 03, ..., Z = 26. To encrypt the message, Bob uses an RSA cypher with public key (pq, e) = (55, 3). What is the encrypted message that Alice will receive? (Assume Bob encodes one letter at a time. Enter your answer using a fixed number of digits with a space between each encoded letter: 01 for 1, 02 for 2, ..., 09 for 9.)
