(20 pоints) A cоmpаny hаs sоftwаre for a symmetric key encryption scheme that is known to be IND-CPA secure under some reasonable assumptions. The message space is the set of bitstrings of arbitrary length. The company wanted to strengthen security and decided to use the existing software in the following way. Let's call the modified scheme . The encryption algorithm for a message encrypts it twice, i.e., computes the ciphertext as , for any . Here || denotes concatenation. Decryption algorithm decrypts both parts and makes sure the decryptions are valid and the same message. I.e., computes
