Rsa Following Scheme Secure Provide Full Mathematical Explanation Attacked Bob Rsa Key Mod Q43798119
(RSA) is the following scheme secure? if not provide a fullmathematical explanation to why and how it can be attacked
Bob has an RSA key with modulo N with a size that isconsidered safe, 2048 and a public power of e=3 (shouldassure efficient encryption).
Alice wants to send Bob a big file, and chooses symmetricencryption: She uses a random k for AES and sends itencrypted using RSA using 
, and then sends the file encrypted by AES using key k
To decrypt the file, Bob recovers k using 
and then decrypts the encrypted file using AES with k asthe key.
NOTE: i know that it should be vulnerable to root cube attack, buti don’t understand why. it is not a secure scheme. please elaborateand explain. thank you very much
