Where does snow fall to create an avalanche? When using preexisting block ciphers, how do you generate the avalanche effect? Justify your claims with examples.

Perform encryption and decryption using the RSA algorithm for the letter "S". Show all steps in details when p=5 , q=7 , e=5.

Perform the Encryption and then the Decryption for the Hill Cipher where the Plain text: "POH" and the key is: "GYBNQKURP".

Where does snow fall to create an avalanche? When using preexisting block ciphers, how do you generate the avalanche effect? Justify your claims with examples.

Where does an avalanche get its start? How can the avalanche effect be generated in the block ciphers that are already in use? Provide an example to explain your idea.

The security of asymmetric ciphers is based on the asymmetric operations, meaning operations that can not be easily reversed. What kind of asymmetric operations have you learned from this chapter? Can you propose some asymmetric operations?

Use the RSA cipher with public key n = 713 = 23 · 31 and e = 43 to decrypt the ciphertext 675 089 089 048 and find the original messages. Consider d=307 and Performs all steps show all the step on how you solved it use pencil and paper. dont use AI

Let's encrypt a message using RSA: Choose p = 7 and q = 11, and then select e=13. a.Compute d b.Select plaintext message x=7. Produce the ciphertext y using the fast exponentiation algorithm. c. Decrypt the ciphertext (y) to verify that the initial plaintext (x) is produced. Again, please use the fast exponentiation algorithm.
