A: ANSWER:-
Step by step
Solved in 2 steps
- Attacks on a cipher that use letter frequency can be made more difficult by assigning multiple codes to the most frequently used letters in the alphabet. Such a cipher is called a homophonic cipher. Explain why multiple codes cause no increase in the time to decipher a message if the key is known.Describe the steps involved in mounting a statistical attack on a monoalphabetic substitution cipher. (please do not explain it with pictures) Explain why this approach would fail on a polyalphabetic substitution cipher?Affine cipher is less secure than caesar cipher. 1. true 2. false
- Develop a system (other than Substitution cipher, Transposition cipher, or Vigenѐre cipher) that you can use to encrypt and decrypt a certain message.Explain why attacks on a cipher are more difficult for a short message.Perform the Encryption using the Hill Cipher where the Plain text: "POH" and the key is: "GYBNQKURP".
- 45. Encrypt the message “success is not final, failure is not fatal” using a columnar transposition cipher for the given keyword “algebra” (1 6 5 4 3 7 2)..Briefly describe the RSA cipher. If the prime numbers e, p, and q are 17, 7, and 11, respectively, in the RSA technique, derive the public and private keys.Suppose that when a long string of text is encrypted using a Vigen`ere cipher, the same string is found in the ciphertext starting at several different positions. Explain how this information can be used to help determine the length of the key.
- A shorter message makes it harder to attack the cipher since it is easier to read.Q1: Secret Messages Implement a Caesar cipher to encrypt messages.Asymmetric ciphers are more secure because they use non-reversible procedures. This chapter introduced asymmetrical operations. If so, what are some asymmetric operations?
