Step by step
Solved in 3 steps with 2 images
- Using Columnar transposition encrypt the message “TODAY IS MIDTERM EXAM OF INTRODUCTION TO SECURITY ", using key LEMON. Write the cipher in space provided below:Encrypt the given plaintext using Caesar cipher, and write down the corresponding ciphertext in the space provided below. Plaintext: THE SEMESTER IS SHORT Note: Write the ciphertext in CAPITAL LETTERS without spaces. Just write the ciphertext in the answer field, nothing else.Perform the Encryption using the Hill Cipher where the Plain text: "POH" and the key is: "GYBNQKURP".
- Encipher the following plaintext using the Caesar cipher and key = 5: “meet me at the park”Decrypt the message “HDSIOEYQOCAA” using 3*3 Hill cipher with the Key: “CIPHERING”. Encrypt the text decrypted above using Columnar Transposition cipher with key- “BENIGN”. Also comment on the differences observed in the two ciphering techniques used.Encrypt the plaintext “CAT” using the following RSA model if A uses P = 11 and Q = 19 whereas B uses P = 13 and Q = 17. Then Decrypt the cipher to get back the plaintext.
- Using Shift Cipher with Key = 4, encrypt the plaintext CONFIDENTIALITY ISASSUREDUsing Vigenère Cipher, decrypt the given cipher text “PNDSRX DLSCWXT” and find its plaintext. The secret key is “basket”. Consider the space between the two words of cipher text.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?
- 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.Based on One-Time algorithm, if we have used Uppercase, space, ., and ? Now the plaintext “THERE ARE TWO TYPES OF ENCRYPTION.” has been encrypted to “MLBKMILOQBXMLQEHAVGLHCCSB?GPDXFLKZ”.Use the same key to encrypt the word “ENCRYPTION”.Please answer unicity distance question Calculate H(K), H(M) and H(C) and the unicity distance for the following cryptographic system: First encrypt your plaintext using (a) a Vernam cipher with key lengths 5 and 7. and then encrypt the cyphertext by (b) 2 x 2 Hill cipher mod 29 The cypher system is the combined cypher of (a) and (b).
