- Data Encryption Standard Perform a Data Encryption Standard encryption on the plaintext (PL) by using key (K). The PL is your first 8 characters of your name and K is the last 8 digits of your student ID. For example: Name: Siti Fajar Plain text (PL): SITIFAJA Student ID: 201908040016 Key (K): 08040016 Show detail step by step involved.Using Columnar transposition encrypt the message “I HAVE LEARNED ABOUT DATA PROTECTION ", using key SECURE. Write the cipher in space provided below:Asymmetric - uses one key for encryption and another totally different key for decryption choose one: true false
- Perform a Web search for “Announcing the Advanced Encryption Standard (AES)”. Read this document, which is FIPS 197 standard. Write a short overview of the development and implementation of this cryptosystem.Name courses : data security Decrypt ciphertext obtained from aSubstitution Cipher. Note that there may be meaningless words at the beginning or at the end since the plaintext is divided into equalparts.

- Course Title: Computer and Cyber Security I need this questions answer as soon as possible. Questiton: Apply Playfair cipher to encrypt the message “the key is hidden under the door pad” using “friday” as a key (Ignore the space between the words).If the key with parity bit (64 bits) is 0123 ABCD 2562 1456, find the first round key note: this is question is from cryptography courseAssume the Public Key E=7 and N=35, encrypt the letter 'C' using RSA and write down the corresponding ciphertext in the answer field. Note: Just write the ciphertext in decimal. Do not write the computation process or anything else. Answer:
- Specify the components of encryption algorithm.OCTAVE SCRIPT Design a Knapsack public key cryptosystem, using this system, encrypt the plaintext "BHP". Show the details of the design process (give the selected values with explanation why selected them) and encryption process. Include in your answer Octave codes used. Use the ASCII or Unicode code to convert the plaintext characters to numbers. Finally, show how to decrypt the obtained cipher values to get the plaintext character back.Each letter in the cryptarithm represents one of the digits 0 through 9. Determine which digit is represented by each of the letters in the given cryptarithm. (Do not duplicate the number)
