Meet at the baseball field at three oclock Using a ROT3 cipher decrypt the following ciphertext. WKHF RUYH WWHL VUHG 2. Following are two problems using a rail fence cipher. Prove both of your answers by showing the steps involved in encryption/decryption. As [art of this problem you must also show the steps involved in reversing what you are being asked for. Using a rail fence cipher with a depth of 2 encrypt the following message:
The bird is a raven Reverse the steps to decrypt your answer and explain the steps. Using a rail fence cipher with zig zag pattern and a depth of 3 decrypt the following message:
MAEKN ETTHPRAOEM ETATP Reverse the steps to encrypt your answer and explain the steps. 3. This is a three part question. For each part the answer requires identifying an asymmetric encryption technique, hashing or both. As part of each question you need to discuss the technique to demonstrate your understanding of how the functionality (confidentiality, authenticity, integrity) is supported. You need to discuss the details of what the sender and receiver do and the key usage if applicable. What technique is used to exchange messages between two parties ensuring confidentiality? Discuss.What technique is used to exchange messages between two parties ensuring authenticity? Discuss.What technique is used to exchange messages between two parties ensuring integrity? Discuss. 4. Logical operations. Neatly align your result under the operands. Perform a logical AND on the following two binary strings:11101111011100101011101001 Perform a logical OR on the following two binary strings:11101111011100101011101001 Perform a logical XOR on the following two binary strings:11101111011100101011101001 5. How can hashing be used to ensure that a file you have copied from a website has been completely and accurately copied? You should consider techniques that are in current use today for copying images and other files from servers. Provide some details with your explanation.
