Assuming the following IP header lacking checksum: 01000101.00000000.11000011.00101010. 00000000.00000000.00000000.00000000. 10000000.00000000.00000000.00000000. <- checksum 01100011.11011001.00000000.00000001. 10000000.00000000.00000000.00000010 Compute its checksumarrow_forwardI would like to know the features of BranchCache, Metadata, and LPR Port Monitorarrow_forwardPlease answer the JAVA OOP questions below: How do arrays of objects differ from arrays of primitive types? Why and when would you use an array of objects? What are the different ways to initialize an array of objects? What is a static variable in Java? How does its scope differ from instance variables? When should you use static variables? Provide examples where static variables are beneficial over instance variables. What is the difference between static and non-static methods in the Data Definition Class? What are the benefits of using static methods?arrow_forward
- Assume you are a loyal member of Costco. You have been expecting your membership reward from the company, and you just received a text message on your mobile phone. The message appears to be from Costco: Costco - Your 3% return is ready: costco.wholesaledividend.com Before clicking the link in the message, you consider whether this is genuinely from Costco or a phishing attack on you. How can you tell? If it is a phishing attack, what mechanism was most likely used to send the message to you? What actions can you take if you are not sure whether it is a genuine message from Costco? What actions can you take if you are sure this is a phishing attack?arrow_forwardRSA and Diffie-Hellman are important algorithms in public-key cryptography. What are the differences between the two? Assume you intercept the ciphertext C = 105 sent to a user whose public key is e = 7, n = 403. Explain in detail how you will find the private key of the user and crack the ciphertext. What is the plaintext M?arrow_forwardCBC-Pad is a block cipher mode of operation commonly used in block ciphers. CBC-Pad handles plain text of any length. Padding is used to ensure that the plaintext input is a multiple of the block length. Hence, the ciphertext is longer than the plaintext by at most the size of a single block.Assume that the original plaintext is 556 bytes and the size of a cipher block is 28 bytes. What will be the padding? If the original plaintext is an integer multiple of the block size, will padding still be needed? Why or why not?arrow_forward
