Protocol Security) provides secure communication over IP networks through several essential functions. Let&#8217;s explain each function and its purpose:<br\/>1. Data Origin Authentication:<br\/>Description:The receiver verifies the identity of the sender.<br\/>This function ensures that the data received actually comes from the claimed source.<br\/>IPsec achieves this usingIKE (Internet Key Exchange)anddigital signatures.<br\/>TheAuthentication Header (AH)andEncapsulating Security Payload (ESP)support authentication.<br\/>Use Case:Verifying that a message claiming to be from a specific IP address is genuinely from that source.<br\/>2. Data Encryption:<br\/>Description:The sender encrypts the data, and the receiver decrypts the data.<br\/>Encryption ensuresdata confidentialityby transforming readable data (plaintext) into unreadable data (ciphertext).<br\/>Only the intended receiver with the correct decryption key can convert the ciphertext back to plaintext.<br\/>Common encryption algorithms used includeAES (Advanced Encryption Standard)andDES (Data Encryption Standard).<br\/>Use Case:Protecting sensitive data transferred over public networks.<br\/>3. Data Integrity:<br\/>Description:The receiver verifies received data to determine whether the data has been tampered with.<br\/>Ensures that the data was not altered during transmission.<br\/>Uses cryptographichash functions(e.g.,SHA-1, SHA-256) to generate amessage digest.<br\/>The digest is sent with the data and verified on the receiving side.<br\/>Use Case:Detecting any changes made to the data packet during transmission.<br\/>4. Anti-Replay:<br\/>Description:The receiver rejects duplicate data packets.<br\/>Prevents attackers from capturing packets and replaying them later.<br\/>Usessequence numbersto detect replayed or duplicated packets.<br\/>The receiver keeps asliding windowof sequence numbers to compare incoming packets.<br\/>Use Case:Blocking malicious actors from sending previously intercepted packets to disrupt communication.<br\/>Why This Mapping Is Correct:<br\/>The functions and descriptions are aligned based on the core concepts of IPsec and the roles they play in ensuring secure data transmission.<br\/>Each function addresses a specific aspect of security:authentication, confidentiality, integrity, and replay protection.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(11,this)' id='btn-11' value='See Answer'  \/><input type='hidden' id='questionType11' value='textarea' class=''><\/div><div class='watu-question' id='question-12'><div class='question-content'><p><strong>NO.168<\/strong> You want only his telnet stream to be able to access the server (address 1011.100).
