The Kerberos Authentication Server might reject an AS_REQ message and instead require pre-authentication - that is, it requires the client to send a timestamp encrypted with the client key. Why does it do this? Select one: a. It must not disclose the Ticket Granting Ticket before the client has authenticated b. It is dangerous to respond to an AS_REQ message before the client has authenticated c. Responding to multiple AS_REQ messages would allow a guessed plaintext attack d. It needs the client's public key to check the pre-authentication message was signed correctly

must answered ALL parts for upvote, as per chegg guidelines, up to four subparts may be answered: - what are two desirable properties of IV in network security? - a cryptographic hash function is used to provide confidentiality and integrity of a message, true or false? - when AES is used with the CBC mode, the size of an IV is 256 bit long, true or false?
Consider the following simple authentication dialogue: C → AS: IDc II Pc II IDv AS → C: Ticket C → V: IDc II Ticket; Ticket = E(Kv, [IDc II ADc II IDv]) Where: C = client AS = authentication server V = server IDc = identifier of user on C IDv = identifier of V Pc = password of user on C ADc = network address of C Kv = secret encryption key shared by AS and V ***Explain the process of this protocol.
Use built-in authentication and authorization services on the web server when a client requests access to restricted data. Which of the following two justifications for layered protocols do you find more convincing? Don't just make a claim without any evidence.
Adaptive Authentication is achieved by which of these combinations?
In Zigbee networks, which data fields are encrypted to ensure both the confidentiality and the integrity of the messages? Is/are there authentication performed on a particular data field or fields? Either before or after the actual encoding of the message, the message integrity code is created.
It would appear that once the DHCP Offer message is received, that the client may have all of the information it needs to proceed. However, the client may have received OFFERS from multiple DHCP servers and so a second phase is needed, with two more mandatory messages - the client-to-server DHCP Request message, and the server-to- client DHCP ACK message is needed. But at least the client knows there is at least one DHCP server out there! Let's take a look at the DHCP Request message, remembering that although we've already seen a Discover message in our trace, that is not always the case when a DHCP request message is sent. Locate the IP datagram containing the first DHCP Request message in your trace, and answer the following questions. 10. What is the UDP source port number in the IP datagram containing the first DHCP Request message in your trace? What is the UDP destination port number being used? 11. What is the source IP address in the IP datagram containing this Request…
Q9B- Context- Alice and Bob are members of the same Kerberos realm. They are both currently logged in with active session keys from the Kerberos KDC (key distribution centre). As per the Kerberos standard, the KDC has created unique session keys for both Alice and Bob, and then discarded them once received by the respective users. Alice wants to access a resource owned by Bob and contacts the KDC to request the necessary material. Answer the following questions about this scenario: Q- How can the KDC verify Alice’s identity after discarding her session key?
q9c- Context- Alice and Bob are members of the same Kerberos realm. They are both currently logged in with active session keys from the Kerberos KDC (key distribution centre). As per the Kerberos standard, the KDC has created unique session keys for both Alice and Bob, and then discarded them once received by the respective users. Alice wants to access a resource owned by Bob and contacts the KDC to request the necessary material. Answer the following questions about this scenario: Q- When Bob receives the service ticket from Alice, why should he trust her and what guarantees the service ticket is genuine and wasn’t forged by Alice?
When web clients want access to protected resources on a web server, native authentication and authorization services must be shown. Do you have any more?
5, For the first mode of Message Authentication code (MAC), which description is NOT correct? The key used in this mode is for message encryption. This mode cannot protect message confidentiality. The receiver is able to detect malicious message modification by checking the MAC. The attacker who does not know the key cannot calculate the MAC.
Use built-in authentication and authorization services on the web server when a client requests access to restricted data. In favor of layered protocols, which of the following two reasons do you find more convincing? To prove your claim, please provide specific instances.
For a web client to get access to a web server's restricted data, the client must first use the server's built-in authentication and authorization features. Besides these, are there any other advantages of use layered protocols? You should include instances to back up your arguments.
