Step by step
Solved in 3 steps
- The security scheme for IEEE 802.11, prior to 11i, was Wired Equivalent Privacy (WEP). WEP assumed all devices on the network share a security key. The purpose of the authentication scenario is for the STA to prove that it possesses the security key. Authentication proceeds as shown in Figure 24.13 What are the benefits of the authentication scheme? The authentication scheme is incomplete. What is missing and why is it important? What is a cryptographic weakness of this scheme?Suppose DNS transaction IDs were extended from 16 bits to 32 bits. Based on a "birthday attack" analysis (see the hint in #2 above, which is a brief explanation of this technique), how many DNS requests (each with 1,024 fake responses) would an attacker need to make in order to get a 50% chance of succeeding in a DNS cache poisoning attack?In our modern, internet-connected world, it is our mission to ensure that all parties involved in a conversation may do so in a secure manner. While this is going on, we make use of something called Named Data Networking, or NDN, to keep data packets secure while they are being developed (NON). Please provide a description of the data-centric security paradigm used by NDN.
- We now protect the Internet's communication infrastructure. While this is occurring, Named Data Networking is employed to safeguard data packets (NON). This article describes the data-centric protection paradigm of the NDN.Recall that the TCP/IP protocol suite's transport stage is where packet reordering and reassembly occurs. The Internet or the data layer are examples of lower tiers where a firewall may be used. How can a stateful inspection firewall tell whether a communication stream is broken or destroyed?We are now responsible for protecting the Internet's underlying communications infrastructure. When this is occurring, data packets are being protected by Named Data Networking (NON). Here, we detail NDN's data-centric security philosophy.
- What is the tunneling procedure? What are the three kinds of tunneling protocols?Financial institution debit cards are protected by personal identification numbers (PINs). Personal identification numbers (PINs) of this kind typically consist of four digits. Information supplied from ATMs to the computers that verify credit and debit card transactions is encrypted before transmission. A combination of ad hoc management techniques and encryption is necessary for financial organizations to keep data secure. Please provide some light on the reasoning for this prerequisite.Do not underestimate the complexity of DNS records; here are all the many sorts. Each one has to be broken down into its component parts in excruciating detail, with supporting examples from the actual world and a robust defense of its efficacy. Perhaps things might be made easier if a website's domain name and email address were the same.
- What is the tunneling process? What three kinds of tunneling protocols are there?What is the significance of encryption protocols like SSL/TLS in securing data transmission over the internet?Design a security protocol that will allow a Mutually Agreed Session key (Kabc) to be established between three entities A, B and C. This key can then be used to secure a chat between the three entities. I want you to develop your own design based on the conditions below.Note: The session key should NOT be known to the Chat Server (S) and the Chat Server (S) can only forward the encrypted messages to A, B and C and S cannot read the messages. The secure chat between entities A, B and C must use the Chat Server (S) and session key Kabc as below: (refer image)i.e. A, B and C Do NOT communicate directly. The following conditions apply to your protocol design.1. A, B and C Never communicate directly. 2. Each entity (A, B, C and S) have a Public Key Certificate, ie. CA<<A>>, CA<<B>>, CA<<C>> and CA<<S>>. 3. The Chat Server, S, has access to all Entity Certificates that use its service and can provide these Certificate to its service users if…
