Ten of the proposed 12 amendments were ratified by three-fourths of the state legislatures on December 15, 1791. The ratified Articles (Articles 3–12) constitute the first 10 amendments of the Constitution, or the U.S. Bill of Rights. In 1992, 203 years after it was proposed, Article 2 was ratified as the 27th Amendment to the Constitution. Article 1 was never ratified.

DeVry SEC 280 Week 3 Exercise latest

You installed Cryptool version 1.4.31 in Week 2. If you uninstalled Cryptool, you will need to reinstall the software as you did in Week 2. Follow the same instructions from unit 2 to open Cryptool. Click on File from the top menu bar and select New. Type This is a test.at least five times. Click on Encrypt/Decrypt from the top Menu Bar. Select Asymmetric encryption. In the pop-up window, select the only option available (this is a user profile)—SideChannelAt……. Click on Encrypt. The RSA-encrypted text will be displayed. Capture the screen and paste it in the Word template called Week 3 Template.docx.

In the next step, you are going to create a key pair. Note that asymmetrical encryption uses a key to encrypt (public key) and another key to decrypt (private key). Click on Digital Signature/PKI from the top menu bar and select PKI. Now choose Generate/Import keys.Complete the pop-up template. Select RSA and 1024 for Bit Length. Complete the User Data section on the right. Remember to select a PIN because every time you decrypt, you will need the PIN to have access to your PIN. Capture the completed pop-up window and paste it in your template. Click on Generate new key pair. Close the pop-up window. Now click on Encrypt/Decrypt and select Asymmetric Encryption. You will see your profile in the list of recipients. Capture this screen and paste in your template. This profile will be used in Week 4. Close the pop-up window.

Click on Encrypt/Decrypt and select RSA demonstration. RSA uses two prime numbers to generate the public key and private key.Enter a prime number (e.g., 13) for p and another prime number for q (e.g., 7). Now capture the screen and add it to your template.Notice your RSA modulus is 15. Click on Alphabet and number system option. Select Specify alphabet. Select Normal in RSA variant. Select Decimal in Number System. Now enter a message in the input row “This is a test.” Click on Encrypt. Click OK on the pop-up message. Now capture this screen and paste it in your template.

Exercise – Keys

In this assignment, you will use Cryptool to generate encryption keys (if you deleted your earlier one, you will need to generate another one), sign a document, verify a signature, and extract a signature. Before we continue, let’s recap how a signature works. A document has a unique hashed value. The hash value can be encrypted with an individual’s private key to tie the document to the holder of the private key. The encrypted hashed value is called signing a document.

To start this exercise, open Cryptool (installed in Week 2). Click on File and Open. In the open window, type the following message: “It is a great day at DeVry University.” Click on Digital Signature/PKI from the menu bar. Select Generate/Import keys. In the pop-up window, select RSA and complete the User Data portion on the right panel. Select a PIN. I recommend “1234” for now. Click on Generate new key pair at the bottom of the screen. You will receive a message that the keys were generated successfully. Close any open windows except the windows with our message: “It is a great day at DeVry University.” Now, select SHA-1 (160 bits) for hash function and choose RSA for signature algorithm and now select your key pair from the bottom pane. Remember to enter your PIN (1234). The digital signature will be displayed in another window. Capture this screen and paste it in the Week4_Template.

Leave the signature page and click on Digital Signature/PKI and click on Verify Signature. Select the key pair and click on Verify Signature. You will get a message that the signatures are correct. They have to be because we just created the signatures. Capture the Signature Verification page and paste it in your Week4_Template. Now click on Digital Signatures/PKI and Click on Extract a Signature. A pop-up window will be displayed with the extracted signature. The signature and the signed message are displayed.Capture the page and paste it in the Week4_Template. Close all open Windows.

Now, create a text file in your document folder on your PC (save it as MYTEST.txt). This text document can contain any you would like and can be created using Notepad. Back to Cryptool, click on Digital Signatures/PKI. Select Signature Demonstration. The pop-up will contain a diagram of a schematic of the digital signature process. Click on Open document. Select the text document you created earlier. Click on Select Hash function. Choose SHA-1 and then click on OK. Click on Compute hash value and click on Hash value. The hash value of your file will be displayed at the bottom of the window. Now click on Generate key. Click on Generate Primes (accept default values) and Accept Primes. Click on Store Key. Now click on Encrypt Hash Value. Click on Encrypted Hash value. The Encrypted Hash value will be displayed at the bottom of the window. Now you are going to click on Provide Certificate.Enter your first and last name and a PIN (confirm the PIN). Click on Generate Signature. The signature will be displayed at the bottom of the window. Now click on Store signature. Capture the display screen and paste it in your Week4_Template. Click OK and close Cryptool.

DeVry SEC 280 Week 6 Exercise latest

For this exercise, you are going to start with this site: http://botlab.org.BotLab is a platform at the University of Washington that continually monitors and analyzes the behavior of spam-oriented botnets. There are many other locations on the Internet that keep real-time activities of botnets across the globe. My recommendation is to use your favorite search engine and search “real-time botnet tracking” and you will hit many results on botnet tracking. Using the information you found, develop a five-slide PowerPoint (seven bullets minimum per page) to describe the status of botnets in the world.
