When using a MAC, an attacker attempts to alter both the Tag (the MAC) and the ciphertext (message authentication code). I'm scared of the potential consequences. If this attack succeeds, the target will always be able to spot a tampered Tag or ciphertext.
Assume that you want to make the message available to the users who are authorized to read the respective message. Each message contains some confidential data; therefore, instead of sending the plain text to each user, you decided to encrypt each message using secret key encryption and make the encrypted messages available for read. You need to distribute the encryption keys with the encryption methods to the authorized users. The communication channel between the users and the website is insecure; however, the pubic keys of the users are encrypted through double encryption methods for 2-layer of authentication mechanism and convert into cipher text as follows. The following cipher message was produced using the Rail Fence algorithm with 3 rails: “WECRLTEERDSOEEFEAOCAIVDEN” What is the corresponding plain text?What’s wrong with the shift cipher? Provide any three reasons.

Assignment Instructions Go to a popular online electronic commerce site like Amazon.com. Place several items in your shopping cart, and then go to check out. When you reach the screen that asks for your credit card number, right-click on the Web browser and select “Properties.” What can you find out about the cryptosystems and protocols in use to protect this transaction? Repeat step 1 on a different website. Does this site use the same or different protocols? Describe them.

15) If the form is submitted via GET request using HTTP, can a browser adversary (i.e., one who can locally observe the URLs requested by the user) obtain the password? True False 16) If the form is submitted via POST request using HTTP, can a network adversary obtain the password? True False
Because decrypting end-to-end encryption may be challenging, application proxies could have performance concerns. This is because end-to-end encryption is becoming more common. It is possible that a solution that provides a proxy server with the ability to engage via a secure protocol at the application level would be helpful to the proxy server.
