Problem 1 (Authentication): Consider the following authentication protocol, which uses a classical cryptosystem. Alice generates

a random message r, enciphers it with the key k she shares with Bob, and sends the enciphered message {r}k to Bob. Bob deciphers it, adds 1 to r, and sends {r + 1}k back to Alice. Alice deciphers the message and compares it with r. If the difference is 1, she knows that her correspondent shares the same key k and is therefore Bob. If not, she assumes that her correspondent does not share the key k and so is not Bob. Does this protocol authenticate Bob to Alice? If so, Why? Otherwise, explain why not.

Answer:

Check the explanation

Explanation:

Yes, going by the question above, the protocol validates Bob to Alice for the reason that the key is only shared between Bob and Alice as well as the number which is being sent randomly. Therefore the invader won’t be able to predict and response to that number. Because of the authentication protocol, that makes use of a classical cryptosystem thereby resulting into the possibility of an argument such that key finding is attainable via invader.

Serhud [2]

Answer:

A varying infrastructure.

Explanation:

The competitive pressure it creates for multinational companies in the industry is one of difference in infrastructure because different technical standards are found in different parts of the world.

For instance, A technical standard known as Global Systems for Mobile (GSM) is common in Europe, and an alternative standard, Code Division Multiple Access (CDMA), is more common in the United States and parts of Asia.

Consequently, equipment designed for GSM will not work on a CDMA network and vice versa as a result of varying infrastructure, so companies would be innovative in order to improve on their products.

You speak to a business owner that is taking in almost $2,000 in revenue each month. The owner still says that they’re having tr
Serga [27]
Let's say for example that the business is taking in $2000 of revenue.  That is the amount that the business collected for it's services - like for fixing the computer.  What if though it costs $500 for the equipment (that's an expense).  Now they only made $1500.  Now the customer complains and says that the computer isn't fixed properly so the company sends out a techie for 2 additional hours.  They need to pay their employee (another expense).  Now the $1500 is down to $1400.  They would have utilities to keep their lights on and insurance and many other expenses.

Your profit looks like this:
Profit = Revenue - Expenses

Assume your sketch has a variable named silo, which stores an object that is defined by a class you have created. The name of th
yulyashka [42]

Answer:

c. let v = silo.volume();

Explanation:

When you create and initialize a new object you pass through that object's class constructor. The constructor is in charge of initializing all the necessary variables for that class including radius and height. Once you save the object in a specific variable (silo) you need to call the class methods through that variable, using the '.' command. Therefore, in this scenario, in order to call the volume() method you would need to call it from the silo object and save it to the v variable, using the following statement.

let v = silo.volume();
