Solved in 2 steps
- Explain how an authentication system that relies on a challenge and a response works. It is not immediately obvious how this new technique offers a higher level of security compared to the standard approach of using passwords.Is there a particular application for the authentication process? Which authentication techniques have the most benefits and disadvantages?Is there a particular application for the authentication process? Which methods of authentication provide the greatest benefits but also come with the most drawbacks?
- Is there a method that can differentiate between the benefits and drawbacks of the many authentication systems that are available?The operation of an authentication challenge–response system should be described. Although it seems to be more secure than a standard password-based system, it is not immediately evident how this is the case.Explain challenge-response authentication and its operation. This method's advantages over password-based ones are unclear.
- An authentication system that uses challenges and responses should be described in detail. What makes it more safe than a system that relies on passwords?The idea of a challenge-response authentication system has to be explained. Why does this method provide more security than others that need passwords?What is the authentication process's eventual goal? Which authentication techniques have pros and cons?
- In what sense do you understand the term "the purposes of authentication"? Compare and contrast both the positive and negative aspects of the various authentication schemes.Explain the idea behind an authentication challenge–response system in more detail. Why is this system more safe than one that is dependent on the use of passwords?Systems for challenge-response authentication must be well described. What makes it more secure than a password-based approach is not immediately obvious, but it does.
