Please define the concept of a challenge-and-response authentication system in your own words (CRAS). If passwords are so insecure, what makes this method of authentication so much better?
Step by step
Solved in 2 steps
- 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?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.An authentication challenge-response mechanism should be shown.With password protection, how much more secure is it?
- Techniques for challenge-response authentication need thorough justifications. Although it is safer than passwords, why?Define the term "authentication challenge-response system" and describe its purpose. A password-based system is not as safe as the one described here.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.
- The notion of challenge–response authentication must be understood. In what way is it more secure than a password-based system?The idea of a challenge-response authentication system has to be explained. Why does this method provide more security than others that need passwords?Describe the idea of an authentication challenge–response system. A password-based approach is not as safe as this one.
- An authentication challenge–response system may be described. Why is this approach more secure than a password-based method?Authentication is put to use for a wide range of reasons; what are some of the more typical examples? How do the various methods of authentication stack up against one another in terms of the benefits and drawbacks that come along with the use of each individual method?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?
