Describe the concept of a system that verifies users with a challenge and response (CRAS). What distinguishes this approach from others that rely on passwords as being more secure?
Step by step
Solved in 3 steps
- Define "authentication challenge–response system." Why is this approach safer than password-based ones?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?In the challenge-response system, distinguish between the challenges and replies that are being employed. What makes it more secure than a password-based technique is not immediately apparent.
- Explain the practical use of a challenge-response authentication system.How does it make a system that needs a password to access it any less secure?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?Display an authentication challenge-response mechanism. Why is it safer than passwords?
- Challenge–response authentication techniques need detailed explanations. It's more safe than passwords, but why?It is important to explain how a challenge–response authentication system works and how it functions. It is not immediately clear why this is the case, despite the fact that it gives the impression of being more secure than a conventional system based on passwords.Describe the idea of an authentication challenge–response system. A password-based approach is not as safe as this one.
- 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.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 challenge response authentication system (CRAS) is a system that utilises a question and its corresponding answer to authenticate users. This system is designed to verify the identity of users by posing a challenge question and requiring the user to provide the correct response. What is the comparative level of security offered by this authentication method in contrast to a password-based approach?
