What is the purpose of authentication? Several forms of verification are explored, along with their advantages and disadvantages.

Explain challenge-response authentication and its operation. This method's advantages over password-based ones are unclear.

An authentication challenge–response system may be described. Why is this approach more secure than a password-based method?

What characteristics give biometric authentication its edge over other authentication methods?

Write a complete java program that will store the weekly sales data for a small shop that sells candles into two dimensional array of type double, the shop has five candle scents as follow: week 1 sales week 2 sales week 3 sales week 4 sales Candle Scent 1 41.41 23.33 4.09 1.20 Candle Scent 2 33.86 22.30 27.85 17.35 Candle Scent 3 8.58 7.97 0.61 28.39 Candle Scent 4 10.23 32.62 22.21 21.91 Candle Scent 5 43.16 12.57 20.33 2.40 Your program should calculate and prints the followings: Total sa for week 1 Total sales for week 2 Total sales for week 3 Total sales for week 4 Maximum sales with the week number and candle scent number was found. Minimum sales with the week number and candle scent number was found. Sample run: Total Sales of Week 1 = 137.25 Total Sales of Week 2 = 98.80 Total Sales of Week 3 = 75.09 Total Sales of Week 4 = 71.26 Maximum Sales = 43.16 found week 1 for candle scent 5 Minimum Sales = 0.61 found in week 3 for candle scent 3

Numerous benefits come along with the use of asymmetric encryption methods, such as public key cryptography.

Several symmetric and asymmetric ciphering techniques are used throughout the public key cryptography process.

Explain the meaning of the name of an authentication challenge-response system. In what ways does it provide a greater degree of security than a conventional system that uses passwords?

To better understand authentication, please describe what a challenge-response system is. How is it more secure than a system that requires you to enter a password?

Explain challenge–response systems in authentication. Is it safer than passwords?
