Computer Science Question

Complete the following problem as described below. You should submit a .zip file (Windows) if you plan to submit more than one file. This would be in Word format (Docx). Software tools are available via the CS Virtual Desktop environment. (Review the Canvas Files folder for details if needed.) This assignment must be submitted directly (upload) via Canvas.

Cracking a password can involve different schemes, which involve several different approaches and strategies. This usually includes database access with protected passwords. Serval classic approaches include data dictionaries, brute-force, and rainbow attacks. Although there are numerous tools such as Hextools and Hashcat, your job is to come up with a strategy that is based on a (subset) of industry-related software deliverables that address this security breach. Use the following parameters to guide you:

• A Conceptual Approach that should include a Problem Domain Statement (e.g. Government Security domain) and the associated requirements.
• Design Part1, which should include a Visual Representation Diagram such as UML, Use-Case, Logic Flow Diagram, or other pictorial views.
• Design Part2, which should include Pseudo- Code and your Algorithmic Process (i.e. algorithm). These can be combined.
• Implementation: Optional. Can include code snippet(s) such as Java, Python, JavaScript, etc., examples.

Your solution should also utilize a classic area of research and deployment: user authentication via keystroke recognition. Consider the following patterns:

1. Key-up/Key-down: The time it takes to release one key vs the press of the next one.
2. Key-down/Key-up: The overall time it takes to release the key pressure of the next consecutive key where the use of a two simultaneous key pattern can occur such as double ASCII (or Unicode) code is entered or two or more devices (independent standalone CPUs).
3. Wait-period: The time that it takes to press and release from one key to another, but has a longer period of time when compared to 1 or 2 (i.e. user/software may be waiting to complete or guess at a password w.r.t. a hash/technique).

Assumption 1: Password attempt must exactly match (stored) user password with respect to ASCII key code.

Assumption 2: There does not exist a software hack that can defeat this problem.

P-Code Example of Key Stroke Time Interval:

//determine the key time period with respect to a temporal interval threshold

timeInterVal := If ((Key_Up.miliSecMethod() && Key_down.miliSecMethod()) > .01)

{

Trigger := alarmMessage()

}
