Hello, if you have any need, please feel free to consult us, this is my wechat: wx91due
Objective:
- To provide an opportunity for students to apply computer security application concepts to a real case.
- To encourage teamwork and cooperation among students in the same group.
Background:
- Though there are many popular and strong encryption/hash algorithms to protect our data/information against hacker attack, the cracking success is a matter of time. Therefore, this project aims at letting students
Requirements:
- Students are required to form a group of 5-6 students as a research team to develop this algorithm. The project will be marked based on students’ analytical capability, research skills, computer programming proficiency, report writing skills.
Work alone to develop the above algorithm using computer programming.Suggested programming languages are c++, Java, php, python.Prepare a 1-min individual video demo of encryption and decryptionPrepare a 5-min individual presentation video with PPT slides explaining the algorithm, show important parts of the program codes, strengths and weaknesses as well as limitations.Total video length [6 mins] = 1-min demo + 5-min presentation
Group task: Simulation and investigation of brute-force password attack [8%]
Work in group develop a program that can generate a random password of length 1-6 chars from ASCII table and then perform brute-force password attack.Suggested OO programming languages are c++, Java, python.The program can tell the time taken to crack a password.Take the time using your written program for different password lengths, e.g. 1 – 6- character long. Repeat 10 times to find the average time taken to crack different lengths of password.Record the time for different password length and plot the graph using log scale (turn the curve not straight line) and interpret the graph.Plot line graphs (with proper axis scaling – Hint: log) using time taken to crack password (y-axis) against the length of password (x-axis)Interpret the line graphs in terms of the relationship between time taken and length of passwordAny observation and interpretation in terms of password length. Do you think bruteforce can attack crack the password easily?Consult and recommend on the length of password against Brute force password attack.Multithreading programs may need to speed up the cracking process and students may use multiple computers to run the program to collect the time result.Prepare ~5-min group video demo of part of password generation and password crackingPrepare ~5-min group presentation video with PPT slides explaining the program, how to generate random passwords and how to perform Brute force attack as well as strengths and weaknesses of the program and limitations. Observation on the password attack, recommendation and conclusion of the password length against attack should be mentioned.Total video length = 10 mins = demo + presentationFor example: 10 mins = 4-min demo + 6-min presentation, 10 mins = 5-min demo + 5-min presentation, … etc.
