Perform collision resistance analysis on the otp generation

Assignment Help Computer Network Security
Reference no: EM131715167

Overview

In this assignment you will develop an event based onetime password (OTP) system. The system consists of the following components:
1. A soft OTP token UI which consists of a push button and a display control. Clicking on the button will generate and display the onetime password.
2. A test UI which will prompt the user to provide the OTP, show access granted message only if the right OTP is entered.
You will need to do the following:

1. Develop, build and test the UI components.
2. Implement a synchronization mechanism if the two apps get out of sync.
3. Perform Collision Resistance analysis on the OTP generation algorithm. Use the following algorithm to generate the OTPs:
Feedback One-Time Password Algorithm (FOTP)

Hash Feedback One-Time Password Algorithm described in the following chart. Secret key is used as the initialization vector. The first OTP is generated by hashing this vector. The second OTP is generated by hashing the hash generated by the first the 1st OTP, and so on. The OTP is calculated by truncating the hash into a six digit value.

You can set Key = 989670FF00FF00012.

Collision Resistance

This property describes the probability of generating the same OTP over a period of time. A good OTP generation algorithm should demonstrate strong collision resistance. Two metrics are calculated in N number of OTPs:
CR1: the number of similar OTPs in N.

CR2: the number of similar two consecutive OTPs in N (Optional +5%).

You will need to submit the following:

1. Complete source code and screen captures of the running program.
2. A study of the collision property. Generate 1,000,000 OTPs using your application. Show a graph describing how the collision properties evolve as the number of OTPs increases.

Verified Expert

In this assignment we have studied cryptography. Here we have also studied java programming and use java code to generate OTP’S.In this task we studied feedback one time password generation algorithm. In this we have also studied hash algorithm i.e. SHA256 for otp generation.

I want the source code. A study of the collision property. Generate 1,000,000 OTPs using your application. Show a graph describing how the collision properties evolve as the number of OTPs increases. 1.Complete source code and screen captures of the running program. can u give me some clarification about what has to submit for this assignment?

Yup,i got it..thank you. There are 7 source codes,so can I place those headings & source code under them?& I want to know how to run in netbeans Only extract solution folder open netbeans go to file menu choose open project option and browse project folder.you project will be open in netbean and run it by clicking on green triangle button There are 4source codes,base64,collisioin generator,fbotp generator,securtyaboutbox.now ihave to copy all this & can I place in solution file as a source code(combining these 4files/)? I have done the solution of this assignment in netbeans project, Please download netbeans and install it open it you will get output and I have provided collision properties in word file and Also, i have provided source code in zip file and running screenshot in the word file. send me whole source code file in text format.i have to submit everything in single file.In a single file,i had to include source code,10k opts & solution file(graph) Thank you.
