Hi there ,
I need someone who already worked with the java security libraries to implement this application for me, this project was assigned to undergraduate CS students in my college as a course project on Network Security subject, so i knew it does not worth that much of work , almost all functions are built-in functions , No need to implement any thing from scratch so please do not ask more than the pre-determined budget.
here is the description of the entire project :
As a developer in a company specialized in cyber security solutions development, you were assigned a task to develop a java application for the purpose of data encryption, decryption, secure key exchange, and digital signature.
You are required to develop an application that satisfies the following security standards:
1) The application should make use of a computationally secure and fast encryption/decryption algorithm.
2) The application should support a secure key exchange protocol to share the private key used for encryption and decryption processes.
3) The application should provide a mechanism to ensure the messages integrity and non-repudiation security services through implementing certain security algorithm(s).
Your application should abide to the following specifications:
1. A GUI application where a user can write a message (String) to be encrypted/decrypted, and perform other relevant security functions.
2. The interface should allow the user to generate a symmetric-key, and then encrypt, and decrypt the messages.
3. The user can prepare the symmetric-key to be securely exchanged with other parties through implementing suitable security algorithm.
4. The interface should allow the user to perform certain security function(s) that ensure the integrity of the message and the user cannot deny sending the message.
5. The GUI of your program should be friendly and easy to use.
Scenario example:
• The user can use the GUI to write a string message.
• The user generates the symmetric-key and then encrypt the message.
• The cipher text should be displayed on the screen.
• The user decrypts the message using the same key, and the plaintext should be displayed on the screen to make sure that the crypto algorithm works correctly.
• The user can prepare the symmetric-key to be exchanged securely later.
• Eventually, the user can implement certain security algorithm(s) to ensure the message integrity and non-repudiation.
NOTES :
* you may use any library you need
*I need a full pdf report where you should explain every function implemented as (input/output) and what every function job and what it exactly done.
*AES/DES algorithms could be implemented put i think AES is more suitable to this scenario as it is used in digital signature while DES is not.
* maximum budget for this code is 80-100$ including (GUI + FULL REPORT DESCRIBING ALL FUNCTIONS)
