Methodology / Approach

Mechanism of Proposed Project BlockDef

We designed a system where we use IPFS to achieve decentralization and secure peer-to-peer communication[17] between Military Chief And Government Office. Encrypting files and our packets to ensure more safety is also used in python framework, for compatibility. The web development is done with the help of Django[18].

A quick walkthrough of the project:

• The military office from the datasheet in its local storage send instructions to  to the designated military chief to send important files
• As the military office send the instructions to the military chief, they accept it and download the instruction pdf to their local machine.
• After getting instructions, the military chief set the important files and upload it to the server in pdf format to send the file.
• Now this pdf file when prepared and encrypted with symmetric key, is sent to the distributed file system which is IPFS
• IPFS divides the file into various chunks. These chunks are stored on a decentralized server and each chunk’s hash is generated. The hashes are combined to give one hash to retrieve the file
• Further, this hash along with other particulars is sent to be stored in block chain ledger
• Submitted papers start showing on Military Office portal without any details of file and chief. So military office finalizes the file and sends to Government Office.
• The government office receives these details. Government office gets details of file retrieval from block chain ledger.
• After getting the details automatic request to  retrive file from IPFS is sent and then government office gets the original paper.

Uses of Zero-Proof Authentication in BlockDef

In BlockDef Zero-knowledge proof methods are utilized to bolster the privacy and security of user credentials. The User model incorporates a zero-knowledge proof field, which contains a cryptographic proof validating the user’s identity without disclosing any sensitive information. This ensures that even in the event of a system breach, user data remains safeguarded. By the application of  zero proof authentication[19] , the proposed system eradicates vulnerabilities associated with single points of failure and guarantees data immutability. This ensures that unauthorized alterations to user data become highly impractical, offering robust protection against common attack methods such as data tampering[20] and replay attacks[21].

Unit Testing:

Unit Testing is a software testing approach that focuses on testing individual components or units of software to ensure they perform according to their design. It involves testing various modules separately to validate their functionality. In our project, we had three modules, each with its own testing process.

• For the Blockchain Module, we conducted tests specifically on the blockchain system to ensure that all provided functionalities were functioning correctly. Initially, we implemented Hyperledger Fabric for the blockchain network and tested transactions within the Blockchain Ledger. The outcome of the testing was successful.
• In the Web + Data Storage Module, we performed tests to verify the proper functioning of front-end functionalities on the website and to ensure that all data involved in the system was stored correctly in either the local or online distributed database. The testing results indicated successful implementation.
• The Security Module underwent testing to assess the effectiveness of security enhancement techniques, such as symmetric and asymmetric encryption, and to identify any potential vulnerabilities in these methods. The testing concluded with successful results.

Overall, the unit testing process for each module confirmed the successful implementation of the functionalities and security measures within the system.

System Testing:

System Testing is a software testing method that evaluates the overall compliance of a fully integrated system with its defined requirements. Following the integration testing phase, we explored alternative approaches to integrate the Blockchain module with the (web+security) module and discovered that Hyperledger Composer could facilitate seamless interaction between the web and Blockchain server. As a result, all system functionalities are functioning in accordance with the specified requirements. The outcome of the system testing was successful.
