Abstract :

The Rapid Growth Of Distributed Applications Has Significantly Increased The Need For Secure And Efficient Data Exchange, Exposing The Limitations Of Traditional Centralized Systems. Conventional File-sharing Architectures Rely On A Central Server For Authentication And Storage, Which Creates Critical Vulnerabilities Such As Single-point Failure, Identity Exposure, And Limited Scalability. These Centralized Models Also Introduce Performance Bottlenecks And Security Risks In Distributed Environments. Existing File-sharing Solutions Often Fail To Provide Reliable Identity Verification Across Distributed Nodes, Making Them Vulnerable To Impersonation, Interception, And Unauthorized Data Access. Many Traditional Systems Depend On Static Credentials And Computationally Intensive Cryptographic Algorithms, Which Increase Processing Overhead And Reduce Overall System Performance. Furthermore, These Approaches Rely Heavily On Centralized Identity Servers And Insecure Key Exchange Methods And Suffer From High Latency, Making Secure Collaboration Between Multiple Nodes Difficult. To Address These Limitations, This Work Proposes A Secure Decentralized Filesharing System Implemented Using A Djangobased Web Platform Integrated With A Peer-toPeer (P2P) Networking Architecture And Elliptic Curve Cryptography (ECC). In The Proposed Model, If A Requested File Is Not Available Locally, The Peer Initiates Secure ECC-based Authentication With Another Peer And Retrieves The File Directly. This Mechanism Ensures Confidentiality, Integrity, And Anonymity During File Transmission Without Requiring A Centralized Authority. The Django Framework Efficiently Manages User Interactions, Authentication, Database Validation, File-handling Operations, And System Performance Visualization. The Proposed System Offers Strong Security With Low Computational Overhead And Full Decentralization. By Utilizing ECC, Which Provides High Cryptographic Strength With Smaller Key Sizes, The System Achieves Faster And More Efficient Performance Compared To Traditional RSA Or Diffie–Hellman-based Solutions. Keywords: Decentralized File Sharing, Peerto-Peer (P2P) Networking, Elliptic Curve Cryptography (ECC), Django Web Framework, Secure Data Transmission.
