SPHERE Project
Welcome to the SPHERE (Secure Peer-to-Peer Hosted Encryption Record Exchange) repository!
SPHERE is a highly secure, decentralized framework designed for peer-to-peer communication, encrypted data exchange, and decentralized identity management. It offers robust privacy, data integrity, and cryptographic security while maintaining scalability and efficiency for various applications.
Active Development
This project is a work in progress, with ongoing improvements to enhance security, scalability, and decentralized efficiency.
Key Features
Secure Contact List Management
- Unified, decentralized contact list across all SPHERE applications.
- Full user control over contacts, including key rotation and access permissions.
- Peer-to-peer (P2P) architecture eliminates reliance on centralized servers.
End-to-End Encryption
- Uses AES256, RSA2048, and ECDsa algorithms for top-tier security.
- Dynamic key generation for each communication session.
- Private keys stored in secure local containers (CNG) without export unless explicitly allowed.
Decentralized Networking
- Built on a Distributed Hash Table (DHT) for efficient peer discovery and data exchange.
- Uses a Kademlia-based routing table to optimize node connectivity.
- Integrated Gossip Protocols for propagating data across the network.
Modular and Scalable Design
- Plug-and-play modules for encryption, authentication, routing, and token management.
- Scales efficiently even in resource-constrained environments (e.g., mobile clients).
Digital Signature Verification
- Verifies message authenticity and integrity using ECDsa signatures.
- Prevents tampering and validates the origin of messages.
Token-Based Proof of Work
- Implements a token system for peer validation and incentivized interactions.
- Tokens are issued for completed actions (e.g., message relays) and spent on data requests.
Reputation Management
- Dynamic trust scores based on peer behavior and network contributions.
- Penalizes malicious actions and rewards reliable participation.
High Scalability and Performance
- Adaptive sharding splits the DHT into manageable chunks.
- Dynamic load balancing ensures efficient resource use across nodes.
Technical Breakdown
Core Components
Encryption Module (Encryption.cs)
- Implements symmetric and asymmetric encryption.
- Hybrid key management for secure communications.
- Encrypted local symmetric keys (LSK) for contact data confidentiality.
Packet Management (Packet.cs)
- Defines and serializes packets for node-to-node communication.
- Includes validation for packet types, TTL, and cryptographic signatures.
Service Account Management (ServiceAccountManager.cs)
- Manages encryption keys bound to service accounts for added security.
- Uses CNG containers that prevent unauthorized key access.
Distributed Hash Table (DHT) (DHT.cs)
- Handles decentralized storage and retrieval of contact, reputation, and transaction blocks.
- Uses a Kademlia-based routing algorithm for efficient node lookups.
Networking Layer (NetworkManager.cs, Client.cs)
- Handles all network communication between nodes.
- Integrates STUN/TURN for NAT traversal and port discovery.
Reputation System (Reputation.cs)
- Evaluates node behavior based on network participation.
- Adjusts reputation scores dynamically.
Security Features
- End-to-End Encryption: Each message is securely encrypted from sender to recipient.
- Secure Key Exchange: Uses Diffie-Hellman key exchange for secure session initiation.
- Digital Signature Verification: Validates message authenticity and integrity.
- Anti-Replay Protection: Prevents replay attacks using timestamped messages and nonces.
