Encryption and Security

DÆTA implements cutting-edge encryption and security protocols to protect the privacy and integrity of all stored data.

DÆTA employs state-of-the-art encryption and security measures to ensure the privacy and integrity of stored data.

Encryption Layers

1. Client-Side Encryption

AES-256-GCM for file encryption

Unique key generated for each file

2. Transport Layer Security

TLS 1.3 for all network communications

3. Shard-Level Encryption

Additional encryption applied to individual file shards

Key Management

graph TD
    A[Master Key] -->|Derives| B(File Encryption Key)
    A -->|Encrypts| C(Metadata Encryption Key)
    B -->|Encrypts| D[File Content]
    C -->|Encrypts| E[File Metadata]
    A -->|Securely Stored| F{User's Wallet}

Security Measures

Zero-Knowledge Proofs

Verify data integrity without revealing content.

Multi-Factor Authentication

Secure account access.

Regular Security Audits

Identify and address vulnerabilities.

Bug Bounty Program

Incentivize discovery of security issues.

Trustless Architecture

No single point of trust in the system.

Encryption Process

Example

from cryptography.hazmat.primitives.ciphers.aead import AESGCM
import os

def encrypt_file(file_path, encryption_key):
    # Generate a random 96-bit IV
    iv = os.urandom(12)
    
    # Create an AES-GCM cipher instance
    aesgcm = AESGCM(encryption_key)
    
    with open(file_path, 'rb') as file:
        plaintext = file.read()
    
    # Encrypt the file content
    ciphertext = aesgcm.encrypt(iv, plaintext, None)
    
    # Prepend the IV to the ciphertext
    encrypted_data = iv + ciphertext
    
    return encrypted_data

# Usage
file_path = '/path/to/sensitive_document.pdf'
encryption_key = AESGCM.generate_key(bit_length=256)
encrypted_file = encrypt_file(file_path, encryption_key)

# The encrypted_file can now be safely split into shards and distributed

By implementing these core concepts, DÆTA provides a robust, secure and efficient decentralized storage solution that addresses the limitations of traditional centralized systems while leveraging the power of distributed networks.
