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)

    B -->|Encrypts| D[File Content]
    C -->|Encrypts| E[File Metadata]
    A -->|Securely Stored| F{User's Wallet}

Security Measures

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.
