Encryption & Data Handling
Security is the foundation of Secure Lattice, not just in the data it protects, but in how it proves that protection. Every layer of the network, from endpoint telemetry to on-chain proofs.
Data Flow Architecture
All data entering the Secure Lattice ecosystem is handled through a zero-trust pipeline:
Local Encryption – The Lattice Agent encrypts all collected telemetry (process hashes, event logs, system metadata) using device-level symmetric keys (AES-256-GCM).
Metadata Hashing – Before transmission, the telemetry is stripped of any sensitive payloads and hashed (SHA-3-512).
Ephemeral Tunnels – Data is transferred using TLS 1.3 with Perfect Forward Secrecy (PFS), and ephemeral session keys are rotated every 15 minutes or per 500 MB of data.
On-Chain Anchoring – Only the hash proofs of security events are committed to the BNB blockchain. The original data never leaves the secured environment.
This ensures that even if the blockchain were fully public, no sensitive information could be reconstructed.
Key Management
Device Keys are generated via Curve25519 elliptic curve cryptography during agent installation.
Session Keys are derived from Diffie-Hellman key exchange and rotated at configurable intervals.
Validator Keys use Hardware Security Modules (HSMs) for signature isolation.
Recovery and Rotation follow NIST SP 800-57 guidelines, ensuring forward secrecy and revocation on device decommission.
Example (Pseudo-Code)
from cryptography.hazmat.primitives.asymmetric import x25519
from cryptography.hazmat.primitives.kdf.hkdf import HKDF
from cryptography.hazmat.primitives import hashes
# Device key exchange
private_key = x25519.X25519PrivateKey.generate()
public_key = private_key.public_key()
shared_secret = private_key.exchange(peer_public_key)
session_key = HKDF(
algorithm=hashes.SHA256(),
length=32,
salt=None,
info=b"secure-lattice-session"
).derive(shared_secret)Each telemetry payload is encrypted with this session_key, guaranteeing compartmentalized exposure.
