How It Works
Encryption you can actually trust.
TMS uses a layered security model combining the world's strongest encryption algorithms.
AES-256-GCM Message Encryption
Each message encrypted with a unique 256-bit key using Galois/Counter Mode.
X25519 Key Exchange
Elliptic Curve Diffie-Hellman — shared secret derived without transmission.
Forward Secrecy via Signal Protocol
New keys for every session. Past messages remain unreadable even if a key is compromised.

FAQ
Common questions.
Can TVB Network read my messages?
Absolutely not. TMS uses zero-knowledge architecture — your encryption keys are generated on your device and never transmitted to our servers. It is technically impossible for TVB Network to decrypt your messages.
What encryption does TMS use?
AES-256-GCM for message encryption, X25519 for key exchange, SHA-3-512 for integrity, and the Signal Protocol's Double Ratchet algorithm for forward secrecy.
Is TMS POPIA and GDPR compliant?
Yes. TMS is built with POPIA and GDPR compliance at its core. Our zero-knowledge model means we don't store personal data we can't access.
Can I deploy TMS on my own servers?
Yes, on-premise and private cloud deployment is available on our Enterprise plan with complete infrastructure control.

Security Architecture
Built for the paranoid. Trusted by the rest.
TMS implements multiple overlapping layers of cryptographic protection. Here is every layer, explained plainly.
AES-256-GCM Encryption
256-bit keys with Galois/Counter Mode. Brute-forcing a 256-bit key would take longer than the age of the universe.
X25519 Elliptic Curve Key Exchange
State-of-the-art Diffie-Hellman on Curve25519. Keys are derived locally and never leave your device.
Signal Protocol — Double Ratchet
Forward secrecy and break-in recovery. New encryption keys for every message — mathematically provable.
SHA-3-512 Integrity Hashing
Every message integrity-verified. Any tampering — even a single bit — is immediately detected and rejected.
Zero-Knowledge Architecture
Servers store only encrypted blobs. No message metadata logged. We cannot produce your messages to any legal demand.
Secure Enclave & Biometric Auth
Encryption keys stored in hardware Secure Enclave. Physical device access does not expose keys without biometrics.
Compliance Standards
TMS meets the world's strictest privacy and security standards.
