Encryption in Transit

Definition

Encryption in transit protects data as it moves between systems over networks. It prevents eavesdropping, man-in-the-middle attacks, and data interception. TLS/SSL for web traffic and encrypted peer-to-peer protocols are common implementations.

Technical Explanation

Transport encryption establishes secure channels between endpoints. Key exchange (typically Diffie-Hellman variants) creates shared secrets. Symmetric encryption (AES) protects bulk data. Message authentication codes verify integrity. Forward secrecy ensures past communications stay secure even if keys are later compromised.

The quantum threat applies here: harvest-now-decrypt-later attacks record encrypted traffic for future quantum decryption. Post-quantum key exchange (Kyber) protects against this by making recorded traffic quantum-safe from the start.

SynX Relevance

SynX node communication uses encrypted channels protecting peer-to-peer traffic. As post-quantum TLS becomes standard, SynX infrastructure will adopt quantum-resistant transport encryption—ensuring network traffic remains private against future threats.

Frequently Asked Questions

Is blockchain traffic encrypted?: Node-to-node communication uses encryption; transactions themselves are cryptographically secured.
Can my ISP see my SynX transactions?: They see encrypted traffic to the network but not transaction contents or amounts.
What about harvest-now-decrypt-later?: SynX transactions are quantum-resistant—even if recorded, they resist future quantum attacks.
