Ciphertext
Definition
Ciphertext is data that has been transformed through encryption into an unreadable format. Only parties possessing the correct decryption key can recover the original plaintext from ciphertext. Well-designed ciphertext reveals nothing about the underlying message to unauthorized observers.
Technical Explanation
Modern encryption algorithms produce ciphertext indistinguishable from random data (semantic security). Each encryption with the same key produces different ciphertext due to random initialization vectors, preventing pattern analysis. Ciphertext length typically relates to plaintext length but reveals no content information.
The threat of quantum computers motivates post-quantum encryption. Ciphertext encrypted with classical algorithms like RSA could be stored and later decrypted by quantum computers. Ciphertext protected by quantum-resistant algorithms like Kyber remains secure indefinitely, even against future quantum attacks.
Ciphertext Sizes: Classical vs Post-Quantum
| Algorithm | Type | Ciphertext Size | Quantum Safe |
|---|---|---|---|
| RSA-2048 | Classical PKE | 256 bytes | No |
| ECDH (P-256) | Classical KE | 65 bytes | No |
| AES-256-GCM | Symmetric | plaintext + 28 bytes | Yes |
| Kyber-768 | Post-Quantum KEM | 1,088 bytes | Yes |
While post-quantum ciphertexts are larger, the difference is negligible on modern networks. A single Kyber encapsulation adds roughly 1 KBโinvisible in an era of gigabit connections.
SynX Relevance
All sensitive SynX communications produce quantum-resistant ciphertext using Kyber-768 encapsulation and AES-256-GCM symmetric encryption. Whether it's wallet-to-daemon messages, encrypted transaction payloads, or P2P marketplace communications, adversaries capturing this ciphertext cannot decrypt itโnot today with classical computers, and not tomorrow with quantum computers.
This directly defeats the harvest now, decrypt later strategy where nation-state adversaries collect encrypted traffic for future quantum decryption. SynX ciphertext captured today will remain opaque forever.
Frequently Asked Questions
- Can anyone decrypt my SynX ciphertext?
