# Security
|
||
|
||
_This document is under construction. We are actively refining its content, so please check back for updates._
|
||
|
||
## Overview
|
||
|
||
Security is a foundational pillar of DSFX. Our goal is to protect user data and network communications against potential adversaries by integrating advanced cryptographic algorithms, rigorous protocol designs, and best practices in secure coding. In DSFX, every interaction—from file exchanges to authentication handshakes—is carefully engineered to minimize risks and uphold the integrity and confidentiality of the system.
|
||
|
||
## Key Principles
|
||
|
||
- **Robust Cryptography:**
|
||
DSFX leverages industry-standard symmetric and asymmetric encryption techniques. Files and messages are encrypted using AES-GCM for authenticated encryption, ensuring data remains confidential and tamper-proof during storage and transit.
|
||
|
||
- **Mutual Authentication:**
|
||
Using a combination of ephemeral Diffie–Hellman key exchange and digital signatures based on ED25519, DSFX executes secure handshakes where both parties validate each other’s identity. This mutual authentication strategy prevents man-in-the-middle attacks and ensures that only legitimate nodes can participate in the network.
|
||
|
||
- **Integrity and Non-Repudiation:**
|
||
By signing every exchange with strong cryptographic signatures, DSFX not only protects the integrity of data but also guarantees non-repudiation. Any alteration or tampering with the data during transit is immediately detectable via failed signature verifications.
|
||
|
||
- **Defense-in-Depth:**
|
||
Security in DSFX is implemented in multiple layers—from low-level cryptographic routines and length-prefixed framing to high-level decentralized key management. This layered approach ensures that even if one mechanism fails, other safeguards remain to protect the system.
|
||
|
||
- **Adherence to Secure Coding Practices:**
|
||
Inspired by our internal axioms, our implementation enforces strict safety and correctness guidelines. We use assertions liberally, integrate explicit error handling, and maintain rigorous controls over resource usage to fend off potential vulnerabilities such as buffer overflows or memory corruptions.
|
||
|
||
## Future Directions
|
||
|
||
In upcoming revisions, we plan to delve deeper into:
|
||
|
||
- Detailed technical explanations of the cryptographic routines used (e.g., AES-GCM, ED25519, ECDH key exchanges).
|
||
- An in-depth look at our secure handshake protocol, discussing its design, potential threats, and mitigation strategies.
|
||
- Comparisons with other security models to highlight the advantages provided by DSFX’s layered defense mechanism.
|
||
- Practical considerations and best practices for maintaining a secure environment when deploying DSFX.
|

_This section is actively evolving as we continue to assess security challenges and integrate improvements in our design and implementation._
