Benefits of Symmetric Encryption
A Faster, Stronger, and More Scalable Foundation for Data-Centric Security
Cord3 Unity exclusively uses symmetric cryptography to protect data. Using symmetric cryptography for DCS encryption provides various benefits and solves problems that have historically hindered the development and adoption of DCS solutions. Specifically, Cord3’s approach separates the policy decision and encryption operations, so policy changes can be made anytime and data does not need to be re-encrypted. Traditional approaches to DCS, which leverage asymmetric cryptography, protect data for a specific community. With Cord3’s approach, protection is focused on the data itself.
Asymmetric encryption approaches, such as PKI, use algorithms that are inherently weaker than symmetric algorithms in the face of emerging quantum cryptanalysis threats. Asymmetric cryptography is also slower than symmetric key cryptography, resulting in bottlenecks over time.
Why Symmetric Encryption Matters
Symmetric cryptography uses a shared secret key to encrypt and decrypt data. When implemented at scale using Cord3’s KeyFrame™ model, it delivers major advantages for real-time, distributed security environments.
Key Benefits
High Performance at Scale. Symmetric algorithms are significantly faster than asymmetric algorithms, making them ideal for large data volumes and real-time operations.
Stronger Quantum Resistance. Symmetric encryption is inherently more resilient to emerging quantum cryptanalysis threats than widely used asymmetric algorithms.
Efficient for Element-Level Protection. Symmetric cryptography enables encryption at the data element level without introducing unacceptable latency.
No Re-Encryption When Policies Change. Cord3 separates policy decisions from encryption. Access rules can change instantly without touching the encrypted data.
Lower Computational Overhead. Reduced processing demand supports deployment across constrained, distributed, and mission-edge environments.
Cord3’s Approach vs. Traditional PKI Models
| Capability | Cord3 Symmetric Model | Traditional PKI / Asymmetric Encryption |
|---|
| Performance | Optimized for high-speed, large-scale data protection | Slower due to complex mathematical operations |
| Scalability | Easily scales to millions of protected data elements | Key management becomes complex at scale |
| Policy Flexibility | Policies can change without re-encrypting data | Policy changes often require re-encryption |
| Quantum Readiness | More resistant to quantum attacks (with strong key lengths) | Many PKI algorithms are vulnerable to future quantum threats |
| Operational Overhead | Zero key management burden with KeyFrame™ | Certificates, revocation lists, and key lifecycle management required |
| Protection Focus | Protection bound directly to the data | Often tied to users, devices, or sessions |
| Mission Agility | Supports dynamic coalition and cross-domain access | Rigid trust relationships slow coalition integration |
The Problem with PKI-Dependent Data Security
PKI was designed primarily for identity verification and session security, not persistent, element-level data protection.
When used for Data-Centric Security, PKI-based systems often:
- Lock data to specific users or groups
- Require complex certificate and key lifecycle management
- Struggle in disconnected or segmented environments
- Create performance bottlenecks at scale
- Face long-term uncertainty due to quantum vulnerabilities
These limitations make PKI ill-suited for high-volume, multinational, multi-domain defence operations.
Cord3 KeyFrame™: Making Symmetric Security Scalable
Cord3’s KeyFrame™ symmetric key model overcomes traditional symmetric key distribution challenges.
KeyFrame:
- Generates as many unique keys as needed
- Harvests keys on demand from a protected source
- Eliminates manual key distribution
- Enables secure synchronization across locations
- Uses tokens that travel with data but never reveal keys
This delivers the performance advantages of symmetric encryption without the historical management burden.
Built for the Future of Defence Data Security
Cord3’s symmetric-first design supports:
- Element-level data protection
- Real-time coalition interoperability
- High-speed operational environments
- Policy-driven Zero Trust enforcement
- Long-term resilience against emerging cryptographic threats
Faster. Stronger. Simpler.
Cord3 Unity proves that Data-Centric Security does not need to be complex to be powerful. By choosing a symmetric cryptographic foundation and pairing it with the KeyFrame model, Cord3 delivers a modern, scalable alternative to legacy PKI-based approaches.
