Distributed Symmetric Key Exchange
Delivering the industry’s first symmetric key distribution technology that achieves future-proofed security at scale, without asymmetric encryption.
Trusted technology for defense-in-depth
Organizations rely on key distribution to exchange and protect highly sensitive data. But legacy key management processes can be error-prone, expensive to manage – and breakable. Distributed Symmetric Key Exchange (DSKE) is a modern key distribution technology. It fully automates the creation and distribution of symmetric keys, without relying on computational complexity or asymmetric encryption. DSKE is the industry’s first scalable symmetric key technology, combining the scalability of PKI, the security of quantum key distribution (QKD) and the simplicity of pre-shared keys.
Automate the creation and distribution of symmetric keys
DSKE provides your organization with information-theoretically secure, quantum-safe cryptographic keys to protect data across network communications today, and in the future.
State-of-the-art communication technology that is rooted in proven principles
Protect against computational attack
The security of DSKE is independent of the classical or quantum computational power of potential adversaries and comes with proof of information-theoretical security.
Scale with ease
On-board new clients at any time, without affecting existing clients or their ability to communicate.
Establish decentralized trust
DSKE relies on a key delivery process that is based on a decentralized set of security hubs, eliminating the need for trusted service providers.
Ensure Randomness
DSKE uses quantum random number generation for keys used in both encryption and authentication.
Achieve robust security
DSKE helps your organization to achieve communication robustness and security that can operate over the most hostile networks.
Automate symmetric key generation and distribution
Current pre-shared key solutions are labor-intensive and difficult to scale. DSKE eliminates errors, saves time and reduces symmetric key management costs.
Eliminate the single point of failure
Ensure fault tolerance and reliability through a decentralized solution where there is no single point of failure, or single point of trust.
Support computational efficiency
DSKE is suitable for even the most resource-constrained devices like smartphones, ICS and SCADA systems and IoT devices.
Distributed Symmetric Key Exchange (DSKE) delivers symmetric key distribution with perfect secrecy
Quantum Bridge delivers unbreakable network and endpoint security solutions to organizations that require information-theoretic security to encrypt and exchange highly sensitive and classified information.
Globally scalable
DSKE is the first globally scalable symmetric key distribution technology that enables the distribution of quantum-endowed keys at scale.
Seamless Integration
DSKE’s key distribution seamlessly integrates with your organization’s existing operations, infrastructure and standard symmetric encryption models like the Advanced Encryption Standard (AES) and information-theoretic secure encryption like one-time pad (Vernam cipher).
Unbreakable
DSKE doesn’t rely on PKI or asymmetric key encryption. It is an unbreakable key distribution solution that can be delivered as a network appliance or endpoint-based solution, depending on your organization’s use cases and security requirements.
Vendor-angostic
DSKE is vendor-agnostic and integrates with any network appliance or endpoint device. It is also layer-agnostic, and can be integrated into any layer of the network infrastructure. DSKE doesn’t rely on PKI or asymmetric key encryption.
How it works
DSKE clients receive secret random data from multiple security hubs. The DSKE protocol allows clients to generate symmetric keys protected by secret sharing. The security hubs cannot discover client’s keys unless a majority collude. Read more about DSKE from our white paper.
