Quantum Enabled Key Management

Quantum Enabled Key Management

The Trusted Security Foundation® (TSF®) is an enterprise Key Management Server (KMS) that provides delivery of randomness, management of cryptographic key material, and cryptographic services to clients via several interfaces, including the OASIS Key Management Interoperability Protocol (KMIP), the RSA Data Protection Manager (DPM) protocol, a RESTful API, and a client-side PKCS #11 cryptographic module.

Quantum Random Number Generators

The Challenge

Most security applications use Pseudo-Random Numbers to generate keys. These are generated from a short random seed using deterministic algorithms. They are not truly unpredictable, and have resulted in many security issues.

True Random Number Generators (TRNGs) use random physical processes to generate random numbers. Some are better than others. “True” Random Numbers based on deterministic systems can be predicted if enough is known about the system, or if they can be influenced by actions such as temperature changes.

How Different Types of Random Numbers Impact Security

Our Technology

True Random Numbers generated using quantum physics, called quantum random number generators (QRNG), can be truly random.

Most available quantum random number generators are based on the detection of single photons and have limited throughput. This may result in operational constraints regarding key rotation or number of keys for example.

QuintessenceLabs uses quantum tunneling to deliver truly random numbers at 1Gbit/sec, with flexible form factors and compelling costs, to enable practical, large-scale security and other applications.

Quantum Key Distribution

The Challenge

Key distribution is the process of sharing encryption keys. We typically use public key ciphers, such as RSA, Diffie-Hellman, and ECC, to share symmetric keys that can then encrypt or decrypt data.

This is threatened by weak keys, increased processing power, new attacks, and quantum computers. In just a few years, quantum computers will break these ciphers, preventing us from securely exchanging information. Even now, data encrypted today may well be intercepted and stored for future decryption by quantum computers.

Our Technology

Quantum Key Distribution (CV-QKD) protects data using the laws of physics, making it secure against advanced attacks, in particular quantum computers.

QuintessenceLabs is a leader in the development of CV-QKD. qOptica will all but eliminate the risks of key distribution, since any attempt to intercept the key will leave a detectable trace allowing mitigating action. qOptica delivers high key rates, has a compact form factor, and is well-suited to free-space implementations for practical deployments.

Quantum Enabled Key Management

The Challenge

Cryptographic key management is one of the most complex and high-risk aspects of enterprise security. Organizations must manage growing volumes of keys across diverse environments, algorithms, and vendors—often with fragmented tools and inconsistent policy enforcement. As cryptographic standards evolve and quantum threats emerge, rigid or siloed key management architectures limit crypto agility and increase operational, compliance, and security risk.

Our Technology

The Trusted Security Foundation®️ (TSF®️) KMS addresses this challenge by delivering centralized, policy-driven key management designed for crypto agility and post-quantum readiness. The TSF enables organizations to manage the full cryptographic key lifecycle across heterogeneous environments while supporting rapid algorithm transitions, configurable fallback, and integration with both classical and quantum-resilient technologies. This approach allows enterprises and government agencies to modernize cryptographic infrastructure without disruptive rip-and-replace changes.
