Quantum Optics Jena's ELVIS Enterprise systems are based on entangled photon, where security depends only on the receivers. With this source-independent quantum key distribution (QKD) protocol, an attacker gains nothing by compromising the source. Built on the fundamental laws of physics from the ground up: the system generates entangled photons in a superposition state, distributes them over fiber-optic infrastructure with no restrictive assumptions on the quantum channel, and completes the process with the measurement of the individual photons.
When it comes to security, choose true quantum.
ELVIS Enterprise is highly reliable for continuous operation in data centers, backed by responsive service, with redundant configurations for uninterrupted operation. It is cost efficient, integrate easily with existing infrastructure, and offer comprehensive configuration and monitoring tools for the operator.
From two-node links to large multi-node networks over long distances, our systems support all kinds of infrastructure – and grow with your requirements.
We deliver on our promise: Secure. Reliable. Scalable.
How it works
The ELVIS Enterprise QKD system consists of three devices to supply secure keys to two communication endpoints – or network nodes.
The ELVIS Enterprise system requires just a single standard 1550 nm telecom fiber from the quantum source to each receiver. It also uses a standard, non-confidential, 8 Mbps (or lower) TCP/IP connection between the two receivers to run the quantum protocol.
The two ELVIS Quantum Receivers generate secret keys that they supply to their node's data encryptor. The encryptors are not part of the ELVIS Enterprise system, they are chosen by the customer. The ELVIS Quantum Receivers support standard key interface protocols, making them compatible with market leading key management systems, hardware security modules, key combiners, encryptors/decryptors and even end-to-end-encrypting software applications.
The properties of quantum physics:
- Both nodes receive highly random and identical symmetric keys.
- Any attempt of an attacker to manipulate the Quantum Source or the transmitted photons, or to eavesdrop on the photons, will be immediately detected. This detection will be recorded and reported, and the suspect photons will not be used to generate keys.
- Unlike most other technologies, including post-quantum cryptography (PQC) as well as non-entanglement-based QKD, no quantum random number generator (QRNG) is required. The ELVIS Enterprise system is a distributed QRNG, delivering identical random keys to both nodes.
