Provably Secure Encryption
Hackers steal data constantly, so protecting it is an ongoing challenge. Today’s information encryption technology has been compromised and will be obsolete in just a few years. Quantum Key Distribution (QKD) technology can be proven by the laws of physics to help secure the sensitive data we deliver—today and into the future.
The Challenge
Developments in communication technology have created a world of faster and more convenient exchange of information. Data that is essential to business operations need to be accessible across departments and transferrable to other companies that work within a network. These might include user reports such as financials, medical records and corporate data, such as patent information, trade secrets, and pharmaceutical formulas. However, all of this proprietary information that passes through our current communication channels are susceptible to unauthorized access. As the world develops faster computer technology and more powerful quantum computers, the current data protection methods will no longer be effective.
The Solution: QKD
Realizing this, Battelle has partnered with ID Quantique and aggressively developed a working network of computer facilities that safely pass information keys to unlock their own encrypted data. This technology, known as Quantum Key Distribution is the only key transfer method that is provably secure from an information-theoretic standpoint to help secure the sensitive data we deliver.
Battelle’s Quantum Key Distribution Network
Battelle has partnered with ID Quantique in Geneva to solve the problems of QKD penetration in the US market. In 2013, Battelle installed the first commercial QKD system in the US, connecting Battelle’s headquarters in Columbus, Ohio to its production facility in Dublin, Ohio. The QKD hardware used in this link is the Cerberis model from ID Quantique. Combined with ID Quantique’s Centauris encryptor, this provides a 1Gbps link with Layer2 encryption. The link between facilities requires dedicated dark (unlit) fiber. The partnership with the City of Dublin and dubLINK provides access to dark fibers that are located at the production facility in Dublin and continues in a ring around the metropolitan area of Columbus. Battelle built its own fiber link to connect the Columbus headquarters to this ring providing the continuous dark fiber link needed for the QKD network to function.
Next Generation QKD Network
QKD’s greatest limitation in the US is the maximum distance it can travel along a fiber. Battelle is working with ID Quantique to create a new quantum device called a QKD Trusted Node™. The QKD Trusted Node will allow a quantum network to expand the distance of QKD and to allow multiple destinations while retaining the secure nature of QKD. Battelle is planning a prototype which will be used to start connecting other Battelle offices in the metro area. The connection of three sites will create the Battelle Quantum Network (BQN) that will serve future Trusted Node sites in Columbus, creating a ring in Columbus that Battelle and others can connect to for secure keys.
Using the Trusted Node, Battelle plans to further expand the BQN out from the Columbus, Ohio metro area and connect to their offices near Washington, DC. The total distance for this network would be over 700km/420mi making it the largest known QKD network in the world.
