We have been responsible for a series of world firsts in quantum technology and performance and we continue to push the boundaries of quantum technology.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Background<\/strong><\/p>\n\n\n\n<p>The public key encryption techniques used today to secure much of our data online are no match for quantum computers. The dawn of the quantum age requires a new kind of security. Quantum Key Distribution (QKD) involves the transmission of quantum-safe cryptographic keys using a technique which secures online transmissions, even against quantum computers.<\/p>\n\n\n\n<p>\u201cUnlike other existing security solutions, quantum cryptography is secure from all future advances in mathematics and computing \u2013 even from the number-crunching abilities of a quantum computer.\u201d &#8211; Dr Andrew Shields, Head of Toshiba Quantum Technology Division<\/p>\n\n\n\n<p>Organisations will have to carefully manage the deployment of these quantum-secure keys throughout their QKD networks.<\/p>\n\n\n\n<p>Toshiba\u2019s Q-KMS makes the process simple.<\/p>\n\n\n\n<p><strong>What is a quantum key management system?<\/strong><\/p>\n\n\n\n<p>A Q-KMS is a cryptographic key management system for the quantum age. It operates in tandem with the QKD network, generating and distributing quantum secure keys between trusted nodes \u2013 similar to TCP\/IP, but for quantum transmissions.&nbsp;<\/p>\n\n\n\n<p>The Q-KMS distributes and stores keys as required, allowing the operator to have high key refresh rates if they so wish.<\/p>\n\n\n\n<p><strong>How does Toshiba\u2019s Q-KMS work?<\/strong><\/p>\n\n\n\n<p>Toshiba abstracts the Q-KMS from the physical layer, meaning we can provide a logical key delivery overlay across a network infrastructure.<\/p>\n\n\n\n<p>While previous QKD systems have only operated point to point, the advent of Q-KMS means that QKD-secured mesh networking is now available. In a QKD network with a mesh architecture (as in the diagram below), the Toshiba Q-KMS can route around potential fibre breaks, increasing system resilience<\/p>\n\n\n\n<p><strong>Do you need to use a <a>Q-KMS<\/a><\/strong><a href=\"#_msocom_1\">[WF1]<\/a>&nbsp;<strong> with quantum key distribution systems?<\/strong><\/p>\n\n\n\n<p>Yes, if you\u2019re using a QKD system in your network, you will need a quantum key management system to route and deliver the quantum-secure cryptographic keys. That\u2019s why Toshiba provide a Q-KMS in addition to our QKD systems. Toshiba\u2019s Q-KMS is compatible with quantum key distribution systems from other QKD vendors, or other applications (such as encryptors) that comply with the ETSI GS QKD 014 standard.<\/p>\n\n\n\n<p><strong>Is a quantum key management system the same as a key management system?<\/strong><\/p>\n\n\n\n<p>A Q-KMS is the quantum-secure equivalent of a standard cryptographic key management system (KMS), but designed specifically to store, distribute, and manage the keys required within a quantum-secure network.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><a id=\"_msocom_1\"><\/a><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><a id=\"_msocom_3\"><\/a><\/p>\n\n\n","protected":false},"excerpt":{"rendered":"<p>The quantum age demands quantum-secure networking.
