Key Terms

6 terms

quantum-safe encryption technical

"a global leader in PQC migration tooling and quantum-safe encryption, and RAD"

Quantum-safe encryption is a set of cryptographic methods designed to protect digital information from being broken by powerful quantum computers that can defeat many current encryption schemes. For investors, it matters because companies that adopt these future-proof “locks” reduce the risk of data breaches, regulatory penalties and loss of customer trust, and may gain a competitive edge as regulators and partners require stronger data protections.

vpn technical

"offer quantum-safe business services such as site-to-site and site-to-cloud VPNs, as well as Data Center"

A VPN (virtual private network) creates a secure, private “tunnel” through the public internet that hides a device’s location and encrypts the data sent and received, like sealing a letter inside a locked envelope while it travels through the mail. For investors, VPNs matter because they reduce the risk of data breaches, support remote work and regulatory compliance, and represent a recurring-revenue market driver for companies that sell cybersecurity and networking services.

data center interconnect (dci) technical

"site-to-cloud VPNs, as well as Data Center Interconnect (DCI). This announcement follows"

Data center interconnect (DCI) are the high-capacity network links and equipment that tie separate data centers together so they function like one larger facility, moving large volumes of information quickly and reliably. Think of it as wide, fast highways between warehouses that let goods be shifted instantly; for investors it matters because DCI capacity and reliability influence cloud and hosting revenue, operating costs, outage risk and the need for ongoing infrastructure spending.

public-key infrastructure technical

"quantum computing becoming widely available, which will render most public-key infrastructure obsolete."

Public-key infrastructure is the system that creates, distributes and checks pairs of digital codes used to prove identity and secure electronic messages, like a trusted locksmith issuing matched locks and keys for online accounts and documents. For investors, it matters because it underpins secure financial transactions, electronic signatures and data protection across businesses, reducing the risk of fraud, regulatory fines and operational disruptions that can affect a company’s value.

harvest now, decrypt later technical

"current threat in the form of “Harvest Now, Decrypt Later“ (HNDL) attacks, prompting enterprises"

A practice where sensitive digital information is collected and stored in encrypted form today with the expectation that it can be decrypted later when technology or keys become available. Think of it like someone stuffing sealed letters into a safe now because they expect a future key or stronger tools to open them; for investors, it signals long‑term exposure if that stored data becomes readable later, creating legal, regulatory, or reputational risk and potential future costs for affected companies.

post quantum algorithms technical

"By leveraging Arqit’s key generation technology, hybridized with Post Quantum algorithms, and together"

Post quantum algorithms are cryptographic methods designed to remain secure even if powerful quantum computers become available; think of them as new, stronger locks being developed for a future break-in method. For investors, they matter because companies that handle sensitive data, provide cybersecurity products, or depend on secure transactions may face costly upgrades, regulatory requirements, or competitive shifts as markets adopt these new standards.

LONDON, March 02, 2026 (GLOBE NEWSWIRE) -- Arqit (Nasdaq: ARQQ, ARQQW), a global leader in PQC migration tooling and quantum-safe encryption, and RAD, a global leader in networking edge solutions, today announced a collaboration to deliver a joint quantum-safe encryption solution for telcos, enabling them to offer quantum-safe business services such as site-to-site and site-to-cloud VPNs, as well as Data Center Interconnect (DCI). This announcement follows the successful integration of Arqit’s NetworkSecure™ quantum-safe encryption key generation technology with RAD’s high-performance ETX Carrier Edge platform.

This joint solution addresses enterprises’ need for security that is robust enough to thwart the risk presented by quantum computing becoming widely available, which will render most public-key infrastructure obsolete. While this reality is fast approaching, there’s a current threat in the form of “Harvest Now, Decrypt Later“ (HNDL) attacks, prompting enterprises to look at their communications service providers for an immediate solution.

Andy Leaver, CEO at Arqit said:

“The urgent need for institutions globally to fortify their encryption against public key infrastructure weaknesses, HNDL and the fast-approaching quantum threat to long-term data security is beyond dispute. We believe that by collaborating with RAD, telcos will benefit from a crypto-agile and hybrid, post quantum solution.”

Eli Angel, VP Product & Marketing at RAD, said:

“By leveraging Arqit’s key generation technology, hybridized with Post Quantum algorithms, and together with RAD’s unique high speed wireline encryption, we strengthen our quantum security ecosystem, adding another layer of defense to navigate the rapidly evolving landscape of threats and technologies.”
