Founded in Paris in 2019, VeriQloud is expanding its post-quantum data security solutions to North America as the threat to current encryption methods rapidly intensifies. The company addresses a critical vulnerability in widely used public key encryption like Rivest, Shamir, Adleman (RSA), which experts predict could be broken by increasingly powerful quantum computers within five to ten years. VeriQloud offers solutions for data at rest, in transit, and in use, focusing on proactive security for a future where quantum computing power becomes readily accessible. According to Didier Guignard, VeriQloud’s head of business and research development in North America, “Quantum computers will be high-powered processing units accessible via clouds,” emphasizing the need to secure data even as it’s being transferred and stored remotely.
Qasmat Secures Data at Rest via Data Share Splitting
A novel approach to data security splits information into fragments, safeguarding it against future quantum attacks. VeriQloud is addressing the looming threat to data at rest with Qasmat, a solution that fundamentally alters how stored information is protected. Unlike traditional encryption reliant on mathematical complexity, Qasmat proactively mitigates risk by dividing data into multiple “shares” before encryption, distributing these pieces across various storage locations. This strategy introduces a layer of resilience designed to withstand the anticipated processing power of quantum computers, expected to mature within five to ten years and potentially render current methods like RSA vulnerable. Guignard states, “When a third party wants to get to your original data, it doesn’t exist as a whole anymore as it has been split into shares that are stored in multiple locations.”
This dispersal buys critical time; any unauthorized access to one storage point triggers alerts, allowing for intervention before the complete data can be reassembled. The number of shares required to reconstruct the original data is fully customizable by the client, offering a scalable security profile. Qasmat distinguishes itself by avoiding reliance on potentially vulnerable encrypted keys or complex mathematical techniques. Instead, the system focuses on physical distribution and access control, creating a barrier to entry that is independent of algorithmic strength. This approach is particularly relevant given the emerging threat of “Harvest Now, Decrypt Later” attacks, where encrypted data is intercepted and stored for future decryption once quantum computers become sufficiently powerful. By fragmenting the data, VeriQloud aims to render such intercepted pieces useless without access to a sufficient number of shares. Guignard further clarifies, “The more you want to protect your data, the more shares you generate to prevent the rebuilding of your original data.” This proactive strategy positions VeriQloud as a key player in the evolving field of post-quantum data security, offering a tangible solution to a challenge that is rapidly gaining urgency.
Rather than a household item, quantum computers will be high powerful processing units accessible via clouds. When we are sending data to the cloud, we want to make sure that it is secure from any unintended recipients and from the quantum computer itself.
