In an age when digital exchanges risk exposure to criminal and state actors, the challenge of sending information so that it stays hidden from everyone except the intended recipient, while also hiding who is speaking to whom, takes on increasing importance. A paper titled “Identity-Based Matchmaking Encryption with Enhanced Privacy Against Chosen-Ciphertext Attacks,” by Sohto Chiku, Keitaro Hashimoto, Keisuke Hara, and Junji Shikata, addresses this challenge directly by developing improved meth

Picture a locked box that anyone can see, but only you can open with a special key you keep hidden. That simple idea powers the security of nearly every cryptocurrency wallet, bank transfer, and secure online login today. A new 110-page analysis from Project Eleven warns that this everyday protection could crumble within four to seven years under the weight of an entirely different kind of machine: the quantum computer. The report, titled The Quantum Threat to Blockchains - 2026 Report, maps
Over the last several years, academia and industry have been converging on a shorter and more realistic timeline to Q-Day. While new research continues to move the Q-Day timeline up to 2028-2030, the scale and scope of the impact have been less clear. Broadly, the expectation has been that quantum attacks on cryptography would be serious, but there has been less information on which to base estimates of their speed, accessibility, and breadth. Two new research papers, released within a day of
The quantum technology landscape is rapidly evolving from speculative science to a tangible economic powerhouse, with experts forecasting a market worth up to $97 billion by 2035. According to a major McKinsey report, quantum computing, communication, and sensing could generate as much as $97 billion in global revenue within a decade, making 2025 a pivotal year in the transition from concept to deployment. McKinsey's analysis highlights a decisive shift in 2024, in which the focus shifted from
