Where Cryptography Is Headed


Reports began surfacing in October that Chinese researchers used a quantum computer to crack military-grade AES 256-bit encryption. Those reports turned out to be wrong, but that did little to dampen concerns about what would happen if it was true. The looming threat of quantum computers breaking today's encryption, and the stockpiling of encrypted data in preparation for a time when it can ... » read more

Research Bits: June 25


Quantum on silicon Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) developed a platform to probe and control qubits in silicon for quantum networks, after an earlier discovery that defects in silicon could be used to send and store quantum information over widely used telecommunications wavelengths. The device uses an electric diode to manipulate... » read more

Addressing Quantum Computing Threats With SRAM PUFs


You’ve probably been hearing a lot lately about the quantum-computing threat to cryptography. If so, you probably also have a lot of questions about what this “quantum threat” is and how it will impact your cryptographic solutions. Let’s take a look at some of the most common questions about quantum computing and its impact on cryptography. What is a quantum computer? A quantum comput... » read more

Research Bits: June 4


Ultra-pure silicon Researchers from the University of Manchester and University of Melbourne developed a technique to engineer ultra-pure silicon that could be used in the construction of high-performance qubit devices that extend quantum coherence times. The highly purified silicon chips house and protect the qubits so they can sustain quantum coherence much longer, enabling complex calcul... » read more
