Chinese researchers break RSA encryption with a quantum computer


The research team, led by Wang Chao from Shanghai University, found that D-Wave’s quantum computers can optimize problem-solving in a way that makes it possible to attack encryption methods such as RSA.

In a potentially alarming development for global cybersecurity, Chinese researchers have unveiled a method using D-Wave’s quantum annealing systems to crack classic encryption, potentially accelerating the timeline for when quantum computers could pose a real threat to widely used cryptographic systems.

  • Factorization Flaw in TPM Chips Makes Attacks on RSA Private Keys Feasible

    October 16, 2017

    A flawed Infineon Technology chipset used on PC motherboards to securely store passwords, certificates and encryption keys risks undermining the security of government and corporate computers protected by RSA encryption keys. In a nutshell, the bug makes it possible for an attacker to calculate a private key just by having a target’s public key. Security experts say ...

    Despite the immediate logistical demands of three catastrophic hurricanes in the last two months and various geopolitical flashpoints, cybersecurity remains a key issue and very much on the minds of top federal defenders. “There is no longer a ‘home game’ and an ‘away game,'” for homeland security, DHS Acting Secretary Elaine Duke said at a Sept. ...

  • Quantum Computing Would Make Today’s Encryption Obsolete

    July 20, 2017

    Quantum computing offers processing power so vast it may soon make today’s supercomputers look as crude as 1980s PCs. There’s a downside—the technology might also render the most secure encryption systems obsolete, cracking codes in a matter of minutes rather than months or years. Gregoire Ribordy says he has a solution. And it’s selling fast ...
