Quantum Computing: Researchers Evaluate Algorithms that Quantum-Proof Encryption
The development of ultra-fast quantum computers may bring the end of encryption techniques used commonly today.
While it’s not impossible to decrypt data stored by today’s encryption algorithms, it isn’t practical. Encryption security is based on the fact that the time needed to break the encryption and read the stored information would take too long. Data stored with 2048-bit RSA encryption would take 6.4 quadrillion years to decrypt using today’s computers.
But Quantum computers may change that. It is estimated that quantum computers will be able to break 2048-bit RSA encryption in just 8 hours. This has got a lot of people in the security world anxious. Quantum computing isn’t a practical reality just yet, but research and early experiments with the technology is advancing rapidly. Reliable quantum computing devices will likely be achieved within the next ten years.
New algorithms are being devised that will stump for an age of quantum computers. NIST, the U.S National Institute of Standards and Technology, is evaluating the viability of different post-quantum cryptography systems. 69 algorithms were submitted to the agency for evaluation and NIST has gone into a third round of testing with 15 of the most promising algorithms.
Dustin Moody, NIST mathematician, said that “at the end of this round, we will choose some algorithms and standardize them. We intend to give people tools that are capable of protecting sensitive information for the foreseeable future, including after the advent of powerful quantum computers.”
