Chinese researchers hacked military-grade encryption algorithm using a D-Wave quantum computer, which breached the SPN algorithms.
A military-grade encryption algorithm has reportedly been hacked by Chinese researchers using a D-Wave quantum computer. This is being claimed as the first successful quantum attack on widely used encryption algorithms. This type of hacking poses a significant threat to military and finance like sectors.
Initially designed for non-cryptographic usage, the D-Wave Advantage system used in the process breached the Substitution-Permutation Network-structured algorithms.
The quantum annealing algorithm is incorporated, and the Babai algorithm’s rounding direction is adjusted leveraging the quantum tunneling effect for precise vector determination, according to researchers. “Leveraging the exponential acceleration capabilities of quantum computing, we address the challenge by computing two rounded directions for solutions on each bit of an N-dimensional lattice. This enables the realization of an exponential solution space search, a capability beyond the reach of traditional computing methods,” saidThe quantum annealing algorithm works like guiding a ball to find the lowest point in a terrain with hills and valleys.
However, in the quantum world, thanks to the quantum tunnelling effect, the ball can directly tunnel to the lowest point. Thus, the quantum annealing algorithm can quickly approach the best overall solution, according to the Chinese publication.Prabhat, an alumnus of the Indian Institute of Mass Communication, is a tech and defense journalist.
