Post-Quantum Cryptography: A Multi-layer Bottleneck Analysis

From the paper:“Advances in quantum computing have led the research community to develop new post-quantum cryptographic algorithms. While most efforts have focused on designing and analyzing the security of these algorithms, their integration into real-world systems demands a multi-layer performance analysis to identify and mitigate potential bottlenecks. Aligned with NIST’s post-quantum transition strategy, this work… Read more »

Reducing the Number of Qubits in Quantum Discrete Logarithms on Elliptic Curves

A paper that shows how elliptic-curve-based cryptography becomes increasingly vulnerable by QCs From the paper’s abstract:“Solving the Discrete Logarithm problem on the group of points of an elliptic curve is one of the major cryptographic applications of Shor’s algorithm. However, current estimates for the number of qubits required remain relatively high, and notably, higher than… Read more »
