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 »
