In this work, we introduce secureED, a protocol that tackles these limitations, resulting in a significant performance enhancement of approximately $2-24\times$ compared to existing methods. Our protocol computes a secure ED between two genomes, each
comprising $1,000$ letters, in just a few seconds. The underlying technique of our protocol is a novel approach that transforms the established approximate matching technique (i.e., the Ukkonen algorithm) into exact matching, exploiting the inherent
similarity in human DNA to achieve cost-effectiveness. Furthermore, we introduce various optimizations tailored for secure computation in scenarios with a limited input domain, such as DNA sequences composed solely of the four nucleotide letters.
