New Stealth Address Protocols Improve Cryptocurrency Privacy

/ 1 min read

🧩 New post-quantum stealth address protocols enhance privacy in cryptocurrency. Researchers Marija Mikić, Mihajlo Srbakoski, and Strahinja Praška have introduced three novel stealth address protocols—LWE SAP, Ring-LWE SAP, and Module-LWE SAP—designed to be resistant to quantum attacks. These protocols utilize lattice-based cryptography, specifically the Learning With Errors (LWE) problem, to provide enhanced privacy compared to existing Dual-Key SAP (DKSAP) and Elliptic Curve Pairing Dual-Key SAP (ECPDKSAP), which are vulnerable to quantum computing threats. Notably, the Module-LWE SAP, leveraging the Kyber key encapsulation mechanism, demonstrates a significant performance improvement, outperforming ECPDKSAP by approximately 66.8% in the scan time of the ephemeral public key registry, marking a significant advancement in secure cryptocurrency transactions.
