DEVELOPMENT OF PRACTICAL RECOMMENDATIONS FOR A DISTRIBUTED CRYPTOGRAPHIC KEY STORAGE SYSTEM BASED ON SHARDING SCHEME

Salikhov Maksim Ruslanovich

This article is dedicated to the development of practical recommendations for building a secure distributed cryptographic key storage system. A comparative assessment of resource consumption and system performance was conducted in relation to existing MPC solutions such as tss-lib, Partisia, and ZenGo X. The results confirm the practical applicability of the proposed recommendations in scenarios such as Web3, corporate key management, and digital legacy. The study offers valuable guidance for developers aiming to implement secure and scalable key storage solutions in the context of ever-increasing requirements for digital asset protection and cryptographic resilience. The paper also presents an architecture for distributed key storage with time-binding and integrity verification mechanisms, which is particularly relevant for ephemeral keys. The proposed model implements a flexible multi-scenario key recovery logic based on Shamir’s Secret Sharing (SSS) and ensures that access is impossible without user participation.
