Abstract:
This article addresses the critical issue of securing backup storage for
confidential data, a key concern in safeguarding the operations of critical
information systems dealing with extensive amounts of sensitive
information. The study proposes a novel cryptographic fault-tolerant backup
storage system for confidential data, leveraging cryptographic algorithms
and protocols. These protocols enable message encryption, ensuring
decryption is only possible after a specified time period. The proposed
system combines various distributed key generation protocols, proactive
secret sharing protocols, asymmetric encryption algorithms, and digital
signature algorithms. By employing such cryptographic protocols,
it becomes feasible to develop and implement a robust, fault-tolerant service
for backing up confidential data
