Abstract

Traditional public-key cryptographic schemes (RSA, ECC) are prone to attacks by Shor's algorithm, which makes them susceptible to future threats to sensitive information that is stored using productivity software applications. This paper aims to formally define the Secure Vault approach as a set of multiple modules of a productivity application that uses CRYSTALS-Kyber-512 (FIPS 203) for key encapsulation and CRYSTALS-Dilithium Level 2 (FIPS 204) as digital signature schemes. In this study, a systematic literature search of selected 19 articles from IEEE Xplore, ACM Digital Library, Scopus, and Google Scholar was performed according to 11 predefined inclusion/exclusion criteria. The CRYSTALS-Kyber-512 scheme generates keys within 0.05 ms and uses an 800-byte key—over 2,400 times faster than RSA-2048—providing NIST Level 1 quantum resistance based on Module-LWE. Complexity analysis proves O(2¹¹⁸) quantum security in QROM. The Secure Vault approach can be used to secure note-taking software, password managers, and task synchronization software.
