Post-quantum Digital Signature Scheme for Personal Data Security in Communication Network Systems

摘要

The reliable collection, processing and storage of the sensitive personal data constitute an important research topic in the European context, especially after the General Data Protection Regulation started to produce its legal effects. The data encryption has been the traditional way of ensuring the sensitive data is legitimately accessed. Nevertheless, traditional encryption systems have become vulnerable to quantum computer-based attacks. This fostered the research efforts that look for encryption schemes that are immune to quantum computers-based attacks. This paper describes one of the few digital signature schemes, which is essentially immune to quantum computers-based attacks. The optimized version of the scheme is offered in the article. This scheme is much more efficient than the original one and has the stronger security guarantees. Furthermore, it may run efficiently on traditional computer systems. The suitability of the proposed digital signature scheme is assessed using real-world data, which demonstrates that it can be used to secure large amounts of personal sensitive data.
