Cryptography in public administration: a comprehensive perspective

Abstract

This paper addresses the importance of information security in public administration, highlighting the role of cryptography to guarantee properties such as data integrity and confidentiality. It describes in detail public key infrastructures and provides an analysis of the DNIe and the Cl@ve system as examples of secure electronic identification, with multiple applications in public administration. Furthermore, it pays attention to the strategies developed by various international public administrations to implement cryptographic systems resistant to the emerging threat of quantum computing. On the other hand, in the current context, some applications of blockchain technologies are listed. In summary, this work provides an overview of some cybersecurity challenges in public administration and various cryptography-based advances, highlighting the importance of continuously adapting to evolving cyber threats and technological opportunities.
