Summary/Abstract: Interoperability of government information systems is an essential pillar in the modernization of public administration, by facilitating data exchange between institutions, optimizing decision-making processes, and reducing information redundancies. Despite its transformative potential, the implementation of interoperability faces structural, technological, and normative challenges, which derive from the heterogeneity of IT platforms, the need to comply with the international legal framework (including GDPR), and the exponential complexity of cyber risks in the context of accelerated digitalization. In this sense, the article proposes an automated decision-making model for the contextualized selection of cryptographic algorithms, based on the use of the REPTree algorithm in the WEKA platform, capable of integrating measurable risk factors and recommending adapted cryptographic solutions (AES, RSA, ECC, SHA-256), thus contributing to strengthening cybersecurity in public IT infrastructures and to configuring a scalable, auditable and interoperable decision-making framework from a semantic and technical point of view.
