Digitalization and the development of artificial intelligence are transforming the classical model of territorial sovereignty. The transboundary nature of cyberspace creates a gap between states’ aspirations to control the national information domain and the decentralized logic of data flows. For Ukraine, this challenge is intensified under conditions of Russia’s hybrid aggression, where information operations are aimed at undermining statehood and identity. The purpose of the article is to provide a sociophilosophical and legal substantiation of a conceptual model of Ukraine’s informational sovereignty as an adaptivehybrid system, grounded in the principle of “sovereignty as responsibility” and compatible with human rights standards. The study demonstrates the evolution of informational sovereignty from a model of exclusive control to an approach in which the state acts as guarantor of citizens’ digital dignity and mental integrity. It substantiates the necessity of legal protection of identity against informational violence and proposes the regulation of jurisdictional conflicts through mechanisms of “digital federalism” and the integration of ethical principles into the design of information systems. The article develops an adaptivehybrid model of informational sovereignty that combines technological resilience, jurisdictional regulation of crossborder flows, and axiological protection of dignity and human rights. The Ukrainian experience illustrates the distributed nature of such sovereignty, where citizens become active subjects of information security through the cultivation of critical thinking and media resilience.
