A transposable identity enchainment system for diffuse identity management processing entities for each of users, data, and processes equivalently and having a recombinant access mediation system that mediates association among entities, an associational process management system that creates entity-defining indices, and a multi-dimensional enchainment system that enchains aspects of entity identities via mediated association certificates including at least one root certificate for at least one of the entities.

Diffusing a root identity of an entity among association and event covenants in a multi-dimensional computing security system involves generating a first generation of diffusion of identities of entities participating in mediated association and generating a second generation of diffusion of identities of the entities through recombinant mediated association of the entities and at least one other entity. The second generation of diffusion of identities facilitates securely constraining a computing system action associated with one of the entities.
