Abstract
The invention relates to a method and corresponding system for controlling, via secured transfers of tokens, operations of a plurality of interconnected devices having each a hardware trusted execution environment (TEE) and a controller, wherein each controller owns tokens attributed by a supervisor server and the TEE of each device is adapted to respond to a validation challenge via a zero-knowledge proof (ZKP) protocol, and generate and validate a single use ownership digital signature and its corresponding ownership signature validation challenge. The tokens can be transferred from one interconnected device to another in an online manner via a server or an offline manner via direct communication between the devices.
