Fecha de publicación: 06/09/2019 Fuente: Wipo "IOT" The present technical solution relates to the field of organizing network data exchange between a plurality of devices, in particular for data exchange between internet of things (IoT) devices. The technical result is to increase the protection of information data exchange between devices by organizing a trusted execution environment and providing each participant in the information exchange in the trusted execution environment with a protected security module, within which all operations necessary for data exchange are carried out using a set of symmetric keys for access. The claimed solution is implemented by providing a trusted execution environment for the exchange of data packets between IoT devices, in which each of the IoT devices is equipped with a security module containing symmetric sets of keys used for encrypting, signing and checking transmitted data packets.
