Abstract

The invention relates to a communication device (110) for communicating data over a low power wide area, LPWA, communication network, wherein the communication device (110) comprises: a processor (111) configured to process data; a memory (113, 115) configured to store data; a radio (117) configured to transmit and/or receive data over the LPWA communication network; and a security system configured to operate one or more sets of logically separated security domains (111 a-c, 113a-c, 115a-c), including a first set of security domains (111 a, 113a, 115a), on the processor (111) and the memory (113, 115), wherein each set of security domains (111 a-c, 113a-c, 115a-c) comprises a processor security domain (111 a-c) and a memory security domain (113a-c, 115a-c), which are configured to interact with each other to provide at least one respective security function, wherein the security system is further configured to restrict access to the radio (117) to one or more selected sets of the one or more sets of security domains (111 a-c, 113a-c, 115a-c), including the first set of security domains (111 a, 113a, 115a), and wherein the processor security domain (111a) and the memory security domain (113a, 115a) of the first set of security domains (111 a, 113a, 115a) are configured to interact with each other for authenticating the communication device (110a) within the LPWA communication network.
