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 implement a real-time execution environment (112) based on a real-time operating system, wherein the real-time execution environment (112) is configured to execute a first instance of an application; 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 logically separated sets of 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 comprises a processor security domain (111 a-c) and a memory security domain (113a-c, 115a-c). The security system is configured to operate the respective processor security domains (111 a-c) of the one or more sets of security domains (111a-c, 113a-c, 115a-c) in parallel to the real-time execution environment (112), wherein the processor security domain (111 a) of the first set of security domains (111 a, 113a, 115a) is configured to execute a second instance of the application in response to the execution of the first instance of the application by the real-time execution environment (112).
