Abstract

According to one embodiment, a mobile communication apparatus includes a communication module and a main module. The communication module is capable of storing only one of an MQTTS certificate and an HTTPS certificate. The main module is capable of storing both the MQTTS certificate and the HTTPS certificate. The main module provides the MQTTS certificate to the communication module if the communication module starts MOTTS communication. The main module provides the HTTPS certificate to the communication module if the communication module starts HTTPS communication in a case where the communication module performs the HTTPS communication during a keep-alive interval of the MQTTS communication and provides the MQTTS certificate to the communication module if the communication module stops the HTTPS communication.
