A method of providing smart grid services securely via shared metering devices and a system derived thereof

A metering device (100) of electricity utility equipped with capability of providing internet access comprises a first sensors (400) capable of real-time measuring utility data of a first recipient (500) and the utility data is acquired as analog signal; a processor (110) connected to the first sensors (400) via a signal processing unit, which process and convert the analog signal to digital signal, to obtain the measured utility data for analysis through instructions from one or more software applications; a hypervisor (120) coupled to the processor (1 10) allowing the processor (110) to host a first (126) and a second operating system (125) forming a first subnet and a second subnet thereon; and a communication module coupled to the processor (110) and adapted to provide internet access to the first recipient (500) via a first domain connected to the first subnet and send the utility data to a billing server via a second domain connected to the second subnet.
