Smart Meter Remediation OVERVIEW It is the 2nd day on the job for you as a security professional. Your company makes electric meters and has installed them in the city of Pasco. These meters, each have a unique symmetric key, and use a radio wireless network to communicate with the control center. Due to the size limitations of the radio wireless network, the firmware must be segmented into packets and sent individually. It takes 1 second to send a firmware packet. There are two ways to send commands: 1. Unicast (one per meter) 2. Broadcast (all meters at once) You will develop a calculation engine to determine how long it will take to update all of a meter population's firmware. 1. The fastest way is to broadcast, but this is insecure. Why? 2. The most secure way is to unicast, but this is slow. Why? The city of Pasco has x meters: 25,000 meters and 1,000 packets (in 1 hr/hrs) Calculate the following and out the exact number of the calculation and show your work: 3. The broadcast time to remediate in hours. 4. The unicast time to remediate in hours. 5. The optimum time to remediate in hours
