201609-Challenges in radio communications for smart grids

= IoTSec work meeting =

Agreements
1. step
 * infrastructure analysis in Halden/Fredrikstad/Valer, e.g. transformators, switches, .. (DSO power network elements)
 * analysis of information flow, from distributed elements into
 * a) the SCADA control room
 * b) the cloud

2. step
 * assessment of parameters for security (e.g. timing, capacity, duty cycle,...)
 * threats to communications

= other discussions= Use case: moving security to the cloud -
 * home automation managed to the cloud
 * access in the home for devices
 * Moving the grid control to the cloud… (moving the scada system to the cloud)

Potential advances for cloud operation of security
 * costs

Starting point - Security of SCADA systems

Security assessment of cloud - distributed

Demand/Respons - high-frequency from other power grid elements

Communicaton challenges
Communication:
 * upcoming/new standards for IoT networks, e.g. SigFOX
 * communication often results in reliablity and DoS-like security aspects

existing 400 and 800 MHz communications, as used in current smart meters
 * restriction in capacity - check capacity of 800 and 400 MHz ISM bands
 * restriction in duty cycle, e.g. 1,5% duty cycle
 * coverage versus capacity (in a 300m circle, how many elements, e.g. smart meters)
