Smart Meter

Developed as a project for the course 'Fundamentals of Information Security', the system processes smart meter readings and stores data on the recorded consumption. Security is achieved through the use of certificates, RBAC (Role-Based Access Control), and an event logger.

Built using

•   .NET 8

Installation:

1. Install .NET SDK:
   Download and install the .NET SDK 8.0 for your operating system from here.

2. Create and Install Certificates

1. Locate makecert.exe:
   Navigate to C:\Program Files (x86)\Windows Kits\10\bin and find the folder corresponding to your version (e.g., \10.0.22621.0\x86).

2. Open Command Prompt:
   Run Command Prompt as Administrator and move to the directory with makecert.exe:

   cd "C:\Program Files (x86)\Windows Kits\10\bin\10.0.22621.0\x86"

3. Generate Certificates:

• Self-Signed Certificate:

  makecert -n "CN=TestCA" -r -sv TestCA.pvk TestCA.cer

• Worker and LoadBalancer Certificates:

  Generate .pvk and .cer files:

  makecert -sv Worker1.pvk -iv TestCA.pvk -n "CN=Worker1" -pe -ic TestCA.cer Worker1.cer -sr localmachine -ss My -sky exchange

  makecert -sv Worker2.pvk -iv TestCA.pvk -n "CN=Worker2" -pe -ic TestCA.cer Worker2.cer -sr localmachine -ss My -sky exchange

  makecert -sv LoadBalancer.pvk -iv TestCA.pvk -n "CN=LoadBalancer" -pe -ic TestCA.cer LoadBalancer.cer -sr localmachine -ss My -sky exchange

  Generate .pfx Files:

  pvk2pfx.exe /pvk Worker1.pvk /pi 1234 /spc Worker1.cer /pfx Worker1.pfx

  pvk2pfx.exe /pvk Worker2.pvk /pi 1234 /spc Worker2.cer /pfx Worker2.pfx

  pvk2pfx.exe /pvk LoadBalancer.pvk /pi 1234 /spc LoadBalancer.cer /pfx LoadBalancer.pfx
