  Securing Machine-to-Machine Communication with wolfSSL

  Machine-to-machine communication takes place between both wired and wireless systems all around the world every day. As stated here, “M2M uses a device (sensor, meter, etc.) to capture an ‘event` (temperature, inventory level, etc.), which is relayed through a network (wireless, wired or hybrid) to an application (software program), that...
