How to provide Authorization of Devices in servicebus event hub

Hi

I am new to window azure ,Actually I want to send multiple machine data to azure servicebus EventHubby creating only one Eventhub. But I want that at the time of receiving data from event hub only a specific machine read their own data, Not another machine will read their data. Because my security is breeched by reading another's machine data. So this is possible or not in evethub.my code is here:--

EventHubClient eventHubReceiveClient = EventHubClient.CreateFromConnectionString(GetAmqpConnectionString(), EventHubName);
var subscriberGroup = eventHubReceiveClient.GetDefaultConsumerGroup();
EventHubDescription eventHub = NamespaceManager.CreateFromConnectionString(GetAmqpConnectionString()).GetEventHub(EventHubName);        
// Register event processor with each shard to start consuming messages
foreach (var partitionId in eventHub.PartitionIds)
{
  subscriberGroup.RegisterProcessor<DeviceEventProcessor>(new Lease()
  {
       PartitionId = partitionId,
  }, new DeviceProcessorCheckpointManager());
}
