问题
I have an application for Android wear. I use GoogleApiClient to send message between Android wear and smartphone.
Is this communication safe? Is it safe to send sensitive data between devices, like password? Maybe I have to protect the data in some way?
Send message looks like this:
Wearable.MessageApi.sendMessage(googleApiClient, nodeId, path, message.getBytes()).await();
回答1:
According to the documentation:
A message is private to the application that created it and accessible only by that application on other nodes.
Although the underlying Bluetooth connection is encrypted it is considered to be breakable. However, I'm not aware of detailed information if and how exactly the communication is secured on a higher level.
