WebRTC - Western Illinois University Thesis

To Use

The signaling server uses Node.js and and can be started as such: ''' $ npm install $ npm start ''' With the server running, visit https://localhost:8443.

Three Different Cases, with an Effort to Establish Covert Channels to Promote Data Integrity using WebRTC

Cases

• Each case is done using an Acer laptop webcam with a webcam cover (black screen) to ensure consistent results.
• The test is conducted for 2 minutes (120 seconds), and during that duration low and high measurements are taken.
• First data is not recorded until 30 seconds have elapsed to ensure a consistent data stream has been established.
• Test is performed three times, each time having the client/server reset.
• The results are then averaged.
• All performed locally, simulating a Peer-to-Peer connection.

Case One: Establishing a Peer Connection, without Image Filtering or Random Delays

1. Takes Video Input, establishes a Peer Connection
2. Outputs to Remote Stream

Averages:

• Bitrate: 1128 kbits/sec
  • Low: 1008
  • High: 1248
• Jitter: 0.003 milliseconds
  • Low: 0.001
  • High: 0.005
• RTT: 0.009 milliseconds
  • Low: 0.006
  • High: 0.012

Case Two: Establishing a Peer WebRTC Connection, using Covert Channels with Image Filtering WITHOUT Random Delays

1. Takes Video Input and puts data to the First Canvas
2. Performs a data transformation, then outputs to a Second Canvas, then establishes a Peer Connection
3. Remote Connection senses the data transformation, reverses the transformation, and then outputs to the Remote Stream

Averages:

• Bitrate: 1643.5 kbits/sec
  • Low: 1385
  • High: 1902
• Jitter: N/A
  • Became unavailable with the use of canvas input and output.
• RTT: 0.0305 milliseconds
  • Low: 0.021
  • High: 0.040

Case Three: Establishing a Peer WebRTC Connection, using Covert Channels with Image Filtering AND Random Delays

1. Takes Video Input and puts data to the First Canvas
2. Performs a random data transformation, then outputs to a Second Canvas, then etablishes a Peer Connection
3. Remote Connection senses the random data transformation, reverses the transformation, and then outputs to the Remote Stream
4. This simulates data channel control by an administrator.

Averages:

• Bitrate: 1651 kbits/sec
  • Low: 1328
  • High: 1974
• Jitter: N/A
  • Became unavailable with the use of canvas input and output.
• RTT: 0.019 milliseconds
  • Low: 0.010
  • High: 0.028
