Methods, Systems and Computer readable Media for Detecting Convert Timing Channels

Description:

The method can detect cover timing channels by (1) reproducing the timing of every network output, (2) comparing the observed timing to the reproduced timing, and (3) issuing an alert if there is any discrepancy.

 

Inventor

Andreas Haeberlan, Raj and Neera Singh Assistant Professor

 

 

Penn researchers have built a time deterministic replay prototype called Sanity.  It reproduces timing to with 2% on commodity hardware.  It can be used to detect a variety of existing and novel covert timing channels with perfect accuracy. 

 

 

Advantages

When Sanity is compared with other detectors, 

All detectors can detect IPCTC with perfect accuracy, existing detectors do worse for more sophisticated channels, and existing detectors cannot detect "Needle in a haystack" well.  Sanity detects all channels with perfect accuracy!  No false positives, no false negatives.
