Abstract
Some embodiments include a method for detecting and interrupting a cache-based side-channel attack. The method includes: (1) at least calibrating one or more chiplets of a network by calculating a threshold; (2) determining one or more device heartbeat vectors of the one or more chiplets, the one or more device heartbeat vectors being derived at least part from one or more measurements of activity of one of more dedicated security processors associated with the one or more chiplets; (3) determining that a particular chiplet of the one or more chiplets is being attacked with a cache-based side-channel attack, the determining being based at least in part on a computed disparity exceeding the threshold; and (4) employing countermeasures against the cache-based side-channel attack of the particular chiplet, the countermeasures including revoking one or more access rights of the particular chiplet on the network.
