Appl. No.:

13/632384

Inventors:

Peng Chen - San Jose CA, US

Assignee:

The Florida State University Research Foundation, Inc. - Tallahassee FL

International Classification:

G06F 15/16
G06F 11/30
H04L 29/08

US Classification:

709206, 709207, 726 22, 726 23, 726 24, 726 25, 726 1, 726 3, 713182, 713187, 713188, 713189

Abstract:

A method of detecting a compromised machine on a network. The method receives an email message from a machine on the network and classifies it as either spam or non-spam. A probability ratio is then updated, according to whether the message was spam or non-spam, by applying a sequential probability ratio test. If the probability ratio is greater than or equal to a first threshold, then the machine is compromised. If the probability ratio is less than or equal to a second threshold, then the machine is normal. The operations of receiving a message, classifying the message, updating the probability ratio, and indicating the machine is normal or compromised until the probability ratio is greater than or equal to the first threshold are repeated for a plurality of messages. Such repeated operations are performed on each of the messages one at a time, as each of the messages is received.

International Classification:

H05K 7/20
G03B 17/55
H04M 1/02

Abstract:

An electronic module includes an operational subunit, having upper, lower and lateral surfaces, and including one or more electronic components, which are adjacent to the lower surface of the operational subunit and generate heat when the module is in operation. A heat sink is disposed in proximity to the lower surface of the operational subunit. A heat spreader, including a continuous sheet of a heat-conducting material, is folded to wrap around the operational subunit so that a lower side of the sheet is interposed between the lower surface of the operational subunit and the heat sink and a lateral side of the sheet extends around at least one of the lateral surfaces of the operational subunit.
