This appears to be an improvement on Differential Power Analysis attack against a FPGA. Congrats to the guys who discovered it! It's interesting to note that in the DPA/SPA world the standard model of operation is to develop a new attack and then patent the countermeasures ;) It should be noted that this is "probably" not a backdoor in the traditional sense (intentionally planted by some nefarious government organisation), rather just bad, leaky design that has been identified by an improved attack methodology...
