As a heuristic for this idea, suppose that, starting from a profile of sincere votes in the one-dimensional setting, voters who prefer the last- eliminated candidate, B, to the

Taking a modern processor with a clock frequency of 3.2 GHz, and a Detection Module able to process 16 clock cycles of information at the same time, we can use a FPGA running at

In our case, we measure the optimality in terms of achieving the same success rate as the optimal strategy (using the exact ML distinguisher derived according to the knowledge of

In this work we propose the Gossip NoC, a security en- hanced architecture to deal with single and distributed timing attacks. It is composed by a traffic monitor and a counter-

To execute this meta-gadget, the attacker must craft a packet that, as a result of a buffer overflow, overwrites the return address with the address of gadget1, and injects into
