Today the cyber security is very present, especially in a context of technological advent only with the threat of virtual wars. For this reason, scientists at MIT in the United States have created a chip computer capable of preventing attacks cybercriminals who manage to divulge information hidden in mobile devices such as watches, cell phones, tablets or smart bracelets.

O chip is a novelty in the technological market because it is differentiated by the possibility of accessing private data that can be stolen using an agent called “side channel attack”. THE tactical collects information from a system or its Equipmentmonitors fluctuations in power consumption and thus obtains the data that needs to be protected.

“In movies, when people want to open locked safes, they hear the click of the lock as they turn it to see if they are on the right track. This is what a side-channel attack does by exploiting information leaking from these gadgets then use them to predict what is happening inside the device,” says electrical engineering student Saurav Maji, lead author of the study.

“Using this low-power method, the leak of device information is random every time and does not reveal any real side-channel information. The only problem is that this approach is more computationally expensive because the neural network has to perform more operations and also requires more memory to store this data,” adds Maji.

“We are at the point where safety is most important. We must be prepared to exchange a certain amount of energy consumption to make computing safer. Bearing in mind that future research could focus on how to reduce the amount of overload to do this calculation even safer,” concludes Professor Anantha Chandrakasan, co-author of the study.
