This 'black box' chip in devices can frustrate hackers
New York, May 14: In an era of Machine Learning (ML)-enabled hacking, in which Artificial Intelligence (AI) technology is trained to "learn" and model inputs and outputs, a new chip-based technology termed as a "black box" can thwart hackers' plans, say researchers.
According to Computer Science Professor Dmitri Strukov from the University of California-Santa Barbara, he and his team were looking to put an extra layer of security on devices.
The result is a chip that deploys "ionic memristor" technology.
Key to this technology is the memristor, or memory resistor -- an electrical resistance switch that can "remember" its state of resistance based on its history of applied voltage and current.
A circuit made of memristors results in a "black box" of sorts, as Strukov called it, with outputs extremely difficult to predict based on the inputs.
"You can think of it as a black box. Due to its nature, the chip is physically unclonable and can, thus, render the device invulnerable to hijacking, counterfeiting or replication by cyber-criminals," said Strukov in a paper which appeared in the journal Nature Electronics.
With ML, an attacker doesn't even need to know what exactly is occurring as the computer is trained on a series of inputs and outputs of a system.
"For instance, if you have 2 million outputs and the attacker sees 10,000 or 20,000 of these outputs, he can, based on that, train a model that can copy the system afterwards," said Hussein Nili, the paper's lead author.
The "memristive black box" can circumvent this method of attack because it makes the relationship between inputs and outputs look random enough to the outside world even as the circuits' internal mechanisms are repeatable enough to be reliable.
"If we scale it a little bit further, it's going to be hardware which could be, in many metrics, the state-of-the-art," Strukov noted.

Four held in Kalaburagi for brutal murder of man
Kalaburagi: Four men have been arrested in Kalaburagi on charge of hacking a man with lethal weapons and pelting stones at him under the limits of Station Bazaar Police Station recently.
According to police sources, Anand Jalak Shinde (34), Ashitosh Jalak Shinde (30), Imran Mehboob Sheikh (28) and Sohaib Anwar Qureshi have been arrested. The men are accused of the brutal murder of Syed Mehboob, a resident of Station Bazaar Upper Line Hamalawadi in the city.
An FIR was filed by the Station Bazaar Police Station based on a complaint given by Syed Ismail, father of the deceased Syed Mehboob.
Following quick probe, the police team successfully arrested the suspects within 24 hours. The arrested men were produced in court and have been sent to judicial custody.
The City Police Commissionerate has appreciated in an official release the police team’s quick solving of the murder case and arrest of the four men accused of murdering Syed Mehboob.
