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.

19-year-old girl in Belthangady who attempted suicide dies in Mangaluru hospital
Belthangady: A 19-year-old girl from Belalu village, who had attempted suicide at home by consuming poison, has reportedly died at a hospital in Mangaluru.
The deceased, Rama, was the daughter of Dinesh and Revathi Naik of Mayada Balemandikallu in Belalu village, Belthangady taluk, and a II PUC student at Vamapadavu College.
Rama’s attempt to commit suicide is being linked to personal matters, as she is known to have loved a youngster.
On the night of April 19, she reportedly consumed rat poison at her residence and was admitted to a hospital in Mangaluru for treatment. After 10 days of treatment, she died on April 30 after failing to respond to medical care.
A case has been registered at the Dharmasthala Police Station, and investigation is underway.
(Assistance for overcoming suicidal thoughts is available on the state’s health helpline 104, Tele-MANAS 14416.)
