Researchers have developed a new technique that allows hackers, the cancer cell of the digital age, to be detected 1,300 times faster than traditional encryption algorithms.
Researcher Zhen Song from Siemens, Europe’s largest technology conglomerate, said they discovered a new method that prevented hackers from stealing data during attacks.
“We have noticed that, given the security measures in modern industrial control systems, there is no way to protect information in real time,” said Song, because traditional encryption methods are not fast enough.
Stating that traditional encryption algorithms are too slow for industrial connections where the allowable delay is less than 1 millisecond, Song said, “It usually takes more than 100 milliseconds to process small amounts of data with traditional encryption algorithms.”
The new method developed by researchers at Siemens enables data to be transferred in real time over an unencrypted channel. But at the same time, a signal similar to “white noise” is transmitted through the same channel. White noise is a random signal with equal intensity at different frequencies in signal processing, giving it a constant power, spectral intensity. Used in many scientific and technical disciplines including physics, acoustic engineering, telecommunications, and statistical prediction, this method will allow experts to quickly detect cyber attacks by hackers in the background.
Indicating that this approach enables rapid detection of attacks, Song said, “When the attackers change or delay the channel signal a little in real time, the algorithm detects it and immediately alarms it,” he said. Indicating that the new technique is 32 to 1,300 times faster than traditional encryption algorithms, Song says that industry infrastructures can be protected much better with this method.
