Indian researchers have built a low-energy security chip that is designed to prevent Side-channel attacks(SCAs) on IoT (Internet of Things) devices.<\/span><\/p>\n

What are Side-channel attacks(SCA)?<\/b><\/h5>\n

\"\"<\/p>\n

SCA <\/span>is a security exploit that aims to gather information<\/span> from the indirect effects of the functioning of the system hardware rather than attacking a programme or software directly.<\/span><\/p>\n

They basically aim to extract sensitive information like cryptographic keys, proprietary machine learning models and parameters by measuring things like timing information, power consumption and electromagnetic leaks of a system.<\/span><\/p>\n

For example, it can be used on a smartwatch to extract ECG and heart rate signals that one wants to keep secret.<\/span><\/p>\n

What have the researchers done to prevent SCA attacks?<\/b><\/h5>\n

Researchers have developed a low-energy security chip that is designed to prevent Side-channel attacks(SCAs) on IoT (Internet of Things) devices.<\/span><\/p>\n

The chip uses <\/span>near-threshold computing,<\/b> a computing method where the data is split into separate, unique and random components. The chip then conducts operations separately on each component in a random order before aggregating the results for a final result.<\/span><\/p>\n

Due to this method, the information leak from the device through power-consumption measurements are random and would reveal nothing but gibberish in an SCA.\u00a0<\/span><\/p>\n

What are the advantages and disadvantages of this chip?<\/b><\/h5>\n

Advantages<\/b>: It is smaller than the size of a thumbnail and uses much less power than traditional security measures against SCAs. It has also been built to be easily incorporated into smartwatches, tablets, and a variety of other devices.<\/span><\/p>\n

Disadvantages: <\/b>This method is energy and computation power-intensive, while also requiring more system memory to store information.<\/span><\/p>\n
