Chip said to aid personalization
Toward a Stronger Defense of Personal Data
By MIT News February 25, 2022
Saurav Maji and colleagues at the Massachusetts Institute of Technology (MIT) have designed an integrated circuit chip that can thwart power side-channel attacks with less energy expenditure than common security methods.
The chip is based on threshold computing, which splits data into random components for individual processing by the neural network before assembling the final result.
Maji said information leakage from the device is always random, and can never expose any side-channel data. An optimization function reduces computing power by cutting the amount of multiplication needed to process data, and shields the network by encrypting the model's parameters.
This application-specific integrated circuit (ASIC) chip that can be implemented on an Internet of Things device to defend against power-based side-channel attacks.
