Power consumption compensation anti-attack circuit and control method based on neural network power consumption prediction

Abstract

The invention discloses a power consumption compensation and attack resisting circuit based on neural network power consumption predication and a control method. The circuit is composed of an encryption and decryption module achieving an encryption and decryption algorithm function, a power consumption compensation circuit and a neural network prediction module, a neural network algorithm with adaptive learning capacity is adopted in the method to build a power consumption predication model, power consumption predication is carried out when a code circuit works, a configurable power consumption compensation circuit is built, the compensation circuit is controlled to carry out corresponding function configuration according to a power consumption predication result, the power consumption of the overall circuit tends to be a steady state value, the value is not changed along with the change of a secrete key and processed data, an intruder cannot acquire the dependency of the value and secrete key information, and therefore power consumption attack can be effectively resisted.

Description

Technical field [0001] The invention belongs to the field of information security, especially in the aspect of anti-power consumption attacks of cryptographic circuits. It is used to protect cryptographic circuits so that they can resist power analysis attacks with higher flexibility without reducing the processing speed of cryptographic circuits, and enhance The security of cryptographic circuits. Background technique [0002] With the increasing informatization, digitization and networking of modern society, people's demand for information security technology has become more extensive and in-depth, and information security products have become an important guarantee for the healthy operation of the entire society.
