The invention discloses a mobile portable side channel acquisition and testing device and its control method. The device comprises: a target development board for power consumption acquisition, which is used to realize encryption and decryption, and output the original instantaneous power consumption; a curve preprocessing module, which is used to Preprocess the original instantaneous power consumption; the acquisition board compares the power consumption data after curve preprocessing with a given voltage threshold, outputs a binary signal, and performs cumulative counting through the threshold compression method, and the power consumption in the working cycle Convert the power consumption data into a power consumption compression value, store it, and draw a power consumption curve according to the power consumption compression value of each working cycle; the analysis board is used to set the given voltage threshold during the test and receive the power consumption sent by the acquisition board curve and perform differential energy analysis on it. The invention greatly compresses the power consumption data at the data collection stage, and does not rely on traditional oscilloscopes and PCs, can efficiently perform side channel analysis, and has the characteristics of light weight, portability, and low cost.
Description
technical field [0001] The invention relates to the technical field of password security, in particular to a mobile portable side channel acquisition and testing device and a control method thereof. Background technique [0002] Side-channel attack refers to the use of various side-channel leakage information during the working process of the circuit, such as: energy consumption, time, fault, electromagnetic radiation, etc. Realize the extraction of secret information. Side Channel Attack (SCA) targeting cryptographic chips or hardware circuits of cryptographic devices has become a major threat in the form of cryptographic algorithm hardware. [0003] In order to protect the security of cryptographic equipment, different organizations have developed side-channel analysis equipment for security testing of cryptosystems. Traditional side-channel data acquisition equipment consists of power supply, high-frequency digital oscilloscope, PC, and target cryptographic chip, and th...
