All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The invention provides a side channel data processing method, which is used for reducing the accumulated power consumption in side channel data when a security chip is started and finished, expanding the detection range of the side channel data and improving the detection working efficiency, and the specific implementation steps are shown in figure 1 and are as follows:
step 101: sampling original side channel data of the security chip;
step 102: carrying out low-pass filtering on the original side channel data by using a low-pass filter to obtain trend curve data of the original side channel data;

In implementation, the security chip is a trusted platform module, is a chip capable of independently performing key generation and encryption and decryption, has an independent processor and a memory inside, and can store keys and feature data, thereby providing encryption and security authentication services for a computer. The security chip can encrypt the data stored in the security chip with high reliability, so that the data is difficult to steal illegally. Collision detection may be performed on the secure chip side channel data to determine the side channel attack resistance of the secure chip.
The side channel attack is a method for attacking the encrypted device against side channel information leakage such as time consumption, power consumption or electromagnetic radiation during the operation of the encrypted electronic device.
In implementation, since the security chip may have power consumption leakage, i.e., a power consumption accumulation effect at the start and end, the power consumption accumulation effect at each time is as shown in fig. 2, and the side channel data waveform collected after power consumption accumulation is less stable than the side channel data waveform collected by actual power consumption.
The side channel data waveform from start to end of a security chip is shown in fig. 3, and the above-mentioned power consumption accumulation effect is shown as start-time side channel data 301 and end-time side channel data 302, so that the collision detection between the side channel data of two stages of start and end of the security module and the side channel data 300 of the security module in stable operation becomes difficult.

In implementation, the operation period T of the security chip is a known working period of the security chip, or a working period of the security chip obtained by testing side channel data of the security chip during working according to a sampling clock during testing.
As an alternative implementation, if the number of operating cycles occupied by the security chip during the power consumption accumulation period is K, the cutoff frequency M of the low-pass filter is determined to be L/K, and L is the operating frequency of the security chip.
In an implementation, the operating frequency of the security chip is determined by the operating period T of the security chip, that is, the operating frequency L of the security chip is 1/T.
The low-pass filter can pass low-frequency signals, block high-frequency signals exceeding a cut-off frequency and smooth the side channel data, so that after the low-pass filter is used for low-pass filtering the original side channel data, a smooth trend curve data of the original side channel data can be obtained.
As an optional implementation manner, determining the number K of operation cycles occupied by the secure chip during the power consumption accumulation period includes:

As an optional implementation, preprocessing each raw side channel data includes:
averaging the power consumption accumulation end points of the data of each original side channel; or
And carrying out correlation analysis on each piece of original side channel data.

specifically, fig. 7 is a diagram in which correlation calculation is directly performed on side channel data without power consumption accumulation in the past when the security chip is started, a horizontal axis and a vertical axis in fig. 7 are time axes, an upper left corner in the diagram is correlation data of the security chip when the security chip is started, and it can be known from the diagram that the correlation data is affected by power consumption accumulation, so that colors in the diagram are unclear, and a side channel data collision detection effect between a starting stage and a steady stage after the starting stage is reduced, as shown in fig. 8, an effect of directly performing collision detection on the side channel data without power consumption accumulation in the past is as follows:
knowing that the point A and the point B are negative correlation conflicts, detecting the conflict between the point A and the point B at the point C, and judging that the point C has no conflict, namely, the point A and the point B are not detected;
