Password mask method for enhancing attack resistance ability

ActiveCN104618094AEnhanced resistance to differential power attacksSave hardware resourcesEncryption apparatus with shift registers/memoriesAlgorithmPassword
The invention discloses a password mask method for enhancing attack resistance ability. The password mask method for enhancing the attack resistance ability includes an encryption process. The encryption process includes steps: (1) introducing an original random number X, and performing exclusive-or operation on a clear text; (2) performing IP (internet protocol) initial displacement, and then dividing the clear text into an L portion and an R portion, and furthermore introducing random numbers Xy and Xz, generated in the middle process; (3) introducing F functions amended by mask codes, and performing n turns of F function operation; (4) combining the L portion with the R portion, and then performing an FP inverse initial permutation; (5) introducing the original random number X, and performing the exclusive-or operation so as to obtain a cipher text C. The password mask method for enhancing the attack resistance ability can achieve different effects of the mask codes by only using two types of the F functions amended by the mask codes during the whole encryption and decryption process, and only needs to achieve two types of SM-Box, and compared with other schemes with CPA attack resistance, the password mask method for enhancing the attack resistance ability can save a great number of hardware resources and reduce cost on the premise of substantially enhancing differential power attack and related power consumption attack resistance.

Digital three-dimensional oscilloscope rapid acquisition system based on FPGA

The invention discloses a digital three-dimensional oscilloscope rapid acquisition system based on an FPGA. A to-be-measured signal is collected by the ADC module and then is stored in the data collection module through the point extraction module. A DTO _ FIFO is arranged in the data acquisition module, and reading and writing of the DTO _ FIFO are both controlled by the control module through acounter, so that the DTO _ FIFO can read the waveform data of the previous frame for mapping while storing the waveform data of the current frame. When the frame number of waveform mapping in the digital three-dimensional mapping module reaches a set value of the upper computer, the upper computer reads away a mapping result stored in the RAM, converts the mapping result into an RGB value and displays the RGB value in the display module. According to the invention, while the DTO waveform capture rate is improved, FIFO storage resources can be saved.
