AI Technical Summary

Benefits of technology

This patented method improves how fast algorithms work by adding an auxiliary bit called α (a type of constant) that helps decrease cycle time while still maintaining high efficiency compared to traditional methods like XOR or LUT operations. Additionally, this new approach can be used without increasing its size significantly because it does not require more circuitry than usual.

Problems solved by technology

This patented technical solution describes how securely transmitting data over networks can require both encryption keys (ciphertext) and identification certificates like passports or credit card numbers). These two types of things may also involve different mathematical techniques called modulo arithmetic and binary exponential function (BEV), but they work differently due to their importance towards maintaining privacy rights during transmission. To address this issue, these protocols use randomness instead of complex division functions while still ensuring strong protection against attacks from man-involved adversaries.

Abstract

The invention relates to the technical field of information safety, in particular to a low-energy-consumption small-area data processing method and a data processing device of the method. The low-energy-consumption small-area data processing method comprises the steps that large integers, the word length s of the large integers and constants are respectively stored; a control module receives external control commands, the external control commands are forwarded to a finite state machine module to be processed, then control signals are output, and Montgomery modular multiplication is carried out through an arithmetic logic module according to the control signals; HW=HW+d, X (s-1)=HW (omega-1:0) and HW=HW>=omega are calculated in each circulation of the Montgomery modular multiplication so that HW can be updated; multiply-add operation (d, ei)=a*bi+ci+d in the Montgomery modular multiplication is calculated through the arithmetic logic module; the operation result is stored. Due to the fact that omega+1 temporary variables HW are introduced in to reduce the circulation frequency in the process of achieving a Montgomery modular multiplication algorithm, the number of clock periods is reduced, energy consumption is lowered, and the method and device are very suitable for application of an intelligent card.
