Low power elliptical curve encryption engine for electronic label rapid identity discrimination

Abstract

The invention belongs to the radio frequency identification technology field and particularly relates to a low power elliptical curve encryption engine for rapid electronic label identity discrimination. The ECC encryption engine comprises an arithmetic operation module, a register set module and a logic control module, wherein the arithmetic operation module comprises three sub modules of a finite field adder, a finite field multiplier and a finite field square arithmetic unit. Batch labels can be rapidly identified by employing the low power technology in combination with algorithm simplification, elliptical curve system configuration optimization and module realization; elliptical curve engine design can not only guarantee communication safety of labels and reader-writers, and design requirements in speed, area and power consumption can be further satisfied. The ECC encryption engine is suitable for realization schemes based on the Lopez-Daha elliptical curve system and the Montgomery step algorithm, effective support is provided for rapid false-proof verification on high additional value articles, and thereby article flow safety is enhanced.

Description

technical field [0001] The invention belongs to the technical field of radio frequency identification, and in particular relates to a radio frequency identification (RFID) tag encryption module, in particular to a low-power elliptic curve encryption (ECC) engine capable of quickly completing identification of radio frequency identification (RFID) tags. Background technique [0002] Passive UHF RFID technology has made great progress in recent years. Large devices with many components and high power consumption have been replaced by small area microprocessor chips with ultra-low power consumption. These low-cost RFID processor systems are widely used in logistics, retail, engineering manufacturing and electronic toll collection. In the foreseeable future, these systems will have broader application prospects. [0003] It is worth noting that in the above-mentioned applications, personal information, financial intelligence and some key data will be transmitted from the tag t...
