Problems solved by technology

[0005] Although the asymmetric encryption algorithm has many advantages mentioned above, due to its complex calculation process, each encryption and decryption requires a lot of time and energy. Most of the existing asymmetric encryption methods focus on the research field of software, even hardware implementation. There are also many issues that need to be considered in system design

Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] The hardware block diagram of the elliptic curve encryption engine system is as follows: figure 1 as shown,

[0031] The encryption engine mainly includes three modules: arithmetic operation module (ALU), register bank module and arithmetic logic unit module.

[0032] The arithmetic operation module includes three main finite field operation subunits: finite field adder (ADD), finite field multiplier (MUL) and finite field square operator (SQR).

[0033] The finite field adder is based on the finite field addition operation. In the implementation scheme of the elliptic curve represented by the binary base, the realization of the addition operation is the XOR operation of a set of parallel register groups, which can be completed within one clock cycle;

[0034] The finite field multiplier is based on the simplified form of multiplication, and the...

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...
