Description

存储式电子标签安全应用及防伪鉴别方法 Storing electronic tag security applications and security authentication method

技术领域 FIELD

本发明涉及一种存储式电子标签安全应用及防伪鉴别方法。 The present invention relates to an electronic tag storing security authentication method and security applications.

背景技术 Background technique

射频自动识别(RFID)技术是国际上最近几年开始兴起并得到迅速推广应用的一门新技术。 Radio frequency identification (RFID) technology is internationally a few years and recently began to rise rapidly promote the use of a new technology. 它是为实现全球数字化而对物体的属性、状态、编号等特征数据进行自动采集所推出的一种全新手段,可广泛应用于人员、动物、物品的身份自动识别。 It is carried out automatically means a new collection launched on the properties of objects, status, number, and other characteristics of data to achieve global digital, can be widely used in people, animals, objects automatically identify identity. 如图1,射频自动识别应用系统主要由以下几部分组成:(1)存储标识物数据信息的电子标签(Tag),每张标签在制造生产时都被写上了不能修改的全球唯一的识别号(ID)。 1, a radio frequency automatic identification system consists of the following components: an electronic tag (1) store data identifier information (the Tag), the production of each label in the manufacturing are written on a globally unique ID can not be modified number (ID).

(2)用于识读及写入标签数据的读写器(Reader or Scanner)(3)用于对系统进行控制和管理的计算机硬件和软件(Computer)射频自动识别应用系统中采用的电子标签大多是存储式电子标签,如美国Amtech公司的IntelliTag500、SCS公司的Sahara RW9520等。 Computer hardware and software (Computer) (2) reader (Reader or Scanner) for reading and writing data to the tag (3) for control and management system for radio frequency identification tag application system used most storage electronic tag, such as the United States Amtech's IntelliTag500, SCS's Sahara RW9520 so on. 这些存储式电子标签对外表现为一个EEPROM存储器,主要用于存放被识别物体的特征数据。 The electronic tag memory is a EEPROM memory external performance, primarily for storing the recognized object feature data. 由于存储式电子标签本身不具有加密防伪功能,其上面存储的数据很容易被盗取,从而仿制出相似的存储式电子标签来以假乱真,这对自动识别应用来讲会造成严重的安全性问题。 Because storage electronic tag itself does not have encryption security features, data stored thereon can easily be stolen, so as to imitate a similar storage electronic tags to real ones, which automatically identifies the application in terms of cause serious security problems.

以停车场自动管理系统应用为例,目前开始流行的做法是为经常出入停车场的用户车辆发放远距离读取的月票卡(该卡即为存储式电子标签),每张卡上一般只存放该停车场内部规定的发放编号。 With automatic parking management system application, for example, became popular in the current practice is issued monthly card (the card is the storage electronic tag) for the remote reading of vehicle users frequented the parking lot, generally stored on each card release number specified in the on-site parking. 当贴有月票卡的车辆,每次进出停车场时挡杆自动抬起放行,提高了通行效率。 When the card is posted monthly vehicle, lever each time the parking lot and out of the lift automatically release, improve traffic efficiency. 显然,如果月票卡不采取安全措施,任一个用户从市场上购买一批停车场系统采用的同型号存储式电子标签和相应的读写设备,就可以仿制月票卡,从而可随意进入各个采用上述方案的停车场。 Obviously, if the monthly cards do not take safety measures, either a user to buy the same model stored electronic tag and a corresponding number of parking system uses the read-write device from the market, you can imitate monthly cards, which are free to access to all the above parking scheme.

具体实施方式 Detailed ways

下面结合附图和实施例对本发明作进一步的说明。 The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

一种存储式电子标签安全应用及防伪鉴别方法,其特征是:a、先由读写器生产商对读写器销售商(含集成商,由他们负责把读写器产品提供到最终用户手中)按行业进行编号,该编号称为厂商授权码(MAC-Manufacture Authorization Code),由厂商存入计算机数据库中统一管理,并将该编号在读写器销售前写入读写器中的存储单元中,该编号称为厂商授权码MAC,被写入编号的读写器就称为厂商授权后读写器,MAC码由生产商掌控;经过厂商授权后的读写器表面上没有任何区别,但由于内部存储的MAC码不同,因此可以很容易区分读写器属于哪个销售商,从而可保证不同销售商之间不能读取对方标签中的数据。 A storage security applications and electronic security tag identification methods, characterized by: a, start with reader manufacturers to reader vendors (including integrators, they are responsible to provide the reader product to the end user ) by industry number that called the manufacturer authorization code (MAC-Manufacture authorization code), by the manufacturer stored in the computer database and unified management, and the reader number is written in the memory cells before the sale of the reader , this number is called the MAC vendor authorization code, the reader is written into the called number after the companies authorized reader, the MAC control code provided by the manufacturer; the reader through the upper surface of the authorized vendors no difference, However, due to different internal MAC codes stored, and therefore can be easily distinguished reader belongs trader, which can ensure the data can not be read among other tags from different vendors.

b、仅有厂商授权码(MAC码)还不能解决同一个销售商提供给多个存储式电子标签发行者的读写器之间的互相可读取对方电子标签中数据的问题。 b, only the manufacturer authorization code (MAC code) is supplied to another does not solve the data can be read in the other between the electronic tag reader stores a plurality of electronic tag issuer issues the same vendor. 因此需要为存储式电子标签发行者对自己单位使用的读写器进行授权的途径。 Therefore we need to be authorized by way of its own reader unit used to store electronic tag issuer. 具体方法是:存储式电子标签发行者对从销售商处购买来的厂商授权后读写器使用读写器工具软件写入一个自己设定的密码,读写器自动将该密码写入读写器的另一存储单元中,此时,被写入该密码的读写器就称为两级授权读写器,该密码称为用户授权码UAC(UAC-User Authorization Code),UAC码由存储式电子标签发行者掌控;该密码只有射频自动识别应用系统(包括读写器及其相连的管理用计算机)的管理人员掌握,其他人员(包括销售商)不知道这个密码,由此保证同一个销售商的多个客户之间的互不侵犯。 The specific method is: after storing electronic tag issuer authorized to buy from a vendor at the vendor reader to use the software writes a reader tool set their own password, the password is automatically written to the reader to read and write another device in the storage unit, this time, the reader is written into the code is called the two authorization reader, the password is referred to as user authorization code UAC (UAC-user authorization code), UAC code stored by the electronic tag issuer in control; the password only radio frequency automatic identification system (including its management reader connected to a computer) managers to master, other personnel (including vendors) do not know the password, thus ensuring the same non-aggression between multiple clients vendors.

c、由存储式电子标签发行者对存储式电子标签进行防伪加密: c, security encryption for storage by the electronic tag storing electronic tag issuer:

(1)首先通过两级授权读写器用每张存储式电子标签条的ID号对厂商授权码MAC进行加密,生成加密后厂商授权码EMAC,将EMAC码写入存储式电子标签的存储单元中,并对该存储单元进行写保护;(2)其次通过两级授权读写器用每张存储式电子标签的ID号对用户授权码UAC码进行加密,生成加密后用户授权码EUAC,将EUAC码写入存储式电子标签的另一存储单元中,并对该存储单元进行写保护;d、系统实际应用时,用两级授权读写器对发行给使用者的每张存储式电子标签进行防伪鉴别:两级授权读写器首先读取使用者所持的存储式电子标签中的ID号,然后读取存储式电子标签中的EMAC码,对EMAC码进行解密后与两级授权读写器存储单元中存储的MAC码进行比较,如果不一致,则判定为不是该存储式电子标签发行者发行的存储式电子标签,如果一致,则继续读取存储式电子 (1) First, an authorization code by the MAC ID number two authorized access to the memory of each electronic tag Used strips vendor is encrypted, the storage unit generates the encrypted authorization code Manufacturer EMAC, EMAC code into the memory of the electronic tag and write protection of the memory cells; (2) followed by the authorized ID number two authorized access to the memory of each electronic tag Used for the user code is encrypted code UAC, after generating the encrypted authorization code EUAC user, the code EUAC another storage means stores the write electronic tag, and the write-protected storage unit; d, the practical application of the system, with two authorization issued to the user of the reader of each stored electronic security tag identification: two authorized user holds the reader first reads electronic tag storing the ID number, and then reads the stored electronic tag code EMAC, EMAC of the decrypted code with authorized access to the store two MAC unit stored code is compared, and if not, it is determined not to be stored in the electronic tag storing electronic tag issued by the issuer, if yes, continues to read the stored electronic 标签中的EUAC码,然后对EUAC码进行解密后与两级授权读写器另一存储单元中的UAC码进行比较,如果不一致,则判定为不是该存储式电子标签发行者发行的存储式电子标签,如果一致,则判定为是该存储式电子标签发行者发行的存储式电子标签。 Comparing the tag EUAC code, and then decrypt with two EUAC authorization code reader another UAC code storage unit, and if not, it is determined not to be stored in electronic memory of the electronic tag issued by the issuer label, if the agreement is determined to be stored in the electronic tag storing electronic tag issued by the issuer. 对防伪鉴别合格的存储式电子标签,还可对其它发行数据作进一步的判别处理,其判别方法不属于本发明内容之列。 Storing the security of identification of qualified electronic tag, may be further processed to other distribution data is determined, which does not belong to the column contents determination method of the present invention.

本发明的防伪鉴别判别过程流程图如图2所示。 Security authentication determination process of the present invention, a flow chart shown in FIG.

需要说明的是,对存储式电子标签的加密授权应在第一次使用标签之前,否则读写器拒绝识别该标签。 Incidentally, the encrypted license stored in the electronic tag should be used prior to the first tag, or the identification tag reader rejects. 当然,对已经经过本发明加密授权后的存储式电子标签可在使用过程中随时写入发行数据。 Of course, the electronic tag after the storage has been authorized by the present invention may be encrypted write data issued at any time during use.

使用存储式电子标签的ID号进行加密,是由于每张存储式电子标签的ID号的全球唯一性和永远不可更改性。 Use electronic tag ID number is stored encrypted, due to the globally unique ID number of each stored electronic tag and forever unchangeable nature. 这样可以保证即使标签中的其它所有数据都被复制,但数据解密后的结果一定和最初内容不一致,从而达到存储式电子标签的不可仿制特性。 This ensures that even if all the other tags in the data are copied, but the results and the first data decryption certain inconsistent, so as to achieve non-generic characteristic storing electronic tag.

本发明也可采用如下较为简便的安全应用和防伪鉴别办法:用存储式电子标签的ID号对厂商授权码(MAC)加密处理后生成厂商授权码EMAC并写入存储式电子标签存储单元中进行写保护,然后直接将写有EMAC码和发行数据的存储式电子标签发给用户使用。 The present invention may also be employed as the application is simple and safe way security identification of: storing the ID number with the electronic tag authorization code (MAC) generated vendor encrypted authorization code Manufacturer EMAC and write electronic tag storing unit for storing write protection, and then written directly to the storage electronic tag and release EMAC code data sent to users.

本发明还可采用如下较为简便的安全应用和防伪鉴别办法:用存储式电子标签的ID号对用户授权码(UAC)加密处理后生成加密用户授权码EUAC并写入存储式电子标签存储单元中进行写保护,然后直接将写有EUAC码和发行数据的存储式电子标签发给用户使用。 The present invention may also be used as a more convenient way to identify the safety and anti-counterfeiting applications: the user authorization code with the ID number stored in the electronic tag (UAC) generates the encrypted encryption and user authorization code EUAC electronic tag written in the memory storage unit write protection, and then written directly to the storage electronic tag EUAC code and release of data sent to users.

具体应用例:以RFS-1800系列读写器和RFT-9000系列电子标签的安全性解决方案为例:(1)厂商授权码MACMAC为一个4字节数,其中:第1字节(高) 厂商代码,固定为18H;第2字节 行业代码,规定如下:01-铁路车辆管理02-海关通道车辆管理03-小区停车场、厂矿企业、政府机关等单位车辆进出管理……第3-4字节 由生产商分配并管理的销售商顺序编号(2)用户授权码UAC最长8个字符,不足8个字符的用空格代替。 Specific application example: In RFS-1800 series reader and RFT-9000 series security solutions electronic tag as an example: (1) a manufacturer authorization code MACMAC 4 bytes, wherein: the first byte (high) vendor code, fixed at 18H; the second byte industry Code, provides as follows: 01- railway vehicle management vehicle management 03- 02- customs channel area, parking, industrial enterprises, government agencies and other units of vehicles entering and leaving management ...... 3-4 bytes are allocated and managed by the manufacturer, vendor sequence number (2) user authorization code UAC up to eight characters, instead of spaces with less than eight characters. 字符可以是0~9、A~Z、a~z和其它能从键盘输入的符号,字母区分大小写。 Character may be 0 ~ 9, A ~ Z, a ~ z, and other symbols entered from the keyboard, case sensitive.

(3)厂商授权码(MAC)被加密后写到电子标签的3号地址加密时把4个字节的MAC与标签ID号的低4个字节按位异或生成EMAC。 (3) Manufacturer authorization code (MAC) address is written to the electronic tag 3 when the lower 4 bytes of the encrypted four-byte MAC tag ID number generating EMAC bitwise XOR encrypted.

解密时把读取的EMAC与标签ID号的低4个字节按位异或后还原成MAC。 When the lower 4 bytes of the decryption EMAC tag ID number read by the bitwise XOR reduced to MAC.

(4)用户授权码被加密后写到电子标签的4号地址加密时把8个字符的UAC与64bits标签ID号的8个对应字节按位异或,再把结果的0~3字节与4~7字节相互异或,结果为4字节的EUAC。 (4) User authorization code is written to address 4 while the encrypted electronic tag encryption UAC and the tag ID number 64bits eight bytes corresponding to eight characters bitwise XOR, and then the result of bytes 0-3 4 to 7 bytes with each XOR result is 4 bytes EUAC.

解密时采用上述相同方法生成EUAC,与从存储式电子标签上读取的EUAC比较,来判别用户授权码的一致性。 Using the same method for generating the above-described decryption EUAC, compared with EUAC read from the electronic tag memory, discriminates the consistency of a user authorization code.

不论是厂商授权,还是用户授权均需要使用授权应用软件。 Whether companies authorized, or authorized users are required to use licensed software. 应用软件开发概要如下:一、厂商读写器发行管理软件厂商读写器发行管理软件只在生产厂商内部使用,绝不外流。 Application software development are summarized as follows: First, the issue of vendor management software vendor reader Reader issuance management software manufacturers use only internally, it will not be shared. 该软件具有下列功能:(1)软件自身安全机制◆登录:软件启动时,提示操作人员输入密码,只有通过验证后软件才能启动。 The software has the following features: (1) its own software security mechanism ◆ Log: When the software starts, prompting the operator to enter a password, and only after verification by the software to start.
