RFID 编码解析服务是一个查找服务,提供 RFID 编码与其对应物品的相关信息
存放地址的映射服务。RFID 编码解析服务主要可分为静态解析服务和动态解析服
务,静态解析服务提供的映射关系在编码分配阶段就可以确定,而动态解析服务提
供的映射关系是用一条地址链来描述,并随着关联信息的不断增加而逐渐扩充。现
有的动态解析服务有 EPC 组织提出的发现服务。发现服务可以使用户查找到有关依
靠产品电子编码标识的单一物理实体信息的多个资源。
由于发现服务提供的数据是分散存储在各个信息服务的机构中,要保证每个数
据来源的安全是比较困难的。为此,在 863 课题的引领下,本文提出一种面向供应
链的 RFID 动态解析系统。该系统针对供应链上各个角色的特点,选择生产商作为
信息服务的机构,将供应链相关信息存储在生产商的服务器上。该系统可以及时地
为各企业提供物流信息,在集中管理的基础上采用安全认证机制来保证数据的可靠
性。
本系统在 RFID 编码解析服务的基础上,研究并实现了一种面向供应链的动态
解析服务。本系统采用了证书认证、数字签名和安全传输等措施,同时用权限管理
来控制数据访问,保证了供应链的数据来源安全、可靠。
本系统能与静态解析系统集成,提供公共查询;又可单独为企业内部服务,提
供闭环查询。本系统的研究,对我国 RFID 的应用具有积极的推动作用。

ABSTRACT
RFID Code Resolution Service is a query service. It provides a mapping service for
RFID code and the address that memory the information about the goods. RFID Code
Resolution Service can be divided into two parts-Static Resolution Service and Dynamic
Resolution Service. The mapping relation provided by Static Resolution Service is
confirmed at the stage of distributing the code. The mapping relation provided by
Dynamic Resolution Service is described as an address chain, and the chain extends with
increase of information. anization has been researching a Dynamic Resolution
Service-Discovery Services. Discovery Services are envisaged to provide pointers to
multiple providers of information across a supply chain, to indicate the addresses of
information services of anizations that hold information about a given physical
object.
Because of the distributed storage for the datum provided by Discovery Service, it is
difficult to confirm the security of the datum. Therefore, the thesis provides a new
Supply-Chain-oriented RFID Dynamic Resolution System with the lead of 863 Project.
The system aim at the characteristic of roles in Supply Chain, set the manufacturer as the
organization of Information Service, and storage the information in server of
manufacturer. It can provide an information
