摘要
为了实现木制品原料可追溯的目标,分析了2种供应链追溯架构,对比了多种追溯技术,选择了Mifare型号的RFIC卡作为追溯卡。通过位运算数学方法,计算获得权限设置码"F0FF0069",保证了凭KEYB可读写RFIC卡扇区信息,凭KEYA仅能读扇区信息,无权篡改。在实际应用中,KEYB由物流单位自行设定,可对管辖扇区自由写入物流日志;KEYA在社会公开,任何单位及个人均可无障碍地阅读物流日志,参加木材供应链的监管。该项设计能够阻绝盗砍滥伐的木材进入市场,能够证明木制品原料来源的合法性。
In order to trace the raw materials of the wood products, this paper analyzed two types of supply chain traceability framework and compared several traceability technologies. On this basis, Mifare RFIC card was eventually selected as the traceability card. The writing/reading permission setting code ＂FOFF0069＂ was obtained through bitwise operation method it ersured that： KEYB can read and overwrite the RFIC card sector information KEYA can only read but not overwrite the sector information. In practical applications, KEYB will be set by the logistics companies, which can be used to write the logis tics records on authorized sectors freely KEYA will be announced publicly and any individuals or organi- zations will be able to read the logistics records of the wood products and to participate in the supervision of the timber supply chain. This design will be able to deny the timber from illegal deforestation to enter the market and to prove the legality of the source of the raw wood materials.
