摘要
RFID技术已经在集装箱管理、生产线调度、食品追踪追溯等一些领域取得成功应用,并引起广泛关注,这是由RFID的技术特性决定的,但同时,RFID的技术特性在数据传输速率、成本与安全方面却存在着难以调和的怪圈。
The essence of RFID should be relegated to be a sort of a fresh new way and mode of commercial data acquisition, cost of RFID’s data transmission and safety have gradually become appliance’s bottlenecks and aroused extensive attention of supply and requisitioning parties. Today, as for every section of RFID’s process, there might exist hidden danger of safety among which RFID is adopted by supply-chain products for providing information-sharing fundamental facilities and object name service, and some areas involved in tags, network and data will face the same problem. The author suggests:to strengthen RFID’s safety, one has to start with the following aspects such as symmetric-key cryptography for tags, read-only tags, physical damages, RFID reader’ s authentication and standards for new treaties, etc. The author approaches the diffi cult points of application from different angles.
