问题 Tom works at a large retail company that recently deployed radio-frequency identification (RFID) to better manage its inventory processes. Employees use scanners to gather product-related information instead of manually looking up product data. Tom has found out that malicious customers have carried out attacks on the RFID technology to reduce the amount they pay on store items. Which of the following is the most likely reason for the existence of this type of vulnerability?

选项 A、The company’s security team does not understand how to secure this type of technology.
B、The cost of integrating security within RFID is cost prohibitive.
C、The technology has low processing capabilities and encryption is very processor-intensive.
D、RFID is a new and emerging technology, and the industry does not currently have ways to secure it.

答案C

解析 C正确。RFID的常见安全问题是当数据从标签移向读者的时候会被截获并修改。尽管可以整合加密作为一种预防措施,但是这种做法并不常见,因为RFID是一种具有低速处理能力的技术,而加密是处理器密集的技术。
A不正确。因为它并不是这里的最佳答案。问题中的公司可能理解了RFID以及它常见的安全问题,但是安全性通常需要整合到RFID技术中。这意味着RFID产品的供应商需要将安全性整合到产品中,并且可用的安全解决方案通常比较局限,因为RFID标签和读者通常不具备执行所需加密功能所需要的处理能力。
B不正确。因为将安全性整合到RFID产品中的成本可能是一个因素,也可能不是。它通常归结于技术本身的局限性,而不是所需要的成本。
D不正确。因为它并不是这里的最佳答案。RFID已经出现了很多年,行业里的许多公司都理解它的工作原理和它存在的安全问题。将安全性整合到具有如此多局限性的技术中需要真正的需求和推动。在绝大多数情况下,通过RFID转换的数据都不是特别敏感,所以将安全性整合到RFID的需求并不是真正需要。随着RFID的发展,它更可能配备处理安全的对策,但是目前该行业还没有发展到这一阶段。
