Abstract:

A new anti-tampering tag authentication method was proposed in this paper. By combining the distributed watermarking embedded RFID tag technology and the tamper-proof technology, storing data with watermark in multiple tags in order, a multi-layered watermarking authentication structure was constructed to ensure the integrity of electronic tags. Besides, the one-time pad encryption scheme based on a random numbers table was adopted to encrypt the keys, protecting the data in channels. The method realizes its goals namely preventing the data from being tampered and avoiding data being leaked. To test the method, a prototype system implementing the method was built, and ideal results were obtained. The method can be applied to many realistic scenes such as commodity warehousing and commodity certificate security, not only ensuring data security but also reducing costs for avoiding the usage of advanced intelligent electronic tags, and can be applied to many other fields.

Key words: distributed RFID, digital watermarking, random key table, anti-tampering tag
