摘要: 低成本无线射频识别(RFID)的标签是被动式的,由于受成本和资源限制,系统不能提供公约加密、对称密钥加密、杂凑函数等。EPCglobal Class-1 Gen-2 RFID规范定义一种低成本的标签,仅提供PRNG和CRC操作。该文遵循EPCglobal Class-1 Gen-2 RFID规范,仅使用PRNG操作设计一个认证协议,实现双向认证、标签的匿名性和前向安全性。

Abstract: Low-cost Radio Frequency Identification(RFID) tags are passive, on account of the limitation of cost and resources, can not afford the public key encryptions, symmetric encryptions, or even hash functions. EPCglobal Class-1 Gen-2 RFID specification defines the low-cost RFID tag which only can support on-chip 16 bit Pseudo-Random Number Generator(PRNG) and a 16 bit Cyclic Redundancy Code(CRC) checksum. In this paper, an authentication protocol conforming to EPCglobal Class-1 Gen-2 RFID specification only using PRNG is proposed, and it achieves tag-to-reader and reader-to-tag authentications, the anonymity of tag and forward secrecy.

Key words: low-cost Radio Frequency Identification(RFID), Pseudo-Random Number Generator(PRNG), authentication protocol
