An RFID Authentication Protocol Suitable for Batch-mode Authentication

Passive Radio Frequency Identification (RFID) tags are nowadays used in stores and industries. These RFID tags are heavily constrained in computational and storage capabilities, Supply-chain, inventory management are the areas where batch-mode authentication of RFID tags is required in a secure and cost effective manner. The reader needs to forward to server a small number of messages corresponding a large number of tags to keep the communication cost as low as possible. Gene Tsudik proposed a trivial RFID authentication protocol named YA-TRAP* [1]. Our proposal improves the efficiency of the aforementioned technique in a cost effective way specially for batch-mode. The tag to reader and reader to server communication costs are reduced maintaining the same level of security. Moreover, a tag is helped by a reader to get operative from a non-operative state.

无源射频识别（RFID）标签如今在商店和工业中得到应用。这些RFID标签在计算和存储能力方面受到严重限制。供应链、库存管理等领域需要以安全且具有成本效益的方式对RFID标签进行批量模式认证。读取器需要向服务器转发少量对应大量标签的消息，以使通信成本尽可能低。Gene Tsudik提出了一种名为YA - TRAP*[1]的简单RFID认证协议。我们的方案以一种具有成本效益的方式提高了上述技术的效率，特别是对于批量模式。在保持相同安全级别的情况下，降低了标签到读取器以及读取器到服务器的通信成本。此外，读取器帮助标签从非工作状态变为工作状态。
