增强隐私安全的实用方案RFID

Practical Schemes For Privacy & Security Enhanced RFID

Jaap-Henk Hoepman, Rieks Joosten

摘要:

RFID系统中适当的隐私保护非常重要。然而,许多已知的方案是不切实际的,因为它们使用散列函数而不是更硬件有效的对称加密方案作为有效的密码原语,或者因为它们在读取器处招致相当昂贵的密钥搜索时间惩罚。此外,它们不允许对标签进行动态的、细粒度的访问控制,以满足更复杂的使用场景。在本文中,我们调查这样的情况下,并提出了一个模型和相应的隐私友好的协议,有效和细粒度的管理访问权限的标签。特别是,我们提出了标签和阅读器之间的高效相互认证协议,该协议仅使用标签上的对称密钥加密技术,同时不需要阅读器端昂贵的密钥搜索算法,从而实现合理的隐私级别。此外,我们的协议能够从被盗的读卡器中恢复。

英文摘要:

Proper privacy protection in RFID systems is important. However, many of the schemes known are impractical, either because they use hash functions instead of the more hardware efficient symmetric encryption schemes as a efficient cryptographic primitive, or because they incur a rather costly key search time penalty at the reader. Moreover, they do not allow for dynamic, fine-grained access control to the tag that cater for more complex usage scenarios. In this paper we investigate such scenarios, and propose a model and corresponding privacy friendly protocols for efficient and fine-grained management of access permissions to tags. In particular we propose an efficient mutual authentication protocol between a tag and a reader that achieves a reasonable level of privacy, using only symmetric key cryptography on the tag, while not requiring a costly key-search algorithm at the reader side. Moreover, our protocol is able to recover from stolen readers.
