论文摘要
基于身份的加密和平等测试支持灵活授权（IBEET-FA）允许对两个密文的潜在消息进行平等测试，同时通过允许用户（身份）控制其密文与他人的比较来增强隐私保护。 Ibeet本身具有广泛的有用域，例如在加密数据上进行关键字搜索，数据库分区，以进行有效的加密数据管理，个人健康记录系统以及在加密的电子邮件系统中进行垃圾邮件过滤。灵活的授权将增强对Ibeet的隐私保护。在本文中，我们基于错误（LWE）问题的学习硬度提出了有效的IBEET-FA系统的构造。我们的安全性证明在标准模型中。
Identity-based encryption with equality test supporting flexible authorization (IBEET-FA) allows the equality test of underlying messages of two ciphertexts while strengthens privacy protection by allowing users (identities) to control the comparison of their ciphertexts with others. IBEET by itself has a wide range of useful applicable domain such as keyword search on encrypted data, database partitioning for efficient encrypted data management, personal health record systems, and spam filtering in encrypted email systems. The flexible authorization will enhance privacy protection of IBEET. In this paper, we propose an efficient construction of IBEET-FA system based on the hardness of learning with error (LWE) problem. Our security proof holds in the standard model.
