Abstract

Identity-based Matchmaking Encryption (IB-ME) is an extension notion of matchmaking encryption (CRYPTO 2019), where a sender and a receiver can specify an access policy for the other party. In IB-ME, data encryption is performed by not only a receiver identity but also a sender's encryption key. Nevertheless, previous IB-ME schemes have not considered the problem of efficient revocation. Hence, the authors introduce a new notion of revocable IB-ME (RIB-ME) and formalise the syntax and security model of RIB-ME. In particular, the authors give an effective and simple construction of RIB-ME in the standard model, whose security is reduced to the hardness of decisional bilinear Diffie—Hellman problem and computational Diffie—Hellman problem. In addition, the authors show two extensions of our RIB-ME scheme to consider chosen-ciphertext security and forward privacy.

标准模型中基于可撤销身份的匹配加密

基于身份的配对加密（IB-ME）是配对加密（CRYPTO 2019）的扩展概念，其中发送方和接收方可以为另一方指定访问策略。在IB-ME中，数据加密不仅通过接收方身份来执行，还通过发送方的加密密钥来执行。然而，以前的IB-ME方案没有考虑有效撤销的问题。因此，作者引入了可撤销IB-ME（RIB-ME）的新概念，并将RIB-ME的语法和安全模型形式化。特别是，作者在标准模型中给出了一个有效而简单的RIB-ME构造，其安全性降低到决策双线性Diffie-Hellman问题和计算Diffie-Hell man问题的硬度。此外，作者还展示了我们的RIB-ME方案的两个扩展，以考虑所选密文的安全性和前向隐私。
