Abstract

As a multireceiver variant of public key authenticated encryption with keyword search (PAEKS), broadcast authenticated encryption with keyword search (BAEKS) was proposed by Liu et al. (ACISP 2021). BAEKS focuses on receiver anonymity, where no information about the receiver is leaked from ciphertexts, which is reminiscent of the anonymous broadcast encryption. Here, there are rooms for improving their security definitions, e.g., two challenge sets of receivers are selected before the setup phase, and an adversary is not allowed to corrupt any receiver. In this paper, we propose a generic construction of BAEKS derived from PAEKS that provides ciphertext anonymity and consistency in a multireceiver setting. The proposed construction is an extension of the generic construction proposed by Libert et al. (PKC 2012) for the fully anonymous broadcast encryption and provides adaptive corruptions. We also demonstrate that the Qin et al. PAEKS scheme (ProvSec 2021) provides ciphertext anonymity and consistency in a multireceiver setting and can be employed as a building block of the proposed generic construction.

具有自适应损坏的关键字搜索的完全匿名广播认证加密的一般构造

broadcast authenticated encryption with keyword search (BAEKS)是public key authentication encryption with PAEKS (public key authentication encryption with keyword search)的一种多接收方变体，Liu等人(ACISP 2021)提出了该算法。BAEKS侧重于接收者的匿名性，其中没有关于接收者的信息从密文中泄露，这让人想起匿名广播加密。在这里，存在改进其安全定义的空间，例如，在设置阶段之前选择两个接收器的挑战集，并且不允许攻击者破坏任何接收器。在本文中，我们提出了一种基于PAEKS的通用BAEKS结构，该结构在多接收者设置下提供密文匿名性和一致性。提出的构造是Libert等人(PKC 2012)提出的用于完全匿名广播加密的通用构造的扩展，并提供自适应损坏。我们也证明了秦等人。PAEKS方案(ProvSec 2021)在多接收者设置中提供密文匿名性和一致性，可以用作提议的通用结构的构建块。
