Abstract

We present an inner-product matchmaking encryption (IP-ME) scheme achieving weak privacy and authenticity in prime-order groups under symmetric external Diffie–Hellman (SXDH) assumption in the standard model. We further present an IP-ME with Monotone Span Program Authenticity (IP-ME with MSP Auth) scheme, where the chosen sender policy is upgraded to MSP, and the scheme also achieves weak privacy and authenticity in prime-order groups under SXDH assumption in the standard model. Both of the schemes have more expressive functionalities than identity-based matchmaking encryption (IB-ME) scheme, and are simpler than Ateniese et al.’s modular ME scheme (Crypto’ 19). But our schemes only achieve a very limited flavor of security, which is reflected in the privacy.

产品内部匹配加密:双边访问控制和超越平等

在标准模型中，在对称外部Diffie-Hellman (SXDH)假设下，提出了一种内积配对加密(IP-ME)方案，实现了质数群中的弱隐私性和弱真实性。在此基础上，提出了一种IP-ME with Monotone Span Program Authenticity (IP-ME with MSP Auth)方案，将选择的发送方策略升级为MSP，并在标准模型的SXDH假设下实现了素阶群的弱隐私性和弱真实性。这两种方案都比基于身份的配对加密(IB-ME)方案具有更多的表达功能，并且比Ateniese等人的模块化ME方案(Crypto ' 19)更简单。但是我们的方案只能实现非常有限的安全性，这反映在隐私上。
