"CCA-Secure Identity-Based Matchmaking Encryption from Standard Assumpt" by Shen Lin, Yu Li et al.
Identity-based Matchmaking Encryption (IB-ME) is a new form of encryption that enables anonymous communication by specifying identities for both sender and receiver. Its applications in network services put forward higher requirements for the security of IB-ME. According to existing research, the security definition of IB-ME against chosen-plaintext attacks or chosen-ciphertext attacks is still vague. In this paper, we give the first clear definition of CCA-security of IB-ME and propose the first CCA-secure IB-ME scheme under the standard assumptions in the standard model. We first construct a...
