Zhenhua Chen, Shundong Li, Chunzhi Wang, Mingwu Zhang · International journal of network security · 2014
Recently, Fan et al. proposed an anonymous multireceiver encryption scheme (FHH) , and they declared that their scheme achieves confldentiality and anonymity. In this letter, We point out that the FHH scheme does not hold the deflned security properties. In particular, we state that the FHH scheme does not hold the anonymity but achieves the weaker confldentiality of IND-CPA.
