Fuzzy identity-based encryption (FIBE) scheme is a kind of identity-based encryption (IBE) scheme, in which any user's identity is composed by a set of attributes and any ciphertext encrypted under identity ID can be decrypted by using a private key corresponding to identity ID′ if ID′ is close to ID as measured by some metric. Due to the error-tolerance property, FIBE scheme is very useful in real-world applications. However, most FIBE schemes are provable secure only in a weaker security model. In order to eliminate this problem, Ren et al. recently proposed a new FIBE scheme and proved that it is fully chosen-ciphertext secure in the standard model. Unfortunately, in this paper, we will show that their FIBE scheme is even not chosen-plaintext secure.
