English Abstract	An identity-based encryption (IBE) scheme is called anonymous if the ciphertext leaks no information about the recipient's identity. In this paper, we present a novel anonymous identity-based encryption scheme. Our scheme comes from the analysis of Boyen-Waters anonymous IBE Scheme in which we find a method to construct anonymous IBE schemes. We show that Boyen-Waters anonymous IBE scheme can be transformed from BB1-IBE scheme. Our scheme is also transformed from BB1-IBE scheme and can be seemed as a variant of Boyen-Waters anonymous IBE scheme. The security proof shows the transformed scheme has the same semantic security as the original scheme and has anonymous security. We prove anonymity under the Decision Linear assumption. © 2011 Springer-Verlag.; An identity-based encryption (IBE) scheme is called anonymous if the ciphertext leaks no information about the recipient's identity.
