Abstract
We propose two constructions of chosen-ciphertext secure identity-based encryption (IBE) schemes. Our schemes have a security proof in the standard model, yet they offer performance competitive with all known random-oracle based schemes. The efficiency improvement is obtained by combining modifications of the IBE schemes by Waters [38] and Gentry [21] with authenticated symmetric encryption. © 2008 Springer-Verlag Berlin Heidelberg.
