Title:
Improved Efficiency for CCA-Secure Cryptosystems Built Using Identity-Based Encryption
Authors: Dan Boneh, Jonathan Katz
Abstract:Recently, Canetti, Halevi, and Katz showed a general method for constructing CCA-secure encryption schemes from identity-based encryption schemes in the standard model. We improve the efficiency of their construction, and show two specific instantiations of our resulting scheme which offer the most efficient encryption (and, in one case, key generation) of any CCA-secure encryption scheme to date.
