Improved Efficiency for CCA-Secure Cryptosystems Built Using Identity Based Encryption
Cryptosystems Built Identity Based Encryption
2015/8/5
Recently, Canetti, Halevi, and Katz showed a general method for constructing CCA-secure encryption from identity-based encryption in the standard model. We improve the efficiency of their construction...

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 ...
A Generic Construction of CCA-Secure Cryptosystems without NIZKP for a Bounded Number of Decryption Queries
Generic Construction CCA-Secure Cryptosystems NIZKP Decryption Queries
2008/12/30
In this paper, we propose a generic construction of chosen-ciphertext secure cryptosystems against adversaries with a bounded number of decrytion queries from arbitrary semantically secure encryption ...
