Chosen-ciphertext security from identity-based encryption. (English) Zbl 1138.94010
The present paper illustrates a CCA-Secure public-key encryption scheme which can be used in a real condition of chosen cipher text attacks. The article is very well structured and all the used techniques have a good bibliography and proofs. There are other techniques in information security which achieve the same aim, but the current exposed one has its own originality.
