We propose a practical public-key encryption scheme whose security against chosen-ciphertext attacks can be reduced in the standard model to the assumption that factoring is intrac...

Recently Cash, Kiltz, and Shoup [20] showed a variant of the Cramer-Shoup (CS) public key encryption (PKE) scheme [21] whose chosen-ciphertext (CCA) security relies on the computa...
