Abstract: Cramer and Shoup proposed the first provably secure practical public-key encryption scheme in the standard model (CS98). We find new way to construct the secure reduction in which the decryption oracle is not needed yet. Thus we get a simplified version of CS98 which is more efficient than the original scheme, and also provably secure against chosen ciphertext attack in standard model.
