We propose two chosen ciphertext secure public key encryption schemes from the learning parity with noise problem. Currently, all existing chosen ciphertext secure public key encryption schemes from the hard learning problems are constructed based on the All-But-One technique, while our schemes are based on the Cramer-Shoup technique.
