Abstract
We present a new public-key encryption scheme, and prove its adaptive chosen-ciphertext security under the gap hashed Diffie-Hellman assumption in the standard model. Compared with previous public key encryption schemes with adaptive chosen-ciphertext security, our proposed scheme simultaneously enjoys the following advantages: small public key size, short ciphertext, low computational cost, weak complexity assumption and public verifiability.KeywordsPublic key encryptionadaptive chosen-ciphertext securitygap hashed Diffie-Hellman assumption
