摘要：
In order to solve the security problem of ECC cryptosystem, the security deficiency of elliptic curve encryption is described firstly in this paper. Then, the method of OAEP (Optimal Asymmetric Encryption Padding) in the random oracle model is adopted to enhance the security of the existing ECC encryption system. An improved encryption padding scheme for ECC cryptosystem, namely EOAEP (ECC OAEP), is proposed and designed in this paper, Under the one-way assumption of encryption function, it has been proved that our scheme satisfies adaptive chosen ciphertext security by using the Game-Hopping technology according to the random oracle model.
