Considering the safety and the efficiency to transport files containing of sensitive data through internet, an encryption scheme based on the digital envelope technology and digital signature technology is proposed. The file is encrypted by AES while the symmetric key is encrypted using ECC. To ensure data integrity and encryption efficiency, the file is also processed by SHA-1 to get its digest which is then be encrypted by ECC. Moreover, in order to process large files or massive data effectively, a parallel encryption algorithm is proposed. The experiment result shows it performs well and provides a higher encryption speed.
