METHOD, SYSTEM AND APPARATUS FOR SECURE TRANSMISSION OF MEDIA MESSAGE

摘要

Disclosed in the present invention are a method, system and apparatus for secure transmission media message. The method comprises the steps: a server generates a message corresponding to the media message, uses secret keys to encrypt the media message and the message respectively and obtain first and second encrypted information, and encrypt the secret key to obtain third encrypted information, and transmits the second and the third encrypted information. The receiver receives the second and the third encrypted information, and decrypts the third encrypted information with a private key to obtain the secret key, and then decrypts the second encrypted information with the secret key to obtain the message. The receiver accesses the server according to the message, and obtains the first encrypted information, then decrypts the first encrypted information with the secret key to obtain the media information. The method and the system of this invention can ensure the transmission of the media information in security.
