Method and system for receiving mobile streaming media conditions

The invention discloses a method for receiving mobile streaming media conditions, which comprises the following steps: 1) local self authorization, namely a client encrypts and stores a segment of password set by a user self at a local memory, and the segment of password is requested for inputting for checking when the client is started; 2) remote authorization, namely the client sends the information of the user to a server for verifying, and the remote authorization is considered to pass when the sent user information is matched with the user information stored in the server; 3) key distribution, namely the server encrypts a scrambling-descrambling key by adopting an RSA algorithm and then transmits the scrambling-descrambling key in a wireless channel so as to realize the key synchronization of the client and the server; and 4) video scrambling and descrambling, namely after receiving the scrambled streaming media data sent by the server, the client descrambles the streaming media data by using the descrambling key and then decodes and plays back the streaming media data, wherein the video scrambling means to change the video media data through a scrambling rule so as not to identify the received data, and the video scrambling can be implemented through multiple modes such as grouping encryption, stream encryption and the like.
