1. a kind of method that End to End Encryption synchronizes, which is characterized in that the method includes:

  • Transmitting terminal generates first key stream with the synchronous code of key KEY and data packet to be sent through stream cipher algorithm, utilizes theOne key stream treats transmission data and encrypts to obtain ciphertext, sends the synchronous code and ciphertext;

    Receiving terminal generates the second key stream using KEY and the synchronous code through stream cipher algorithm, utilizes the second secret key decryption instituteIt states ciphertext and obtains data to be sent;

    The synchronous code is determined by the timestamp timestamp in real-time Transmission RTP packet header in data packet to be sent.
