Time-prediction-based network synchronization message MD5 encryption apparatus and encryption method

The invention relates to a time-prediction-based network synchronization message MD5 encryption apparatus and an encryption method. The encryption apparatus comprises a message receiving module, a message cache module, an MD5 algorithm module, a sending time prediction module, and a message sending module and is characterized in that the message receiving module and the message cache module are connected; the message cache module is respectively connected with the MD5 algorithm module, the sending time prediction module, and the message sending module; the message sending module is respectively connected with the MD5 algorithm module and the sending time prediction module; and the MD5 algorithm module is connected with the sending time prediction module. According to the invention, after starting, the sending time prediction module detects a current message and a next message continuously and predicts sending time of the next message by combining sending time still needed by the current message and calculation time needed for the MD5 encryption algorithm of the next message; after the sending time of the next message is obtained, the MD5 encryption algorithm is started immediately; and then the streamline operation is formed. Therefore, the MD5 encryption algorithm can be carried out successfully.
