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

Abstract

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.

Description

technical field [0001] The invention relates to an MD5 encryption device and encryption method for network synchronization messages based on time prediction, which can be applied to all fields of real-time MD5 encryption for network synchronization messages. Background technique [0002] The early MD5 was implemented by software, which took up a lot of processor time; and the implementation by hardware could not satisfy all applications: when encrypting network synchronization messages in real-time under Gigabit network mode, it always failed to achieve to the desired bandwidth. When performing MD5 encryption on a network synchronization message with a time stamp, the MD5 calculation always needs to be completed before the message is sent, and the calculation time of MD5 is relatively long, resulting in a failure to increase the bandwidth. Contents of the invention [0003] The object of the present invention is in order to overcome the problem that above-mentioned prior ...

Problems solved by technology

[0002] The early MD5 was implemented by software, which took up a lot of processor time; and the implementation by hardware could not satisfy all applications: when encrypting network synchronization messages in real-time under Gigabit network mode, it always failed to achieve to the ideal bandwidth

When performing MD5 encryption on network synchronization messages with time stamps, it is always necessary to complete the MD5 calculation before the message is sent, and the calculation time of MD5 is relatively long, resulting in the bandwidth cannot be increased
