Design of Stable and Efficient Encrypted Packet Callback

Nowadays consecutive serial number callback or message callback based on time stamp is usually adopted in the design of encrypted message callback. However these two callbacks feature obvious defects and could not well meet the demand of software design. The continuous sequence number callback method requires fairly high hardware safety and reliability,process and send back the message in strict accordance with the message sequence,otherwise would easily lead to IPSec logic error. The callback method based on time stamp may consume more system resources and at the same time,it is not easy to set up the message timeout. Therefore,it is necessary to design a stable and efficient encryption packet callback method. The research on the design of encrypted packet callback indicates that by adding a specific message sequence number to the encrypted packet head,the defects of the above two methods could be effectively solved,thus satisfying the demand for stable,efficient operation of software.
