A five-tuple authentication method for messages

Abstract

The invention discloses a message quintuple authentication method, wherein the method includes the steps of: reading information of a quintuple , and setting a unique ID value of the read quintuple according to an order; reading authentication information corresponding to one quintuple to be authenticated from an RAM, matching the quintuple to be authenticated with a corresponding ID value and performing authentication, and storing an authentication result in a state table; and searching an quintuple to be output in the state table through the ID value, and reading the authentication result of the authenticated quintuple. The message quintuple authentication method solves the problem that other quintuple authentication cannot be handled in an authentication process, and improves the quintuple authentication efficiency without the waste of resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for authenticating quintuples of messages. Background technique [0002] In network security, it is necessary to verify the legitimacy of the message by authenticating the five-tuple of the input message. No matter which authentication algorithm is required to read back data from the external RAM for comparison operations, the authentication result can be finally obtained. The entire authentication process It cannot be interrupted. At this time, even if a new message arrives and needs to perform quintuple authentication, it must wait until the previous quintuple authentication is completed. [0003] The existing quintuple authentication method does not allow new authentication to be carried out when a quintuple authentication is performed, and the external RAM needs to be read multiple times in the quintuple authentication. Due to hardware limitations, the...

Problems solved by technology

[0003] The existing quintuple authentication method does not allow new authentication to be carried out when a quintuple authentication is performed, and the external RAM needs to be read multiple times in the quintuple authentication. Due to hardware limitations, the read result needs to wait for several cycles to obtain. At this time, the internal logic is idle, and the external RAM bus is also idle, and the new authentication request cannot be responded to, resulting in a waste of system resources and a decrease in processing efficiency.
