Abstract
Embodiments of the present invention provide method for implementing security-related processing on packet and a network security device. Through establishing a relationship between stream attribute information of an initial packet of a stream and security-related processing information implemented on the initial packet, when a succeeding packet of the stream is received, the previously stored relationship is acquired according to stream attribute information of the succeeding packet, the security-related processing is implemented on the succeeding packet according to the security-related processing information in the relationship. Therefore, according to the method for implementing security-related processing on packet and the network security device provided by the present invention, the process of searching for security information entries for succeeding packets of a stream is not required, the security-related processing procedure of the packet is thus accelerated, and the packet processing efficiency is improved.
