Problems solved by technology

The traditional TCP / IP network transmission mode lacks a built-in security mechanism. Generally, additional security enhancement technologies such as IPSec are used to solve network layer security problems. However, IPSec needs to perform packet-by-packet signature and authentication on transmitted packets, which has low efficiency. The chain network transmission model solves this kind of problem

Abstract

The invention provides a message chain terminal protocol stack construction method, a message chain terminal protocol stack analysis method, a message chain terminal protocol stack analysis device and a terminal.The construction method comprises the steps that a preset format of a message header of a message is obtained, and the preset format of an internet layer message header at least comprises a source SUI, a target SUI, a message chain newest node value and a serial number, or a source SEI, a target SEI, a message chain newest node value and a serial number; the method comprises the following steps: calculating a message chain latest node value corresponding to a current transmission message by using a message chain construction method, packaging the message chain latest node value and a corresponding serial number in an internet layer protocol data packet, and constructing an internet layer message; and the latest node value of the message chain and the serial number are compared and verified to ensure that the transmitted message sequence has the functions of packet loss retransmission and chain type synchronization.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method for constructing a message chain terminal protocol stack, an analysis method, a device and a terminal. Background technique [0002] The message chain is a security method for network data transmission proposed by the research team of Professor Jiang Wenbao of Beijing Information Science and Technology University. It follows the network transmission mode of the message chain protocol standard and becomes a chain network transmission mode. The traditional TCP / IP network transmission mode lacks a built-in security mechanism. Generally, additional security enhancement technologies such as IPSec are used to solve network layer security problems. However, IPSec needs to perform packet-by-packet signature and authentication on transmitted packets, which has low efficiency. The chain network transmission model solves this kind of problem. [0003] In order to support the chain...
