Embodiment Construction

[0035] The communication system, verification device, message identity verification and signature method provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] This embodiment firstly provides a signature and verification method of message identity, which is applied to a communication system composed of a signing device (such as a host, a resident gateway, etc.) and a verification device (such as an edge device of an operator network) . The signing device obtains the identity of the message to be signed, and the identity specifically includes the source IP address, the prefix of the source IP address, the source MAC (media access control) address, the link identifier, and the like. The link identifier includes VLAN, PVC, flow label, etc., obtains its corresponding shared keyword according to the identity identifier, uses the shared keyword to sign the message to be signed, and then sends the ...

Abstract

The embodiment of the invention provides a communication system, a verification device, and a verification and signature method for message identity, and relates to the technical field of communication. The invention provides a mobile access user terminal, and verification of message identity transmitted by the access user terminal in the form of PON and radio broadcasting. The system comprises a signature device and a verification device, wherein the signature device is used for transmitting a message carrying a first signature value; and the verification device is used for receiving the message, which carries the first signature value and is transmitted by the signature device, acquiring sharing key words for verifying the message, computing a second signature value of the message according to the sharing key words and comparing the second signature value with the first signature value, if the second signature value is equal to the first signature value, the message is valid, otherwise, the IP message is invalid. The technical scheme can be widely used in communication systems or computer networks.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication system, a verification device, and a message identity verification and signature method. Background technique [0002] In order to reduce the load on the network and eliminate hidden dangers in network security, the bearer network needs to verify the packets entering the network to prevent a large number of illegal packets from impacting and consuming the network and ensure that legal traffic packets can be carried smoothly. [0003] At present, the verification of the packet can be performed by means of IP address binding. For example: configure an address binding table on a node such as a DSLAM, when the node receives an IP message, check whether the source address of the IP message is bound in the address binding table, and if so, verify that the IP message is legal , allow the IP packet to pass; otherwise, filter out the IP packet. [0004] The invento...
