Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as Figure 1-Figure 2 As shown, the algorithm needs to perform the following steps:

[0018] 1) In the standard FC-AE-ASM data communication frame format, sender data verification is performed

[0019] 2) Under the frame format of the standard FC-AE-ASM data communication, the data verification of the receiving end is performed

[0020] 3) If the comparison results are inconsistent, the data will be discarded.

[0021] The sending end data verification is to select the lower 32 bits of the D_ID of the FC protocol frame header, the RX_ID field, and the MSGID field of the ASM protocol frame header to be spliced ​​as the data verification field, and the 8th byte of the ASM frame header is used as the verification of the protocol field, the fourth byte in the ASM frame header is defined as the SN number, the fifth byte is d...

Abstract

The invention discloses a data encryption algorithm based on FC-AE-ASM protocol communication. The method comprises the following steps: 1) carrying out sending end data verification in a standard FC-AE-ASM data communication frame format; 2) carrying out receiving end data verification in the standard FC-AE-ASM data communication frame format; and 3) if comparison results are inconsistent, discarding the data. The method has the advantages that a new function of ASM protocol data verification is mainly realized, a newly added function is mainly used for realizing a data verification functionof an FC-AE-ASM protocol, adjustment is carried out in an FC and ASM protocol architecture, and the reliability of the whole system is not influenced. The data security of the fixed local area networkand the robustness of the network are ensured.

Description

Technical field: [0001] The invention belongs to the technical field of communication protocol data encryption, and relates to a data encryption algorithm based on FC-AE-ASM protocol communication. Background technique: [0002] In the airborne avionics system, the optical fiber network communication module of FC-AE-ASM protocol communication is mainly used as the terminal for data transmission and reception. All sub-systems under the entire avionics system use this protocol for data communication. [0003] At present, the optical fiber network communication module protocol based on the FC-AE-ASM protocol communication is based on the standard, so when the network is connected to a device that is not allowed to enter the network, data communication can be performed, which seriously affects the data security and security of the local area network. reliability. [0004] The problem to be solved by the invention is how to identify the devices that are not allowed to enter the...
