SecOC is the abbreviation of Security Onboard Communication, which is a new basic module added by AUTOSAR from Classic Platform 4.2, and its main function is to provide authentication and prevent replay attacks for data transmission on the automotive embedded network bus.
The SecOC mechanism requires that the SecOC module be implemented between the electronic control units (ECUs) that send and receive Protocol Data Units (PDUs).<\/p>

During the sending process, the SecOC module generates a secure PDU by adding authentication information to the original PDU of the protocol to be transmitted.
This authentication information includes Freshness Value (abbreviated as FV) and Message Authentication Code (abbreviated as MAC).<\/p>

The Freshness Value Management Module (FVM) is responsible for generating the FVs.The FVMs are divided into master FVMs (which are the responsibility of the gateway) and slave FVMs (which are the responsibility of other ECUs implementing the SecOC mechanism).
The former ensures that the FVs at the sending and receiving ends of the PDUs remain consistent by sending a Freshness Value Synchronization message to the latter, while the latter sends an FV Synchronization Request message to the former.<\/p>

The data identifier of the PDU, the original PDU, and the complete freshness value are concatenated together and then passed to the authentication algorithm to generate the MAC value.
After the receiver receives the secure PDU, it will be verified by the MAC authentication module to verify its freshness and integrity. If the validation is successful, the raw data PDU will be passed to the upper layer application software module; if the validation fails, it will be directly discarded.<\/p><\/div>\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t
