Description

System and method for data integrity verification of a vehicle consist message Technical Field The present disclosure relates to the calculation and verification of data integrity associated with the exchange of one or more messages. Background The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. Before autonomous control of an automated vehicle, one or more messages are typically exchanged between the automated vehicle and a central server. If the exchange of messages is not properly protected, it may be compromised. For example, the data integrity of the message may be compromised. Additional threats may include a lack of synchronization procedures for checking whether the intended recipient has received each data bit, and a lack of functional methods for computing and/or verifying the payload associated with the message. The present disclosure addresses these and other problems associated with protecting the data integrity of exchanged messages in a vehicle consist system. Disclosure of Invention This section provides a general summary of the disclosure and is not a comprehensive disclosure of its full scope or all of its features. The present disclosure provides a method for initiating autonomous control of an automated vehicle, the method comprising calculating, by one or more processors of an infrastructure system, a first checksum value based on an infrastructure-side secret key and encoded data associated with the automated vehicle that is within a distance-related threshold from the infrastructure system, transmitting, to the automated vehicle, one or more infrastructure-marshalling messages comprising a second checksum value based on the first checksum value, receiving, from the automated vehicle, one or more vehicle marshalling messages comprising a third checksum value based on a vehicle-side secret key in response to the automated vehicle verifying the one or more infrastructure marshalling messages, and verifying one or more vehicle marshalling messages, wherein verifying the one or more vehicle marshalling messages comprises decoding the one or more vehicle marshalling messages, calculating, in response to the one or more vehicle marshalling messages, a fourth checksum value based on the vehicle-side secret key, and determining whether the fourth checksum value corresponds to the third checksum value, wherein calculating, in response to the automated vehicle, calculating, one or more vehicle marshalling messages further comprises calculating, by the one or more vehicle marshalling messages, associating, with the one or more vehicle marshalling messages, a third checksum value based on the vehicle-side secret key, and a constant associated with the one or more vehicle marshalling messages, wherein verifying one or more vehicle marshalling messages comprises decoding one or more vehicle marshalling messages, calculating, and associating one or more vehicle marshalling messages with the one or more data by a transform-side secret value and a constant associated with the one or more of the one or more vehicle marshalling messages, the method further includes determining a length of data associated with the one or more vehicle consist messages, wherein decoding the one or more vehicle consist messages further includes decoding a third checksum value, decoding the length of data associated with the one or more vehicle consist messages, and decoding the encoded data associated with the automated vehicle, wherein validating the one or more vehicle consist messages further includes transforming the decoded third checksum value by a transformation constant, recalculating a vehicle side secret key based on a vehicle side public key, recoding the one or more vehicle consist messages, and reconverting the transformed third checksum value by a transformation constant, wherein calculating a fourth checksum further includes appending the recalculated vehicle side secret key to the recoded one or more vehicle consist messages, and transforming the reconverted third checksum value by a transformation constant, wherein validating the one or more vehicle consist messages further includes determining whether the one or more vehicle consist messages associated with the recoded third checksum value corresponds to the length of data associated with the recoded vehicle consist message and further includes establishing a communication link between the third checksum value and the data associated with the automated method based on the length of the third checksum value.
