Abstract
Provided is a CAN communication based abnormal message detection method including obtaining reception times of reception messages; a reception filtering operation for performing a period calculation for comparing a difference between reception times of reception messages having the same message ID and a reference period of the corresponding message ID; an abnormal message detecting operation for determining the reception messages as abnormal messages when, as a result of the period calculation, the difference between the reception times is smaller than the reference period and determining the reception messages as normal messages when the difference between the reception times is greater than the reference period; and a blocking operation for blocking the abnormal messages.
