Abstract
A method for data exchange on a communication network, operating according to a protocol, and including a transmission bus, a first node and a second node. The first node carries out the steps of: constructing a first and a second data frame which transport first and second information data; calculating a first message authentication code as a function of the first and the second information data; constructing a third data frame which transports the first message authentication code; transmitting all of the data frames thus constructed. The second node carries out the steps of: receiving the first, the second and the third data frames; extracting the first and the second information data and the first message authentication code; calculating a second message authentication code as a function of the first and the second information data extracted; comparing the message authentication code extracted with the message authentication code calculated in order to verify the identity thereof.
