Controller area network (CAN) is a popular and a very well-known bus system, both in academia and in

industry.

CAN

protocol

was

introduced

in

the

mid-1980s

by

Robert

Bosch

GmbH

[7],

and

it

was

inter-

nationally

standardized

in

1993

as

ISO

11898-1

[24].

It

was

initially

designed

for

distributed

automotive

control

systems

as

a

single

digital

bus

to

replace

traditional

point-to-point

cables

that

were

growing

in

complexity,

weight,

and

cost

with

the

introduction

of

new

electrical

and

electronic

systems.

Nowadays

CAN

is

still

used

extensively

in

automotive

applications,

with

an

excess

of

400

million
