This paper addresses the security service
infrastructure included in the Controller Area Network
(CAN standard), proposing the incorporation of the
confidentiality service for that kind of network.
Regarding security currently CAN only supports a
special kind of service, namely safety, of data transfers
for error detection, signalling, and self checking.
Nevertheless, as CAN has become more diverse,
complex and integrated into other kind of networks, it
must provide higher security services, such as
confidentiality, quite specially for its bus which is the
most attack-prone point on CAN. Taking into account,
on one hand, the security services defined by ISO and,
on the other hand, the security services defined by
CAN, this paper proposes to incorporate the
confidentiality service to CAN based on RC4, which is
a lightweight symmetric stream cipher algorithm. The
paper presents then the clock cycles required for
encrypting different data sizes of the CAN frame in the
87C196CB, which is a microcontroller with integrated
CAN 2.0 serial interface.
