Abstract
A system may include a plurality of matching block cipher devices, and a hardware state machine communicatively coupled to each of the plurality of matching block cipher devices. Each of the plurality of matching block cipher devices can be independently invoked by the hardware state machine such that the hardware state machine causes two or more of the plurality of matching block cipher devices to selectively perform a block-cipher-based symmetric cryptographic operation in a redundant mode or a parallel mode. The block-cipher-based symmetric cryptographic operation may be associated with securing a communication channel of an automotive system.
