Putting trust in your car

With cars getting more and more sophisticated and the worry about hackers moving on to attacking four-wheel targets, projects are underway to standardise communication pathways and protection methods, with the Trusted Platform Module being the core many manufacturers are gravitating towards, according to this article on EETimes Germany entitled Consumer electronics enforce automotive security discussion.

However, the article says:

In the discussion, many participants agreed that the processing power of available microprocessors is not sufficient to handle complex encryption schemes and that hardware accelerators such as TPMs are necessary to execute these tasks.

The TPM itself is not a hardware encryption accelerator, but I suppose cars these days are not equipped with gigahertz chips with 64 bit buses, so perhaps a TPM, being designed to handle encryption efficiently, can outpace the average car CPU?
