Summary
This chapter provided a close look at BeagleBone capes and the CryptoCape. We intro-
duced the idea of trusted computing and built a biometric authentication system. We've
shown the normal use case for I2C devices and illustrated how one rogue device can cor-
rupt the entire bus.
In the next chapter, we'll use the BBB to protect e-mail encryption and signing keys for
Pretty Good Privacy
(
PGP
) and its free software implementation: GPG.
