Abstract
Examples associated with firmware encryption are described. One example device firmware includes a base module. The base module controls a base function of the device. The device firmware also includes a first encrypted module that modifies a first function of the device. The first encrypted module is inactive until decrypted. A decryption module decrypts the first module using a first encryption key and controls activation of the first encrypted module.
