Abstract
A method and system for generating an encrypted and authenticated message for authenticating a first component of an electronic device as the originator of the message are disclosed. The method and system comprise encrypting a block of information based on a key associated with a second component of the electronic device to generate an encrypted block of information; accessing, from a memory of the first component, a previous version of a dynamic unique key, the previous version of the dynamic unique key being at least partially based on a original unique key; generating a current version of the dynamic unique key based on the previous version of the dynamic unique key; generating a message authentication code based on the encrypted block of information and the current version of the first dynamic unique key; and transmitting, to the second component, the encrypted block of information and the message authentication code.
