    Abstract: A microcontroller is provided and comprises a central repository, a processing device, and a firewall. Rule repository memory in the central repository stores one or more access rules defining an access permission of a software context to one or more target resources of the microcontroller. The firewall receives a bus transaction initiated based on an instruction and determines whether any access rule stored in memory of the firewall defines the access permission of the software context to a destination resource. If no access rule stored in the firewall memory defines the access permission, the firewall communicates a miss query condition to the central repository. The central repository searches the rule repository memory for an access rule defining the access permission of the software context to the destination resource, and if a related access rule is found, the related access rule is stored in the firewall memory.

    Abstract: A key fob includes a transceiver to send and receive signals, a memory to store a key fob identification (KFID), and a processor coupled to said transceiver and memory. The processor is to execute, along with a pairing device, an identification (ID) authenticated key agreement protocol based on the KFID to authenticate a pairing device and to generate a common secret encryption key known only by the processor and the pairing device. The Processor receives a control unit identification (CUID) encrypted by the pairing device with the common secret encryption key, execute along with the control unit associated with the CUID an ID authenticated key agreement protocol based on the CUID to authenticate the control unit, generates a second common secret encryption key known only by the processor and the control unit, and receives an operation key encrypted by the control unit with the second common secret encryption key.

    Abstract: A method for pairing a key fob with a control unit is provided. The key fob executes an ID authenticated key agreement protocol with a pairing device based on a key fob identification to authenticate one another and to generate a first encryption key. The pairing device encrypts a control unit identification using the first encryption key. The key fob receives the encrypted control unit identification transmitted from the pairing device. The key fob then executes an ID authenticated key agreement protocol with the control unit based on the control unit identification to authenticate one another and to generate a second encryption key. The key fob then receives an operational key transmitted from the control unit that is encrypted with the second encryption key.

    Abstract: A control unit, in a disclosed embodiment, includes a transceiver, memory, and a processor. The processor is coupled to the transceiver and memory and executes instructions from the memory to cause the control unit to receive a first transmission containing a certificate, verify the authenticity of the certificate, and, after verifying authenticity of the certificate, execute a public key agreement protocol to generate a first common secret encryption key, receive a second transmission containing an encrypted first public key that is encrypted by the first common secret encryption key, decrypt the encrypted first public key using the first common secret encryption key to determine the first public key, execute a public key agreement protocol to generate a second common secret encryption key, generate an operational key, encrypt the operational key using the second common secret encryption key, and transmit the encrypted operational key.
