Abstract
A device with one-time-programmable (OTP) memory, boot code, volatile memory, and non-volatile memory. Boot code may use information in OTP to authenticate code of an implicit owner of the electronic device; receive a first create owner container request; create a first owner container comprising a first signed data image; store the first owner container; and use the first signed data image to authenticate first executable code associated with the first owner. Boot code may transfer ownership from the first owner to a second owner, including authenticating a signed transfer of ownership command using a key stored in the first owner container and creating a second owner container comprising a second signed data image associated with the second owner; storing the second owner container; revoking the first owner container; and using the second signed data image to authenticate second executable code associated with the second owner of the electronic device.
