Abstract: A method and apparatus for securely booting software components in an electronic device to establish an operating environment are described herein. According to an aspect of the invention, software components are to be executed in sequence in order to establish an operating environment of a device. For each software component, a security code is executed to authenticate and verify an executable code image associated with each software component using one or more keys embedded within a secure ROM (read-only memory) of the device and one or more hardware configuration settings of the device. The security code for each software component includes a common functionality to authenticate and verify the executable code image associated with each software component. In response to successfully authenticating and verifying the executable code image, the executable code image is then executed in a main memory of the device to launch the associated software component.

Abstract: A method and apparatus for executing a first executable code image having a first version number into a memory of a device in an attempt to establish an operating environment of the device are described. The first executable code image retrieves a second version number from the second executable code image after successfully authenticating the second executable code image. If the first version number and the second version number do not satisfy a predetermined relationship, the second executable code image is prevented from being loaded by the first executable code image.

Abstract: A method and an apparatus for configuring a key stored within a secure storage area (e.g., ROM) of a device including one of enabling and disabling the key according to a predetermined condition to execute a code image are described. The key may uniquely identify the device. The code image may be loaded from a provider satisfying a predetermined condition to set up at least one component of an operating environment of the device. Verification of the code image may be optional according to the configuration of the key. Secure execution of an unverified code image may be based on a configuration that disables the key.

Abstract: A method and an apparatus for establishing an operating environment by certifying a code image received from a host over a communication link are described. The code image may be digitally signed through a central authority server. Certification of the code image may be determined by a fingerprint embedded within a secure storage area such as a ROM (read only memory) of the portable device based on a public key certification process. A certified code image may be assigned a hash signature to be stored in a storage of the portable device. An operating environment of the portable device may be established after executing the certified code.
