Method of securing and exposing a logotype in an electronic device

A method of accessing a secure logotype, the method comprising:

• re-calculating, in connection with a boot sequence of an electronic device, of a MAC value, thereby yielding a re-calculated MAC value;
• comparing a reference MAC value to the re-calculated MAC value;
• if the step of comparing results in a match between the reference MAC value and the recalculated MAC value, performing a first operation;
• and
• if the step of comparing does not result in a match between the reference MAC value and the re-calculated MAC value, performing a second operation.

A method of accessing a secure logotype, the method comprising:

• loading code adapted to use data relative to the logotype onto a first chip of an electronic device;
• verifying, via a public key, of authenticity of the loaded externally-stored code and the data relative to the logotype;
• and
• in response to the authenticity being verified, exposing the logotype.

An apparatus for securing a logotype, the apparatus comprising:

• means for storing data relative to the logotype to an electronic device;
• means for storing code to the electronic device, the code being adapted to use the data relative to the logotype to expose the logotype;
• and
• means for protecting at least the data relative to the logotype via a message authentication code (MAC).
