Method for Secure Self-Booting of an Electronic Device

A self-booting device, the device comprising:

• one or more interfaces (115);
• one or more external components (103) being accessible through the one or more interfaces (115);
• a POR engine (111) adapted for determining a boot mode for booting the electronic device (101), wherein the determined boot mode is defined as a secure boot mode;
• wherein the POR engine (111) is further adapted for disabling the interfaces (115), thereby prohibiting access to the components (103) through the interfaces (115), thereby defining a secure state of the electronic device (101);
• a processing unit (109) adapted for loading a first code comprising a sequence of executable instructions to be executed by the processing unit (109) for booting the electronic device (101);
• the processing unit (109) being further adapted for loading a second code, the second code being encrypted;
• and for decrypting the second code and executing the second code, thereby enabling the interfaces (115) and switching the electronic device from the secure state to a debugging state.
