Abstract: First transistor logic is arranged by a first logic provider in circuit form and provides a minimum of functionality of the semiconductor device employed to bring up the semiconductor device, wherein the minimum of functionality is encrypted using a first encryption key. Second transistor logic is arranged by a second logic provider, different than the first logic provider, in circuit form to include security keys capable to perform cryptographic capabilities using a second encryption key. The second transistor logic further includes functionality that completes the semiconductor device as a chip device and is ready to process secure communication signals.
