Crypto-Chips utilize state-of-the-art differential encoding schemes to encrypt stored information. These encryption algorithms make it possible to transmit identical data in any one of 64 billion different combinations without risk of duplication. The sheer number of possible transmissions make code breaking virtually impossible. Cryptographic semiconductor devices are ideally suited for automotive applications requiring ultra high security such as automotive lock and key entry systems. This paper describes in detail the advances in semiconductor cryptographic devices coupled with an in-depth explanation of resonance magnetic RF communication devices. The combination of these two technologies into a single semiconductor device will be presented as the latest achievement in automotive electronics combining ultra high security with passive customer vehicle interaction. Highlighted are automotive applications, which include passive remote keyless entry, engine immobilizers, and passive identification tags. For the covering abstract see ITRD E108169.
