Two of the latest trends in semiconductor automotive designs are cryptographic security and radio frequency (RF) communication devices. 'Crypto-chips' utilise state-of-the-art differential encoding schemes to encrypt stored information. These encryption algorithms provide transmitting 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. RF semiconductor devices gain their internal energy from a surrounding ambient magnetic field making them self-contained, independent radio transmitters. The need for customer interaction such as to 'push-a-button' to begin a transmission or to change the battery has been eliminated. The combination of both technologies, cryptographic semiconductor and resonance magnetic RF communication in a single semiconductor device will be presented as the latest achievement in automotive electronics combining ultra high security with passive customer vehicle interaction including passive remote keyless entry, engine immoblizer, and passive identification tags.
