Tracking Use Case

This simple Use Case illustrates the benefits of using the strong security of a Renesas Security Chip vs. a traditional non-secure technology (EEPROM). It illustrates many of the key fundamentals of strong security for authentication applications. The other Use Cases build upon the information presented here

In this application, a person must verify that the device in question is an authorized one and perform an enforcement function; i.e., prohibit a connection or remove an unauthorized device. A basic, non-secure method of identifying a device is to put a tag or an embossed or printed ID on it containing its serial number. Tags can be altered or replaced, so they offer little security. Embossed IDs can't be removed and can be difficult to alter, though, so they do provide a good level of security against ID tampering. However, they typically are not used on motherboards. Putting the ID into an EEPROM on the motherboard to provide this serial number to software running on the system might be adequate in some situations, but it is not feasible in large volumes.
