Hi,
in our design we would like to replace a smartcard by a kind of security chip or security module. The chip has to provide:
- unique ID / serial number
- secure key management
The idea is to store data on the device in a way that they cannot be read (hence encryption) or copied to a similar device (hence unique ID) without the particular security chip being involved. The actual data are some kB only, so if there is internal persistent memory on the security chip it cold be utilized, but it is not a requirement. External flash memory or EEPROM is sufficient. The memory does not need to be controlled by the security chip, since on the device there is a powerful microcontroller that can control the chip and the memory as well.
So far I did not find any useful information what chip could be used for this.
Any ideas or hints?
TIA, Matthias
