摘要：
A system for securely storing data, such as an odometer value in a vehicle, includes a non-transitory computer readable medium to store instructions of the system and a processor configured to execute the instructions. The processor is configured to use a master key to update a key and use a first key to store a value. The processor is further configured to use a second key for hiding the data and use a third key for securing the data.
