Abstract
Disclosed are apparatus and methodology for providing secure control over stored metrology parameters. A random number key is generated and associated with identifiable information such as a serial number associated with a device. The random number and identification information are stored in a database separate and remote from the device. Alteration of the stored metrology parameters are permitted only upon use of the random number as a key to unlock the device.
Claims20
A method for securing an endpoint, comprising:
- generating a random number key;
- associating the key with an identifiable endpoint;
- and
- storing the key and endpoint identification information in a database.
A method for securing stored parameters, comprising:
- generating a random number key;
- associating the key with an identifiable device;
- storing the key and device identification information in a database remote from the device;
- and
- permitting alterations of the parameters only with possession of the key.
A metrology system, comprising:
- a meter configured to generate signals indicative of measured quantities;
- and
- an endpoint, said endpoint comprising a controller, a memory, and a communications module,
- wherein said controller is configured to receive said signals, said memory stores meter measurement parameters related to said signals, and said endpoint is configured to require possession of an associated random number to alter the stored meter measurement parameters.
A method for enhancing measurement reliability, comprising:
- generating a random number key;
- associating the key with an identifiable measurement device;
- storing the key and device identification information in a database remote from the measurement device;
- associating measurement parameters with the measurement device;
- and
- permitting alterations of the measurement parameters only with possession of the key.
