Abstract
Methods and systems for implementing one-time pad (OTP) encryption in industrial wireless instruments advantageously make use of data storage devices now available that can store a large number of encryption keys or pads in a small enough package to fit within an industrial wireless instrument. In some embodiments, the wireless instruments use solid-state memory devices that can easily hold a sufficient number of pads to last the expected lifetime of the wireless instruments. The solid-state memory devices are installed only during manufacturing of the wireless instruments where tamper-resistant manufacturing and assembly techniques may be used to ensure security for the pads. Likewise, the solid-state memory devices of the wireless instruments are also replaced or replenished only at an authorized manufacturer should additional pads be needed.
