An example field device includes a Bluetooth Low Energy (BLE) interface to receive a first initialization message from a remote device over an unpaired BLE connection. The first initialization message includes a plaintext message containing authentication content. The authentication content is generated based on a private authentication token available to the remote device using middleware. The field device also includes a BLE message analyzer to validate the plaintext message based on the authentication content using the authentication token stored by the field device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus to establish secure low energy wireless communications in a process control system","description":"Methods and apparatus to establish secure low energy wireless communications in a process control system are disclosed.
