Abstract
The exemplary embodiments may provide a secure framework for devices in a drug delivery system to wirelessly communicate. The secure framework may use encrypted keys to carry credentials and to specify the rights of the devices presenting the credentials. The devices in the drug delivery system present the keys at the time that they wish to wirelessly communicate with other devices in the drug delivery system. The devices receiving such keys, decrypt the keys and verify if the credentials are valid. If the credentials are valid, a wireless communication session between devices may be established.

1-20. (canceled)
A glucose monitor, comprising:
- a wireless transceiver for transmitting and receiving wireless communications;
- and
- a processor configured to:
- receive a secure package via a wireless communication from a device when the glucose monitor is uninitialized,
- extract contents of the secure package, including an initialization code and
- a key,
- validate the key as valid or not,
- where the key is valid,
- permitting the device to conduct wireless communications with the
- validate the initialization code as valid or not,
- where the initialization code is valid, initialize the glucose monitor,
- where the initialization code is not valid, not initialize the glucose monitor, and
- where the key is not valid, not permitting the device to conduct wireless communications with the glucose monitor.
A wearable device, comprising:
- a wireless transceiver for transmitting and receiving wireless communications;
- and
- a processor configured to:
- compose a secure package that includes a key and an initialization code,
- transmit the secure package to a glucose monitor that is uninitialized to initialize the glucose monitor,
- where the key is valid and the initialization code is valid, receiving an indication from the glucose monitor that the key is valid and the initialization code is valid, and
- otherwise receiving an indication that attempt to wirelessly communicate with the glucose monitor and initialize the glucose monitor has failed.
A medicament delivery device, comprising:
- a wireless transceiver for transmitting and receiving wireless communications;
- and
- a processor configured to:
- receive a secure package from a requesting device,
- extract contents of the secure package, including a key and an indication of rights of the requesting device,
- validate the key as valid or not,
- where the key is valid, in view of contents of the secure package, grant only viewing rights to the requesting device so that the requesting device can read information from the medicament delivery device but is prohibited from changing values stored at the medicament delivery device and from issuing commands to the medicament delivery device;
- and
- where the key is not valid, not permit wireless communications between the medicament delivery device and the requesting device.
