1. A method for pairing a diabetes managing device with an insulin pump for secure wireless communication, comprising:
- preloading an encryption key into a first memory of the diabetes managing device during manufacture of the diabetes managing device;
preloading the encryption key into a second memory of the insulin pump during manufacture of the insulin pump;
at the diabetes managing device, generating a first verification string from the encryption key;
at the insulin pump, generating a second verification string from the encryption key;
at the diabetes managing device, displaying the first verification string on a display of the diabetes managing device;
at the insulin pump, displaying the second verification string on a display of the insulin pump;
at the diabetes managing device, receiving a first confirmation input in response to the first verification string being displayed, the first confirmation input indicating that first verification string matches the second verification string;
at the insulin pump, receiving a second confirmation input in response to the second verification string being displayed, the second confirmation input indicating that the first verification string matches the second verification string; and
establishing a secure bidirectional communication link between the diabetes managing device and the insulin pump based on the receipt of either the first confirmation input by the diabetes managing device or the receipt of the second confirmation input by the insulin pump.
