A system for bidirectional device authentication between two computing devices is disclosed. A first processor generates a first random number sequence, performs a first operation on the first random number sequence to determine a first table address, and retrieves a first entry in the first table based on the first table address. The processor also executes a first transformation function on the first entry to generate a first transformed entry, transmits the first random number sequence to the second computing device, receives an encoded entry from a second computing device in response to transmission of the first random number sequence, and decodes the encoded entry to determine a second transformed entry. The first transformed entry matches the second transformed entry, and the first processor performs an update to a dynamic table by replacing each entry of the dynamic table with an associated transformed entry.

Apparatuses and methods thereof to administer and manage a base unit for a handheld medical device are disclosed. In one embodiment, a base unit of the invention is in communication with a handheld medical device. The base unit is configured to provide an electrical connection to a power source to charge a battery of the handheld medical device. The base unit is also configured to perform an update to the operation of the base unit, wherein the update is initiated by the base unit upon receiving from the handheld medical device a data stream with information indicating that an update is contained in the data stream.

A handheld diabetes management device having a database management system is disclosed. The device comprises a plurality of input modules, including a blood glucose reader, a user interface, a communications interface, and a continuous blood glucose input module. The input modules output data used to generate data records of different record types. The device further comprises N databases, each database having a different frequency range associated thereto, wherein the new record is stored in a particular database of the N databases based on the frequency range of the particular database and the frequency of the particular record type, and N is an integer greater than 1. The device further includes a database operation module that performs database operations on the N databases. The database management system provides increased reliability in the keeping of records on which medically important decisions are made.
