Abstract: 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.

Abstract: An insulin pump is configurable by a configurator. The pump has parameter blocks, each with a respective parameter and an associated restriction setting, and the configurator has an authorization level. Configuring the pump includes receiving, by the configurator, a request to access a parameter on the pump. The method also includes identifying, by the configurator, the parameter block that includes the parameter. Moreover, the method includes retrieving, by the configurator from the pump, the parameter and the associated restriction setting, and comparing, by the configurator, the authorization level of the configurator to the restriction setting. Also, the method includes determining, by the configurator, whether the configurator is authorized to write to the parameter block based on the comparison. Additionally, the method includes writing, by the configurator, to the parameter block on the insulin pump in response to a determination that the configurator is authorized to write to the parameter block.
