Abstract: A security token is provided having a communication interface with a communication transceiver; a circuit having encoded thereon an immutable hardware key; and a tangible, nonvolatile memory, the nonvolatile memory having stored thereon a mutable software key, the mutable software key including a cryptographic key and an expiry for the cryptographic key.

Abstract: In some examples, a dialysis system is configured to track consumables used by a dialysis machine to deliver a dialysis treatment to a patient in order to facilitate the delivery of additional consumables for use in future dialysis treatments. The dialysis machine can be configured to use a cartridge to replenish a dialysate and/or a recharger configured to recharge the cartridge. The dialysis system may track a consumables inventory (e.g., stored locally with the patient, such as at the patient's home) based on an amount of dialysate provided to a dialyzer over the course of the dialysis treatment and a dialysate prescription of the patient. The dialysis system may communicate the consumables inventory and/or a consumption of consumables associated with the patient to a remote device. The remote device may schedule a delivery of consumables to the patient based the consumables inventory and/or the consumption of consumables.

Abstract: A medical system includes a medical device with processing circuitry configured to receive sensor data and send the sensor data to a diagnostic system. The sensor data includes sound data associated with blood flow and vibration data associated with blood flow. The diagnostic system includes a computing system configured to receive the sensor data and output devices. The output devices include a speaker configured to output a sound based on the sound data and a haptic device configured to provide a haptic feedback based on the vibration data.

Abstract: Systems and methods for performing mutual authentication between a hardware access token and a reader device are provided. The systems and methods include reading a unique or pseudo-unique identifier of the hardware access token and computing a password for the hardware access token based on the unique or pseudo-unique identifier and a group secret of the reader device.

Abstract: A security token is provided having a communication interface with a communication transceiver; a circuit having encoded thereon an immutable hardware key; and a tangible, nonvolatile memory, the nonvolatile memory having stored thereon a mutable software key, the mutable software key including a cryptographic key and an expiry for the cryptographic key.

Abstract: The disclosure relates to systems, devices, and methods for authenticating users of any device requiring authentication, such as a medical device. The systems, devices, and methods can convert a standard USB mass storage device into a unique USB based authentication device that authenticates a user. The device can be programmed to grant access to one or more functions only upon verification of a user by inserting the USB based authentication device into the medical device.

Abstract: The invention relates to devices, systems, and methods for controlling smart card authentication for a system. The systems and methods can include a smart card reader for gaining access to a smart card by sending a first password to access the smart card wherein the smart card reader can read a unique ID of the smart card and use an algorithm to generate a second password and store the generated second password directly in the smart card's file directory. The medical systems can include any medical device or machine requiring the transfer of any data such as personal health information (PHI) and therapy parameter data to be used by medical devices in the system. The methods, algorithms, and processes can also be used as a standard for any number of devices and systems for accessing a particular device.
