Anti-hacker or cloner safe blood glucose meter implementation

Most glucometer implementations include consumables such as test strips or chemical reagents, and the key to the operation of such devices is to ensure that these test strips are all reliable products from OEMs and can read and group with specific test strips correctly. Related calibration information.

Atmel's CryptoMemory, CryptoRF, and CryptoAuthentication devices use high-security design technology that combines non-volatile memory and hardware encryption engines for storing keys, providing a robust turnkey solution to these two challenges. Program.

Many medical environments may encounter environmental problems caused by water, various contaminants, and disinfecting chemicals. Under these circumstances, users can use contactless RFID tag solutions to achieve robust operation. Atmel offers a complete RFID solution, including the smallest reader, and a range of tags of different sizes.

These chips are specifically designed to be integrated into these devices to prevent hackers or cloners from replicating meters or providing poor quality supplies.

Counterfeit products not only steal the profits of OEM manufacturers, but also cause users security threats if the blood glucose meter reads incorrectly. When any unfortunate incident occurs because of incorrect meter readings, the supply chain must also bear the risk of liability. In short, these all prove that using a more robust authentication method than bar codes or holograms is appropriate.

To increase market share, OEMs must provide tester users with low-cost consumables, and the additional cost of adding a certified chip must also be minimized. Atmel's certification solutions are designed from the very beginning to meet this need. For example, a single encryption engine optimized for cost can be used. Since the frequency of certification operations is low, high-performance devices are not required.

There is no other supplier like Atmel that offers a wide selection of EEPROM memory density for security chips. If the design only needs to store a small number of keys or authentication secrets, you can use 512-byte models; if the product model information, calibration measurement parameters, or the storage of test results requires more space, Atmel is available with a density of up to 32KB. And all products have the same high level of hardware security.

Atmel provides a complete software library to implement host-side authentication and encryption protocols, and is the only vendor that offers a full range of compatible turnkey host chips that can increase overall system security while simplifying design.

All Atmel's encryption devices can be personalized in two ways: 1) Each customer is programmed for each application and a unique set of secrets is added to the device. Each cryptographic chip has up to 16 different keys, giving designers a number of possible ways to partition different categories of confidential information. 2) There are many different ways to configure authentication and data protection in the chip. For example, only a doctor in one area can write data; another area may only store manufacturing history information and so on.

Because these chips are all turn-key hardware devices, eliminating the need for a microprocessor, designers do not need to program, can speed time-to-market, and reduce test and verification costs.

This analysis system can be implemented using a variety of different microcontrollers and use a single-wire or two-wire interface to connect these encryption chips. These microcontrollers are available in small 8-pin or even smaller 3-pin packages, allowing them to accommodate the most compact handheld device configurations.
