CryptoAuthentication-Intro-Slide8

Many system architectures involve multiple elements. For a mobile device, there might be a replaceable battery, a charging station, special interface cables and more. For a medical system, there might be a consumable patient component, chemical bottles or spare parts. Each piece of these ecosystems must be authentic for the user experience or functionality to match that intended by the OEM. Some solutions require different software or devices to authenticate each element, but CryptoAuthentication, due to its flexibility, is the first chip that can be used in each of these situations. This parallel use means less time is required for understanding and developing the security procedures and fewer components on the bill of materials list. Crypto algorithms are often computationally slow, so adding an external chip with a hardware crypto accelerator means that the system firmware can continue with other processing while the authentication, key exchange or response validation takes place. Size and power consumption are key factors for many new systems. CryptoAuthentication automatically enters an ultra-low power sleep mode whenever it’s idle, preventing unnecessary battery drain. The very low operating voltage means that even at the end of battery life the chip still works just fine. With a selection of 3 and 8 lead packages, the CryptoAuthentication chip can fit in any system with ease.
