Datakey CryptoAuthentication memory tokens are a versatile tool for securely transporting data, unlocking devices, enabling features, storing log data, and more. The built-in Microchip ATECC608B1 and ATSHA204A CryptoAuthentication ICs enable stored data to be authenticated, protected, and encrypted, providing a high level of security. Data is stored in slots ranging from 32 to 416 bytes, depending on which CryptoAuthentication IC is used. An especially important feature is the ability for the host to authenticate the memory token, this prevents unauthorised devices from connecting and spoofing a memory token. The memory tokens also have a propriety form factor making it even harder to physically spoof a memory token. Depending on how the memory token is used in a particular application, these use cases, or parts thereof, can be combined. For example, the token may be used to securely track and limit the number of times a device can be used, while at the same time the token can securely log other data.
