Memory devices, like Datakey CryptoAuthentication memory tokens, are used to validate a user or device and securely transfer information to an embedded system. Learn about symmetric authentication and terms like challenge, nonce, digest and more.

It’s game time, and your design calls for a portable memory device. Customize your memory device at Datakey.com and select: Memory Technology, Capacity, Serial Interface, Form Factor, Color, Logo and Customization Options.

Designed for use as a credential for small, hand-held embedded applications, Mini-Bar memory tokens are a little larger than a microSD card but are thicker, stronger, and easier to handle. Memory options include SPI or I2C EEPROM in 16 or 256 Kbits.

When security or reliability concerns preclude the use of USB flash drives or SD cards, RUGGEDrive memory tokens offer a more secure and robust solution.  Eliminate USB ports or SD card slots, so uncontrolled flash drives and SD cards won’t plug in.

Incorporating a secure memory device into an embedded design doesn’t have to be hard. Learn how to integrate a Datakey CryptoAuthentication memory token. View product info, white paper, application note, learning lab video and more.

Datakey is the recognized leader in Crypto Ignition Keys (CIKs). CIKs are essential in many security applications and serve as a primary way to restrict access and de-classify equipment. This paper explains how to implement a removable memory device as a CIK.

This paper explains wireless coexistence and shows four ways to link/pair two or more devices to prevent unintentional crosstalk. Using a portable memory device to transfer device ID information between transmitter and receiver is examined in detail.
