While all Digi radios come with some built in features to enhance security, the XTend and the XBee product families have the capability for built-in AES encryption of data packets. Digi has received FIPS-197 certification on the AES algorithm for the XTend, making it easier to deploy the radios in government applications or those situations requiring a certified encryption algorithm. The encryption features for the XBee radios have recently been released and are currently available by downloading the latest firmware upgrade.
Updated AES Encryption
Several of the Digi radios have the ability to set and use encryption keys for data security. In some applications such as those sending financial information or other sensitive data, it is often desirable to protect the transmitted data from any sort of eavesdropping or data spoofing.
