General description

The ICODE DNA is a leading-edge HF tag IC targeting brand protection tagging

applications which require HF long read range as well as cryptographic authentication

check.The security is based in the first place on a 128-bit AES key which is securely

stored on IC’s and which is used to perform cryptographic authentication by an AES

coprocessor. The current version of the ICODE DNA supports the following features:

• Tag and mutual authentication using AES128

• 3 user keys for tag authentication and/or mutual authentication

• Separate privileges to define different access rights per key

• Flexible user memory segmentation with corresponding access conditions

• 2016-bit available user memory

• NXP originality signature

• Counter feature
