NFC tags (as defined by the NFC Forum) have no protection against cloning. Such tags are intended as containers for freely readable data (so called NDEF messages). NFC tags (as defined by the NFC Forum) have no protection against cloning. Such tags are intended as containers for freely readable data (so called NDEF messages). Anyone could read an NDEF message from one tag and duplicate it to another tag. While a standard NFC tag can be used to identify a product or item, there's nothing (generally) to prevent it from being duplicated into hundreds of counterfeit products. An authentication tag cannot be copied so each product has a substantially increased level of counterfeit protection. Using authentication in NFC tags isn't exactly new. Tags which do not make use of password-protection or over-the-air (OTA) encryption can have their data banks copied into new tags. RFID tags (at least Class 1 Generation 2 tags, aka UHF RFID tags) are computationally active, not passive.
There are two common ways to prevent tampering in NFC cards: locking and blocking. Locking involves one-time programmable (OTP) lock bits that make it impossible for unauthorised users to change the memory permanently.
Yes, many tag types permit write protection, some globally, and other more sophisticated ones by memory section inside the tag. When you get your tag detected in your Android NFC app, then you can get a Tag object and read and write to the tag, including protecting it from further writing. No authentication or protection mechanisms against reading of tag contents (or copying of tag contents to other tags) are standardized. However, some existing tag products implement additional security features that go beyond what is specified by the NFC Forum.
Again you want to encrypt using a key that includes the UID to prevent a plain copy of the data from working when copied to a new tag. Keep in mind, it doesn't matter what you do.
Smart tags are tiny, read-only chips that can appear in informational posters and identification documents, such as corporate badges or passports. You can even use NFC to connect to secure networks without having to enter complex authorization codes.
In this lesson, we will discuss how to enable memory protection for our NFC Pokemon tags. NFC tags (as defined by the NFC Forum) have no protection against cloning. Such tags are intended as containers for freely readable data (so called NDEF messages).
