Can Maxim certify that a DS1961S is not duplicable?

Question

Accepted Answer

​​ ​ ​ ​ No 1-wire part is duplicable since each one has a 64 bit guaranteed UNIQUE ID. 
 ​ In addition, the DS1961S is a SHA-1 based iButton which means the authentication method does not rely only on the 64 bit ID but also on a computed MAC that uses the 64 bit ID and other data (random number for each transaction, page data and secret key that is in a write only register).
