TruST25 digital signature from Factory to Consumer

How can I reliably authenticate my products ?
RFID/NFC tags have long been used to improve the efficiency of global supply chains. Additionaly, NFC/RFID tags with an embedded digital signature eliminate the risk of counterfeit and gray market goods. Thanks to this cryptographic solution and a secure manufacturing environment, it is now possible to guarantee the integrity of products and authenticate their origin.
