When a security company comes out and announces that its next-generation RFID ICs are unclonable, you can be sure that the company will attract a lot of attention, though the question is whether the attention is the desired type (potential customers), or the undesired type (folks who want to crack such security measures). The first chip of the new product family, boasting the company’s Physical Unclonable Functions (PUF) technology, will be the Vera M4H, which can deliver security to mass transit tickets, secure IDs, access cards and many other things. It sports a non-networked, unlimited authentication feature, which should help offer the security needed, with significant cost benefits. The M4H is currently available for mass production, while the other RFID ICs in the product family will be available later this year. Do you think that there is such a thing as an unclonable chip, or is it just a wishful boast?
