Abstract: A system and method for performing cryptographic functions in hardware using read-N keys comprising a cryptographic core, seed register, physically unclonable function (PUF), an error-correction core, a decryption register, and an encryption register. The PUF configured to receive a seed value as an input to generate a key as an output. The error-correction core configured to transmit the key to the cryptographic core. The encryption register and decryption register configured to receive the seed value and the output. The system, a PUF ROK, configured to generate keys that are used N times to perform cryptographic functions.

Abstract: The invention provides systems and methods that allow retail entities to let consumers register a product or warranty at the point of sale. More specifically, the systems and methods described herein allow a retailer to identify a point during a purchasing transaction wherein the consumer has completed a transaction. At that time, the retailer may presented to the consumer an interface that the consumer may easily complete to allow the consumer to participate in a product or warned she registration process. As such, the systems and methods described here and make the product registration process part of the purchase transaction and therefore make the product registration process seamless and more facile. Consequently it is understood that consumer participation within the product registration process increases.
