With CryptoAuthentication there are many benefits that will enhance and improve overall system security and, ultimately, help ensure end user satisfaction. In a product or system with one or more accessories, knowing that these accessories are designed to work with the system will help maximize overall system performance. Knowing that the controller with the additional feature was designed to work with the game system, for example, lets the system take full advantage of the controller and deliver the best overall experience to the user. That positive experience helps build brand loyalty and maximize revenue for the game system and controller OEMs. The same applies to replacement or spare parts--knowing they are of the same quality as the originals maintain that positive user experience. Whether a small product or large system, integrating a hardware security device like CryptoAuthentication into the design can prevent overbuilding by contract manufacturers or cloning by competitors. As an integrated component to product operation, such a security device and the information it protects are required for proper operation. Using state-of-the-art techniques, CryptoAuthentication ensures that the information it protects cannot be duplicated, nor can the product in which it is integrated. When it comes to making warranty repairs, this same feature can be used to ensure that only OEM devices are considered for repair. Today, many products are connected to the Internet directly and receive software updates through this channel. Even if updates are done manually using a USB memory device, it’s important to ensure that only authorized updates are made for continued proper operation of a product. CryptoAuthentication in a product design can also be used to authenticate encrypted updates and downloads.
