    摘要: Undesirable electronic messages, such as the unsolicited broadcast e-mail known as spam, is not only a nuisance, but wastes both computer and user resources. Conversely, desirable electronic messages with sensitive content is important to secure, so that it is not forged, tampered or revealed. Accordingly, the present invention provides cryptographic methods that simultaneously secures electronic communication and helps fight spam.

    摘要: An authenticated RFID system is provided that uses elliptic curve cryptography (ECC) to reduce the signature size and read/write times when compared to traditional public key implementations such as RSA. Either ECDSA or ECPVS can be used to reduce the signature size and ECPVS can be used to hide a portion of the RFID tag that contains sensitive product identifying information. As a result, smaller tags can be used or multiple signatures can be written at different stages in a manufacturing or supply chain. A key management system is used to distribute the verification keys and aggregate signature schemes are also provided for adding multiple signatures to the RFID tags, for example in a supply chain.

    摘要: A system and method for controlling a production process for producing a product is provided in which overproduction may be inhibited by introducing a separation of duties within a production process. Typically a producer will contract out the various stages of a production process to multiple contractors. In general, separation of duties involves purposefully separating production stages, for silicon chips or other products, so that the end product has been handled or “touched”, by each subcontractor, in order for the end product to be fully functional.
