Estimating the term…
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.
A method for managing verification keys for a plurality of RFID readers in an authenticated RFID system comprising determining a set of permissions indicative of which of one or more of said plurality of RFID readers have permission to authenticate one or more product types;
A computer readable medium carrying computer executable instructions for managing verification keys for a plurality of RFID readers in an authenticated RFID system by:
A key management system for an authenticated RFID system having a plurality of RFID readers configured for determining a set of permissions indicative of which of one or more of said plurality of RFID readers has permission to read one or more product types having corresponding RFID tags;
