  • Radio frequency identification transponder security
    Patent number: 8035489
    Abstract: Security and privacy of tag information in an RFID-based system can be achieved through the usage of pseudonyms generated based on one-way hash functions. A system based on binary one-way trees allows for the scalable generation and decoding of authentication keys to obtain access to tag identities. The apparatus and methods described can also be adapted to provide limited access for readers to tag information.
    Type: Grant
    Filed: January 11, 2006
    Date of Patent: October 11, 2011
    Assignee: British Telecommunications public limited company
    Inventors: Trevor Burbridge, Andrea Soperra
