CONTACT-LESS TAG WITH SIGNATURE, AND APPLICATIONS THEREOF |
摘要 |
A method which comprises generating a first signature by encoding an identifier with a first additional data set at a first time instant; responding to a first read request from a tag reader by releasing the first signature; generating a second signature by encoding the identifier with a second additional data set at a second time instant, the second additional data set being different from the first additional data set; and responding to a second read request by releasing the second signature. Also, a method which comprises obtaining a signature from a contactlessly readable tag; decrypting the signature with a key to obtain a candidate identifier and a scrambling code associated with the signature; and validating the candidate identifier based on at least one of the scrambling code and the signature. |
