Abstract:
1. A method for security authentication of radio frequency identification, comprising: a security authentication control apparatus sending an inventory command to a tag via a reader, said tag feeding back an Electronic Product Code (EPC) to said security authentication control apparatus via said reader; said security authentication control apparatus randomly generating an unencrypted random number and sending said unencrypted random number to said tag via said reader; said tag directly using a locally stored encryption key to carry out an encryption calculation directly on said unencrypted random number randomly generated by and received from said security authentication control apparatus to generate encrypted data, and feeding back said encrypted data to said security authentication control apparatus via said reader; and said security authentication control apparatus carrying out the security authentication on said encrypted data; wherein, the inventory command sent by said security authentication control apparatus via said reader is an inventory command with a mask code; said tag obtains the mask code from said inventory command with the mask code and performs matching on a locally stored EPC code, if matching successfully, returns a matched EPC code to said security authentication control apparatus via said reader; and wherein said security authentication control apparatus authorizes the EPC code fed back by said tag to be used by an upper layer application after said security authentication control apparatus carries out the security authentication on said encrypted data successfully.
