Abstract
A method and system for security authentication of radio frequency identification are disclosed. All the security control in this method is completed by the security authentication control apparatus. The reader is for the command transmission and the tag data forwarding, and there is not the security authentication control logic, the security authentication and the non security authentication can be supported at the same time. The key in the tag is unreadable, which ensures that the tag is unable to be replicated; the constant for every security authentication is randomly generated by the control module, and is returned by the tag after being encrypted, which presents the air interface from intercepting the useful information. This method provides the inventory with the mask code before the security authentication, which can have a certain filtering function on the tag data. The mask code can be configured flexibly.
