Hi All,
I have several questions about the HTRC110 and hitags256 tags. How is the 32 Bit Secret Data used in the authentication between the two generated? Does the HTRC110 chip automatically perform calculations or other methods? What does the security co-processor mean?

Is the password for the second and third pages of the hitags256 tag written to itself? Then these passwords participate in the certification of tags and readers?
