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?<span class="lia-inline-image-display-wrapper" image-alt="图片1.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/17271i5A260CEB5AA50DB3/image-size/large?v=v2&amp;px=999" role="button" title="图片1.png" alt="图片1.png" /></span></P><P>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?</P><P></P><P>Thanks</P></BODY></HTML> Fri, 11 May 2018 09:25:56 GMT https://community.nxp.com/t5/NFC/Cryptographic-authentication-between-HTRC110-Hitags256/m-p/746215#M3204 liaojun 2018-05-11T09:25:56Z Re: Cryptographic authentication between HTRC110 & Hitags256 https://community.nxp.com/t5/NFC/Cryptographic-authentication-between-HTRC110-Hitags256/m-p/746216#M3205 <HTML><HEAD></HEAD><BODY><P>I send the information in your internal case</P><P>BR</P><P>Jonathan</P></BODY></HTML> Fri, 01 Jun 2018 16:58:30 GMT https://community.nxp.com/t5/NFC/Cryptographic-authentication-between-HTRC110-Hitags256/m-p/746216#M3205 Jonathan_Iglesias 2018-06-01T16:58:30Z Re: Cryptographic authentication between HTRC110 & Hitags256 https://community.nxp.com/t5/NFC/Cryptographic-authentication-between-HTRC110-Hitags256/m-p/746217#M3206 <HTML><HEAD></HEAD><BODY><P>Thank you for your reply.</P><P></P><P></P><P></P><P>liaojun@asionsys.com.cn</P></BODY></HTML> Wed, 06 Jun 2018 06:17:00 GMT https://community.nxp.com/t5/NFC/Cryptographic-authentication-between-HTRC110-Hitags256/m-p/746217#M3206 liaojun 2018-06-06T06:17:00Z
