Restrictions This certificate only applies on the product specified in chapter 1.2 of this certification report. The user of the certified product shall respect the operational environmental security objectives specified in the security target [ST] and shall respect the recommendations in the guidance [GUIDES], in particular: - The issuing State or Organization must ensure that the Personalization Agents acting on the behalf of the issuing State or Organization: o Establish the correct identity of the holder and create biographic data for the MRTD; o Enrol the biometric reference data of the MRTD holder i.e. the portrait, the encoded finger image(s) and/or the encoded iris image(s); o Personalize the MRTD for the holder together with the defined physical and logical security measures (including the digital signature in the Document Security Object). The Personalization Agents enable or disable the Basic Access Control function of the TOE according to the decision of the issuing State or Organization. If the Basic Access Control function is enabled the Personalization Agents generate the Document Basic Access Keys and store them in the MRTD’s chip; - The Issuing State or Organization must: o Generate a cryptographic secure Country Signing Key Pair; o Ensure the secrecy of the Country Signing Private Key and sign Document Signer Certificates in a secure operational environment; o Distribute the Certificate of the Country Signing Public Key to receiving States and organizations maintaining its authenticity and integrity; The Issuing State or organization must: o Generate a cryptographic secure Document Signing Key Pair and ensure the secrecy of the Document Signer Private Keys; o Sign Document Security Objects of genuine MRTD in a secure operational environment only; o Distribute the Certificate of the Document Signing Public Key to receiving States and organizations. The digital signature in the Document Security Certification report 2006/28 AXSEAL CC V2 72K e-Passport application embedded on Philips P5CD072 V0Q microcontroller Page 12 out 17 CER/F/07.5 Object includes all data in the data groups DG1 to DG16 if stored in the LDS according to [ICAO]; - The issuing State or Organization has to establish the necessary public key infrastructure in order to: o Generate the MRTD’s Active Authentication Key Pair, o Sign and store the Active Authentication Public Key in the Active Authentication Public Key data in EF.DG15, o Support inspection systems of receiving States or organizations to verify the authenticity of the MRTD’s chip used for genuine MRTD by certification of the Active Authentication Public Key by means of the Document Security Object; - The issuing State or Organization must ensure that the MRTD administrator acting on the behalf of the issuing State or Organization establish the correct identity of the holder and update the MRTD with the defined physical and logical security measures. According to the decision of the issuing State or Organization the MRTD administrator can for example terminate the application or execute any administrative commands provided by the TOE; - The inspection system of the Receiving State must examine the MRTD presented by the traveller to verify its authenticity by means of the physical security measures and to detect any manipulation of the physical MRTD. Additionally the Extended Inspection System performs the Active Authentication mechanism to verify the Authenticity of the presented MRTD’s chip; - The border control officer of the Receiving State uses the inspection system to verify the traveller as MRTD holder. The inspection systems must have successfully verified the signature of Document Security Objects and the integrity data elements of the logical MRTD before they are used. The receiving States and organizations must manage the Country Signing Public Key and the Document Signing Public Key maintaining their authenticity and availability in all inspection systems; - The inspection system of the receiving State ensures the confidentiality and integrity of the data read from the logical MRTD. The receiving State examining the logical MRTD being under Basic Access Control will use inspection systems, which implement the terminal part of the Basic Access Control and use the secure messaging with fresh generated keys for the protection of the transmitted data (i.e. Basic Inspection Systems). The receiving State examining the logical MRTD with Primary Inspection Systems will prevent eavesdropping to the communication between TOE and inspection system; - The holder may prevent attempts to disclose the logical MRTD by following recommendations for the protection of the MRZ against unauthorized people. An attacker knowing the MRZ or a part of it have better chance to perform a successful skimming or eavesdropping attack. 3.3. Recognition of the certificate 3.3.1.
