摘要: Electronic passports (ePassports) have known a wide and fast deployment all around the world since International Civil Aviation Organization published their specifications in 2004. Based on an integrated circuit, ePassports are significantly more secure than predecessors. Forging ePassport is definitely thwarted by use of cryptographic means. In spite undeniable benefit, raised questions about personal data protection, attacks basic access control mechanism came into sight. Keys used for that purpose derive from nothing but predictable machine readable zone data, so suffer weak entropy. We provide in-depth evaluation key entropy, prove Belgian passport, recipient Interpol "World's most passport" award 2003, provides worst entropy one has ever seen. also state two-thirds circulation do not implement any protection mechanism. demonstrate our claims means practical attacks. then recommendations to amend security, directions further work.
