Abstract

Millions of citizens around the world have already acquired their new electronic passport. The e-passport is equipped with contactless communication capability, as well as with a smart card processor enabling cryptographic functionality. Countries are required to build a Public Key Infrastructure to support digital signatures, as this is considered the basic tool to prove the authenticity and integrity of the Machine Readable Travel Documents. The first large-scale world wide PKI is currently under construction, by means of bilateral trust relationships between Countries. In this paper, we investigate the good practices, which are essential for the establishment of a global identification scheme based on e-passports, together with the security and privacy issues that may arise. We argue that an e-passport may also be exploited in other applications as a globally interoperable PKI-enabled tamperproof device. The preconditions, the benefits, and the drawbacks of using e-passports in everyday electronic activities are further analyzed and assessed.
