ePassport Protocol on the Spi Calculus

Electronic passport promises the possibility of a secure, simple and quick travel formalities. Many countries have started delivering electronic documents to their citizens. This is a proof of the importance of ePassport protocols which aim to improve the document security and the traveller authentication. Three generations of security solutions in ePassports were speci ed. We model via this work a new protocol of ePassport to provide better authentication and to protect sensitive data. Elliptic curve cryptography and secret sharing scheme present the main topics referred to in the proposed protocol. This coupling strengthens the eMRTD security, data storage and the authentication of both ePassport and its bearer. The Spi calculus is an adequate formalism to model cryptographic aspect of such electronic protocol and allows us to verify its properties.
