  We present a Mutual Chip Authentication protocol for authentication and key agreement 
between mobile devices. It has been  designed as an option 
for  Terminal Authentication (TA) and Chip Authentication (ChA) 
developed for electronic travel documents (MRTD). 

Unlike conventional TA, the protocol execution does not provide any
digital record that could be used as a proof
against third parties that an interaction with a given terminal took place. 

Our design is symmetric in the sense that the code executed by both participants 
is the same (apart from the sequence of operations executed), which makes 
implementation easy on resource limited devices such as smart cards. So easily
each  participant can play the role of a card or of a terminal 
from conventional  TA.
