CNA security Work Package

Calypso technology has built its reputation on a proven security
architecture enabling authentication of all transactions between a
Portable Object and a terminal.

The Calypso core security system has now evolved for over 15 years
without any known forgery or notorious security problems, but, since
security is always a matter of anticipating possible threats and
attacks, CNA has a permanent security working group  to define the  Calypso
security architecture for the incoming years.
