SAM and security



The security of a contactless system is based on secret keys that authenticate transactions between the terminals and the cards.

These keys are stored into the cards or ticket and into a Secure Application Module (SAM). A SAM is a smartcard installed permanently in the equipment interacting with the cards or tickets.

ASK provides a comprehensive service for the ticketing systems projects of transport authorities by:

  • Defining the security architecture in accordance with interoperability and specific application requirements.
  • Organizing and executing the keys generation ceremony
  • Storing securely the master secret keys
  • Ensuring the permanent confidentiality of the keys

SAMs contain cryptographic keys that are being generated during ASK’s key ceremonies and personalized to the terminal function (production, emission, loading or validation…). ASK is also the pioneer of SAM issuing in Calypso world and other implementations.
