Abstract: A method includes performing, by a terminal with an access card, a first relay attack check for the access card in accordance with a local value associated with the terminal and a local value associated with the access card; determining, by the terminal, that the access card has passed the first relay attack check, and based thereon, performing, by the terminal with the access card, an authentication check of the access card in accordance with the local value associated with the terminal, the local value associated with the access card, and a local challenge value associated with the terminal; and determining, by the terminal, that the access card has passed the first relay attack check and the authentication check, and based thereon, validating, by the terminal, the access card.

Abstract: A tamper resistant device can be used for an integrated circuit card. The device includes memory storing a first security domain that includes a telecommunication profile and a second security domain that includes an application profile. A first physical interface is configured to be coupled to a baseband processor configured to operate with a mobile telecommunications network. A second physical interface configured to be coupled to an application processor. The first physical interface configured to allow the baseband processor to access the telecommunication profile and the second physical interface is configured to allow the application processor to access the application profile. The tamper resistant device is configured to enable accessibility to the application profile if corresponding commands are received at the first interface and to enable accessibility to the telecommunication profile if corresponding commands are received at the second interface.
