The T6ND4 Integrated Circuit (Target of Evaluation - TOE) is an Integrated Circuit (41 pin BGA package) with a DES accelerator. The TOE that is described in this ST is a single chip microcontroller (hardware, security IC dedicated software to initialise a number of settings for sensor levels and countermeasures at start-up and security IC dedicated test software) that is used in mobile equipment. The TOE combined with an IC for communication (which is not part of the TOE) realizes a platform for electric purse. The TOE has three different communication interfaces:
1. an interface, a wireless interface that receives modulation data from the IC for communication,
2. a mobile host interface, a wired serial interface that communicates with the host controller of the mobile equipment,
3. a RFChip interface, a local serial bus that monitors the IC for communication.
The objective of the TOE is to protect the IT security of the IC and embedded software that is intended to be used as an electronic purse (people can pay with the TOE embedded in mobile equipment).
