Chip card controllers for improved security

28 July 2004 DSP, Micros & Memory

Infineon Technologies has developed new chip card controllers for improved security of electronic identity cards and passports. Infineon's SLE66CLX640P security controller is designed for future chip card-format electronic ID cards, while the SLE66CLX641P controller is intended for integration into electronic passports. The security controllers contain more than 50 individual security mechanisms built into the chip. Featuring a storage capacity of 64 kilobytes, they belong to Infineon's 66Plus family of 16-bit chip card controllers. There are also numerous physical protection functions, such as an active shield feature and encryption functionality. The Memory Management Unit of the chips contains hardware firewalls, in order to keep the applications and other system software securely and reliably separate from each other.
