Optimized for personal and object identification
Infineon's my-d™ products are available in plain mode with open memory access and in secure mode with memory access controlled by authentication procedures. Architectural interoperability of my-d™ products enables an easy migration from simple to more demanding applications.
Flexible controls within the my-d™ devices start with plain mode operation featuring individual page locking; for more complex applications various settings in secure mode can be set for multi user / multi application configurations. In plain mode access to the memory is supported by 4-byte block as well as 8-byte page structure. In secure mode a cryptographic algorithm based on a 64-bit key is available. Mutual authentication, message authentication codes (MAC) and customized access conditions protect the memory against unauthorized access. Configurable Value Counters featuring anti-tearing functionality are suitable for value token applications, such as limited use transportation tickets.
