MIFARE® DESFire® EV1 is an ISO14443A RFID transponder and an NFC Type 4A Tag Platform that is used in many NFC and RFID security applications due to the ability it has to operate in the clear or operate as a secure transponder using any one of three different types of encryption: Single DES, Triple DES, or AES. In general, AES is viewed as the most secure level of encryption of the methods listed above, and therefore TI has developed a software library for demonstrating the use of AES encryption in RFID applications. Using this library along with an MSP430G2553 LaunchPad™ Development Kit combined with a DLP-7970ABP BoosterPack™ Plug-in Module, TI can now provide a demonstration of a cost-effective reader system solution for AES authentication applications that use MIFARE DESFire EV1 tags. Common application examples are digital door locks, access control, closed- or open-loop authentication systems, and prepayment or micropayment systems.
