Configurable Reader Applications Based on DESFire Technology

Idesco Oy : 12 July, 2010  (New Product)
Mifare's DESfire technology features on the range of card readers available from Idesco providing a combination of application flexibility and security
Many of Idesco's readers are configurable with either triple DES or AES encryption in combination with MIFARE's DESFire identification cards. This combination is an excellent choice when you need both configurable modern multi-applications and security. The key to the solution is the novel and powerful DESFire technology.

For starters, MIFARE's DESFire technology is designed to host multiple applications. Additionally, it provides you with significant flexibility in how you configure those applications. This flexibility includes the freedom to configure independent authentication keys even down to choosing different file locations for assembling a data string response to a reader's query. With DESFire, you can choose up to seven distinct authentication keys for the various applications your cards will host.

Most importantly, the DESFire transponder can provide the highest levels of encryption, Triple DES or even AES, for your response. Triple DES (Data Encryption Standard) employs a triple pass of the TDEA cipher, providing very robust protection against brute force attacks. For ensuring the utmost security, however, AES (Advanced Encryption Standard) carries 128-bit block and 128 bit keys; it is the first publicly accessible and open cipher approved by the NSA for top-secret information.

Most Idesco Access readers (8,9), Idesco Compact Modules, the Cardea Reader and Access Touch are easily configured with MIFARE's DESFire technology. If you already own readers configured with older MIFARE Classic technology, you can readily upgrade these units with DESFire transponders.
