Migrate to DESFire security

05.04.2018

MIFARE® DESFire, when secured with 128-bit encryption, is one of the most secure access control technologies in the world. DESFire achieves this using mutual authentication, which means both a reader’s and transponder’s security keys must match each other. This ensures a DESFire transponder can’t be cloned or even hacked, because only readers programmed with authentic credentials will trigger it to reply. Furthermore, DESFire encrypts transactions to make it impossible to skim credentials from the RF data stream between a reader and transponder.

DESFire ciphers, or security keys, are integral to DESFire. For example, all readers in a DESFire system must be programmed with particular security keys for reading certain transponder populations. Correspondingly, all transponders in a group must be coded to recognize those security keys. How to manage all of DESFire’s keys depends ultimately on an integrator’s, installer’s or end-users resources and priorities. Some choose to create and manage their keys independently (e.g., using Idesco DESCoder programming tool). Others prefer outsourcing some or all parts of their key management so they can focus on their core business or mission.
