A system and method for the management of electronic credentials stored on mobile devices. The system may encrypt information that is provided to a lock device and an access control system using diversification keys. The diversification keys may be generated by supplying a master key and a component identifier such as, for example, a mobile device identifier, to a diversification algorithm. The mobile device may be a conduit for the communication of information between the access control system and the lock device. The mobile device may be unable to decrypt information that has been encrypted by a diversification key. Embodiments also provide for enrolling administrative mobile devices with the access control system, the distribution and revocation of credential identifiers for user mobile device, and removing administrative mobile devices that are enrolled with lock devices.

Electronic credential management system

A reader device may generate a first identifier. The reader device may transmit the first identifier to a mobile device. The reader device may receive encrypted data and unencrypted data from the mobile device in which the encrypted data includes a second identifier. The reader device may evaluate whether the first identifier and the second identifier correspond to one another.
