System for programming a lock comprising contactless NFC communication means

摘要

The invention relates to a system including a lock (10) provided with electronic NFC transceiver circuits and electric circuits for controlling mechanical locking/unlocking members, and a portable telephone (16) provided with circuits for NFC mode of operation. The telephone comprises means for initializing the lock, said means including means for: downloading, from a remote site (20), an applet and elements required for initializing the lock; verifying, using the telephone, the identifier and the transport key stored in the lock against the downloaded ones; deactivating the transport key of the lock; loading, onto the lock, a unique random algorithm and a cryptographic key that have been downloaded; and generating a message notifying of the termination of the initialization of the lock.

主权项

1. An access control system comprising:
a lock comprising electronic circuits that enable the lock to engage in contactless communications, the lock further comprising electric circuits that enable the lock to control one or more mechanical elements; a portable communication device comprising circuits that enable the portable communication device to engage in the contactless communications with the lock; and a lock-programming application that enables the portable communication device to program the lock via the contactless communications with programming elements that include, wherein the lock-programming application is configured to:
receive a lock identifier and a transport key used to secure the lock during transport thereof;confirm validity of the received lock identifier by comparing the lock identifier with an authorized lock identifier;confirm validity of the received transport key by comparing the received transport key with an authorized transport key; andupload the programming elements to the lock thereby deactivating and replacing the transport key.
