ABSTRACT:
A wireless lock and key system using an encryption key pair. When a lock senses a person nearby, the random signal is generated. The key encrypts the signal and returns it to the lock. The lock decrypts the signal and compares it to the original to determine if the lock should be opened. The key may generate temporary tickets for guests to open the lock for limited times.
