Disclosed are a digital door lock, a method for controlling the same, and a recording medium for performing the same. If a mobile terminal for opening the digital door lock is regarded as a pre-registered mobile terminal, information of offset and interval length regarding a password column is transmitted to the mobile terminal. If a mobile terminal is regarded as a non-registered mobile terminal, the information of offset and interval length regarding a password column is transmitted to an external control server through the non-registered mobile terminal. In response to the same, a variable value and a hash value created inside the mobile terminal or control server are received. By comparing the received variable value and hash value with a hash value calculated inside the door lock, the door lock can be opened when the two values are identical. |
