Abstract

The invention relates to a method for generating a currently valid one-time release code (1) for an electronic lock (9), which can be transitioned from the locked state thereof to the released state thereof by entering the currently valid one-time release code (1). In order to provide an electronic lock (9) having very high security against unauthorized actuation, according to the invention the currently valid one-time release code (1) is generated by encrypting the immediately previously valid one-time release code (5) by means of an encrypting algorithm (6), wherein the encryption takes place in consideration of an encrypting code (4) generated from an individual master code (2) that is entered and a key code (3) that is stored in the electronics of the lock (9).

Claims

1. Method for generating a currently valid one-time release code (1) for an electronic lock (9), which can be transitioned from its locked state to its released state by means of entering this currently valid one-time release code (1),

wherein

the currently valid one-time release code (1) is generated by means of encryption of the immediately previously valid one-time release code (5), by means of an encryption algorithm (6), wherein the encryption takes place taking an encryption code (4) into consideration.

2. Method according to claim 1, wherein the encryption code (4) is generated from an individual master code (2) that is entered and a key code (3) that is stored in the electronics of the lock (9).

3. Method according to claim 1 wherein the first currently valid one-time release code (1) after startup of the electronic lock (9) is determined taking an entered individual start code into consideration as an immediately previously valid one-time release code (5).

4. Method according to claim 1, wherein AES, DES, Triple DES, Blowfish, RC4, RC5 or RC6 is used as an encryption algorithm (6).

5. Electronic lock (9) that can be transitioned from its locked state to its released state by means of entering a currently valid one-time release code (1),

wherein

it is set up for implementing the method according to claim 1.

6. System (7) having an electronic lock (9) and an electronic device (10) disposed separate from the lock (9),

wherein

the electronic lock (9) and the electronic device (10) are set up for implementing the method according to claim 1.

7. System (7) according to claim 6, wherein the currently valid one-time release code (1) is generated not only by the electronics of the lock (9) but also by a program that runs on the electronic device (10), and is displayed by this electronic device (10), wherein the same encryption of the immediately previously valid one-time release code (5) takes place, by means of the program, as in the electronics of the lock (9).
