CCL (Chaotic Cipher Lock) is produced by chaotic system with an enormous key space (1045) and an unpredictable chaos code to prevent a burglar from unlocking and stealing. CCL is the integration of PSoC (Programmable System-on-Chip), LCD (Liquid Crystal Display), USB (Universal Serial Bus), Keyboard, Driver and Unlock/Alarm devices that the establishment of chaotic system, CCL basic code, operation code, and Key's identity code can be implemented. Two ciphers (identity code and operation code) in between the user and CCL are required for passing the identification and unlock. When it is unlocked, the key has to be inserted to the CCL slot for identification. After being identified and correctly inputting the operation code, the driver circuit would unlock the electric lock. Various statistical methods, such as the distribution characteristics of chaos code, FIPS PUB 140-1, correlation coefficient, and key space, are adopted for testing the security. Furthermore, there have not been any scholars or engineering designers applying PSoC and chaotic system to the production of secure electronic lock. This CCL, therefore, is a theoretical and practical invention.
