[0013] The present invention will be further described in conjunction with accompanying drawings.
[0014] Such as Figure 1-3 As shown, the code hopping generation method of the access control system includes a code hopping terminal and an access controller. The code hopping terminal is an ordinary PC, a tablet computer or a smart phone. A number of access control terminals; among them, the code-hopping terminal is installed with a code-hopping generation program. In the program, there is a set of non-linear algorithms for generating code-hopping and an encryption algorithm calling rule table corresponding to the access control controller. Each time period corresponds to each access control controller. The algorithms are different; the decryption program of the access controller has a decryption algorithm call rule table corresponding to the code-hopping terminal and a set of non-linear algorithms for password decryption, and the algorithm for each period is consistent with t...
