A dynamic password generation and verification method

Abstract

The invention provides a dynamic password generation verification method, which involves the following parts: original prime number library, dynamic password group generation, dynamic password traversal sequence generation, dynamic password verification and redundancy processing. The dynamic password group is generated by the original prime number library through a randomization algorithm, including n 128-bit dynamic passwords; the dynamic password traversal sequence is a pseudo-random sequence generated by UID (Unique User ID); the dynamic password is triggered by the system clock according to a certain clock frequency The pointer is dynamically generated by traversing the dynamic cipher group according to the dynamic traversal sequence; the dynamic password verification is verified by matching the decrypted result of the encrypted dynamic cipher at the current moment with the redundant password in the dynamic cipher group, and at the same time adjusting the traversal pointer to avoid system errors. After the dynamic password group is generated, it is stored locally in encrypted mode. Two mechanisms are used for dynamic password group generation and dynamic password traversal sequence generation to minimize the possibility of password cracking.
